Microclene MC1000

Introduction.
I figured it was about time to get serious about dust collection and filtration. I looked out the door into the sunlight the a while ago and the amount of suspended dust I could see gave me cause to think.

The dust sizes that woodworkers typically have to worry about are from 0.4 microns to about 8 to 10 microns. There are a number of sites that give some excellent information on dust collection, perhaps the best is run by Bill Pentz. If you have only a little time to read today, I suggest you leave this review now and read Bill Pentz's introduction instead - it may lengthen your life.

Generally, hand tool users have little risk to dust in the workshop. It mostly comes from machines. Blunt blades will create more dust than sharp ones. Table saws, routers, jig saws, drills, morticers, jointers, thicknessers etc all eject massive amounts of fine dust - Bill Pentz says nearly 5% of dust created is the fine invisible dust (the 'bad' dust). A note for hand tool users though, shavings and other timber pieces laying on the floor are slowly ground to dust and kicked into the air as you walk on them. If you like a workshop with 'atmosphere' you may want to consider the ramifications for your health.

There is no single solution to the dust problem, it needs a staged approach to minimise the risks to the woodworker. First you have dust extractors, then air filters and finally dust masks. Note that the single best way to avoid dust is to get it at the source, use a good extractor and eject the air outside the workshop (but away from neighbors please) and to also wear a suitable dust mask capable of capturing down to 0.4 micron particles. Unfortunately, once you take off your dust mask you immediately begin to inhale the fine dust you have tried so hard to avoid; this is where the air filters come in.

Despite your best efforts, fine dust will escape the dust collector and become airborne in the workshop. You cannot see this dust and it floats on the air currents. When you inhale it goes into your lungs. If it is larger than 0.4 microns it cannot pass through the lung wall and be ejected by normal bodily functions, therefor it sits in your lung.

A good air filter will rapidly process large volumes of air, removing particulates down to 0.4 micron. The key is to get a filter that will remove the smaller particles and that can also process the air in your shop quickly enough to minimise the exposure you have to the fine dust.

Selection.
I only looked at two styles in detail, these were the large rectangular roof mounted units from Jet and Carba-Tec and the Microclene MC1000 (click on the pictures to go to the websites).

http://www.carbatec.com.au/images/th...s/CTF-1000.jpg http://www.microclene.com.au/assets/...1000_small.jpg

My workshop is 5.6 x 6.0 x 2.7m. The primary requirement was to filter the 90 cubic metres of air about 10 times per hour. Secondary needs were for it to be small (2.7m ceiling and I am 188cm), mobile and relatively cheap to run. The reasons I chose the Microclene MC1000 were:

• It removes 65% of particles down to 0.5 microns and 95% of 1 micron particles.
• It can filter the air in the workshop over 10 times per hour,
• It is small and easily moved,
• It is a 100W motor so is efficient to run.

Even though the Jet and Carba-Tec units had better flow rates their filtration is not as good. The Jet and CT units each claimed 98% of 5.0 micron particles and 85% of 1.0 micron particles. The Microclene started at 95% of 1.0 micron particles and went down to 65% of 0.5 micron particles, the only one to concentrate on the really fine particles.

Flow rates
Microclene MC1000 = 1000 cubic meters per hour
Carba-Tec 650cfm = 1104 cubic meters per hour
Carba-Tec 1700cfm = 2888 cubic meters per hour

Price.
The Microclene was not cheap at $765 (it shipped with a complimentary $27 spare filter), but since the other units did not remove the damaging dust below 1 micron they did not meet the required specification and were (arguably) more expensive in the long term health-wise. The smaller CT unit was $459, the larger was $899.

MC1000 Review
Finally, on to the review. The unit was ordered as a Christmas present and shipped on time. Dealing with the company was easy and very helpful indeed (according to my son).

Shipping. The parcel was shipped in a well protected and very clearly labelled box and arrived in plenty of time for Santa to wrap.

Instructions. These were clear and concise, they are also downloadable from the web in PDF format. There are some very minor issues with the manual: it uses the term "mcfb" repeatedly without explaining what it is. I assume it is micro-clene filter box or similar. There are typos e.g. "sgrew" (screw) and they do not explain the filter cleaning at all. Is it possible to wash or clean the filters, or should they be replaced? I have read elsewhere there are people who are vacuuming the filter and continuing to use it. It would be nice to know whether this is a safe practice or not. I suspect it isn't, as the filters will load up with small particles and become less efficient. In addition, the vacuum used to clean the filter is unlikely to have a filter as good as the Microclene, therefore it will simply pump it all back into the air for you to breathe, which obviates the reason you bought the unit for in the first place. EDIT: Regarding the cleaning of filters; the distributer advises that used filters should be replaced (for the reasons mentioned) rather than cleaned. Vacuuming or blowing with compressed airis not endorsed. Filters should not be washed. Replacement of filter is easy to do and is much safer to simply discard used filter in sealed plastic bag.

Installation. Setup was very simple, initially I hooked the unit onto an existing ceiling hook, plugged it in then turned it on. Later I welded up a few overhead bars near the lathe and tablesaw for it to hang from. EDIT: The correct way to install is via TWO suspension points or using the mcfb bracket available from the supplier. I have included a photo of my installation below.

Attachment 100030

Functional test. On startup you can see the torque twist the unit to the left as the motor spins up to operating RPM. There is a warning in the manual that the unit can unscrew a twist-style hook after multiple starts due to this torque effect.

It appears to work just as advertised. At the tablesaw I can feel the air being drawn from behind me, picking up the dust and then cleaner air blowing across the roof over my head. Unfortunately I cannot measure the size of particulates are being sucked up and will have to accept their claims to meeting the standards in that regard. The unit is a little noisy but it is air noise, not mechanical noise, and to be expected.

The unit hangs from my low ceiling and doesn't hit my head, so that is a plus :2tsup:. It is only 22.5 cm high and 30 cm in diameter so it takes very little room. I noticed the cable is the same as a computer monitor cable so loss or damage will be easily and cheaply replaceable.

At the end of a day of using the tablesaw, thicknesser, sander, jointer and dust collector the air felt clean. For once I was not blowing home made dowels into my hanky and that indicated my lungs were also clean (er). :2tsup:

Hidden benefit. :)
I have found that in use the unit doesn't just filter the air, it also cools my workshop. Most other units suck in air at one end of a box and pump it out the other so the air remains in the same plane. The MC1000 sucks air in the bottom then blows it out the sides near the top of the unit, creating a rising column of air. This sucks cool air from the floor and blows it across the roof, forcing the hot air out of the shed. It is so comfortable that I find I turn the unit on just for its cooling effect and no longer use my other fan; therefore offsetting the air filter operating cost with fan running costs.

Likes:

• Filters down to 0.4 micron.
• Cools the workshop
• Small size
• Cheap to run
• Simple, no fuss unit.

Dislikes:

• Cost, this unit is expensive at $765. To be fair though, the other units I looked at did not filter to the same degree so a direct comparison on cost is unfair to the Microclene.
• Minor omission from the manual about cleaning the filters.

Summary.
Once I get over the cost (ouch) it does everything I wanted it to do and more. The cooling of the workshop is a big plus for me, I have a low metal roof and I get a large amount of heated air from the shoulders up. This unit solves that problem and also means I do not have to run the other cooling fan that I normally run, so there are cost savings too. Its portability means I can easily move it to be overhead my lathe, workbench or tablesaw with very little fuss.

Bottom line - a well designed machine that will get a lot of use in my workshop.

Thanks Groggy, a timely post, I am in the process of setting up a new workshop and had thought of installing a filter system.

Do you really have to relocate the unit when you change machines?

Sorry Goggy this situation doesn't stack up physically. If the microclene sucks cool (dirty) air up from the floor and blows warm (clean) across the roof and out of the shed you are losing all your newly cleaned air out of the shed. If this warm clean air goes out of the shed new air has to come into the shed from somewhere and that is of course outside. All the Microclene seems to be doing is getting rid of warm clean air from your shed and bringing fresh (cooler) air from the outside. If this really is the case you could have saved yourself a lot of money by simply installing an exhaust fan.

Fans alone cannot cool air anyway, what you might be feeling is just evaporative cooling because of the moving air. If all the (warmed clean) air stays inside the shed any initially cool air at floor level will soon be mixed in with the rest of the air in the shed anyway.

Fresh air from outside will still have a bazillion particles of all sizes but there will be far fewer of the potentially nastier wood fibres. If you need a low particle count for say glossy finishing surfaces then your shed will need to be airtight to retain the cleaned air inside the shed, but then the 100W has used has to go somewhere and it will then eventually heat up a shed. I have worked in a shop where several microclene type units were in used. The shop was relatively airtight, so relatively clean air but the overall effect was to heat up the shop - good in winter, not so good in summer.

No, but it is better to capture the dust at its source before it spreads itself around. It also sets the airflow away from your face if you position it correctly.

Not all, less than 25%, mostly displaced hot air through the garage door, the walls of the shed retain most of the rest of the clean air.

All the Microclene seems to be doing is getting rid of warm clean air from your shed and bringing fresh (cooler) air from the outside.

...and blowing unfiltered air and dust all over the neighbors and the wife's washing while still breathing airborne dust in the workshop after removing my dust mask? I like my life, such as it is, so I will pass on that idea thank you :wink:.

I cannot work in my shop with the doors closed, it is simply too hot and dusty. Bringing in some fresh air to exchange with the hot air in the shop is not something I want to stop, I like it :) . I have had another forumite here and he also agreed the unit helped to keep the workshop cooler. It is more easily accepted when demonstrated than explained.

Fans alone cannot cool air anyway, what you might be feeling is just evaporative cooling because of the moving air. If all the (warmed clean) air stays inside the shed any initially cool air at floor level will soon be mixed in with the rest of the air in the shed anyway.

This would raise the average air temp in the workshop significantly. By expelling the high layer of hot air near the metal roof and drawing in cooler air it reduces the average temperature.

The low particle count is something I want for my health rather than for finishing, however it certainly removes the fine dust that usually floats around, so finishing should benefit too. Mind you, I would not be running the unit when spraying or using thinners as the electric motor sucking all the fumes up in an enclosed area is not the best idea.

The bottom line with this discussion is that it does not relate to the MC1000 specifically but is rather a side topic related to selection, positioning and use of filters in general.

Hi all

I'm a bit new to this woodworking game, and a little disturbed to find that almost all wood dust is carcinogenic. However, I have recently had a moment with my (cheap-???? Kmart/BigW/Target) vacuum cleaner where I went into the vacuum cleaner store and asked for a replecment filter, only to be told

"Well the model you have no longer has filters produced for it"
" but I only bought it 5 months ago"
"well they no longer make the filters for it"

After 3 Vacuum cleaners u think I wooda lerned...

So I cracked it and bought an expensive vacuum cleaner with washable HEPA filters, and cyclonic action etc.

So... How do I buy a shop Vac where I either have washable/cleanable filters, or get a reputable brand where they produce consumables for it over the expected life of the unit ie 5-7 years.

You get that too? :D

A very good review, this sort of comparison is something I needed back when I was looking at the usual suspects air filtration units. However it's been done and I have the larger H&F unit.

Just about to pull the pin and purchase one, just had a look on Microclenes website, the units now worth $866!

Jeeze are they twice as good as the carbatec/jet units? Its was hard enough getting the ok from the minister of finance at the old price!

Thankfully I got mine before any price rise (for once yay!). These are not 'twice as good' however they do remove the smaller particles. Have a read of BobL's comments and my responses to him. You should find a bit of both worlds there. My *opinion* is that this is one of the better air filters around because it removes the finer particles that can harm you. A filter that only captures 'most' of the dangerous stuff is like a boat that doesn't leak - much. Either it works or it doesn't. However, there are other ways to manage dust and BobL and others have found ways to do this using airflow, fans, venting outside etc. I suggest you look at all opportunities available to your situation and go from there.

I don't regret getting the microclene for a second. Now the initial outlay is a fading scar I enjoy having it running. It IS a bit noisy, but not in a bad way. As I said earlier, it is wind noise, not mechanical noise. It works very well in my workshop with a low roof and blows the filtered air to all corners of the shop.

I have not yet had to replace the air filter and it would have at least 50-60 hours of use on it, it doesn't even seem close to getting full. Because it sits over the tablesaw I do want to move it to sit over the lathe on occasion. This is because the lathe is currently in the 'dead air' corner of the workshop and although the filtered air gets in that corner my body blocks the airflow. I will be moving the lathe sometime this year and working on the dust extraction and filtering for it.

Overall, have a look at all the options including exhausting air away from the workspace. Each works and suits a different situation. I like the Microclene because exhausting dusty air outside is not an option. It lets me work in a mostly enclosed space with much cleaner air. I still use an air hood with the lathe, a dust mask with sanders etc but when I remove the mask I know the rest of the bad stuff is being quickly removed from the air. Otherwise I'd have to leave the mask or hood on for a lot longer.

Thanks for the feedback Groggy. I gave them a call yesterday and boy did the guy on the phone know his stuff.:2tsup:

Also noticed the mc1200 is only about $60 more than the mc1000 now.

Hi Joez,

I wonder if they will at the Working with Wood Show, if so, there could be some discounting. Do you have a preference for the mc1000 or the mc1200?

Just called them again, yes they are going to be at the wood shows, no discounting or stock available just demoing the units and taking orders.

You can get a demo unit for 2 weeks (just leave your credit card details) if your serious about getting a unit.

My workshop is about 105m3 so either unit will work, for the $60 i'd be inclined to go for the mc1200 as the extra height isnt an issue for me.

The Microclene claims to filter smaller particles more effectively than the competition. I wonder if this is the result of using more efficient filters or how the return air is dispersed within the room. If it is due to the filter type, why can't the opposition use such filters?

Not sure Zelk, but its probably a bit of both

joez

I had a Microclean 1200 (I think) when they first came out 10 years or more ago.

I only kept it for a few months then sold it. I didn't like the way it exhausted the filtered air in a rotary action.

It probably filtered ok but in a high dust level enviroment, like power sanding bowls, the circular action of the exhausted air blew dust all over the workshop.

So while it caught some of the dust it also sprayed plenty around the workshop.

I suspect this type of unit works best in a low level of floating dust.

I replaced it with a Carba-tec mid size unit. Now I have some control over the direction of the exhausted air flow. It helps create an airflow direction from one end of the workshop to the other end where there are 2 x 12" extractor fans in the wall.

With all this running there is a gentle breeze flowing through the workshop.

Unless the different units are all tested by the same independant authority I would take any claims about filteration figures with a grain of salt (or dust).

Then you could really compare apples with apples.

I think a good approach for the fine dust is to use a Negitive Ion Generator. I have one on all the time the power is on (dead man power switch). Again I can't make any claims about this as it would need independant testing.

My main line of attack is a power respirator and a ducted dust extractor to catch most of the dust at the source.

Finally one of the most important things, is good house keeping. No point in having all the above equipment, if your tools on your bench are covered in dust. Pick them up, or move them and you create a dust cloud just under your nose.

For what it's worth that's my experience.

Cheers

Interesting comments Tim.

While you had the Microclene 1200, was it mounted above where you were power sanding?



Zelk

I am not sure how Tim used his, but none of the filters are intended as primary dust extractors. For power sanding on a lathe or router work a dust extractor or vacuum should really be used to get the majority of the dust.

I have seen a shroud used (a big tube really) around the microclene to focus its pickup area in one spot.

I agree Groggy, I'm still wondering whether in Tim's situation, the microclene was poorly positioned. Naturally, the expelled air is going to stir some dust up, but it is a question of where the operator and machinery is in relation to the unit. I feel that the microclene and the machinery must be in the centre of the workshop for max efficiency. This is not the case with the box style air filtration unit which is mounted to the ceiling to the side of the workshop. Ideally, the residual dust from operated machinery should be collected before reaching the operator, as equipment is in various workshop positions, choosing the right style of filtration unit may be important.

Zelk

I had my Microclean mounted above head hight, just in front of the lathe.

It was used in conjunction with the other equipment mentioned in my earlier post.

For me, the hardest operation for managing the dust is power sanding large diameter (400mm plus) work on the lathe.

Power sanding the outside of a large bowl or platter is not too bad. I usually run the lathe in reverse and can direct the dust stream into the mouth of the dust extractor. This catches most of the dust being generated.

Power sanding the inside of larger pieces presents a few more problems. The centrifugal force tends to make the dust collect on the inside near the rim. Moving the sander into this area releases this dust in a large cloud, which is difficult, if not impossible, to collect with the dust extractor. The dust is sprayed in all directions in one quick burst.

On larger pieces and if the shape permits I’ll power sand with a random orbital sander hooked up to my shop vac. This is virtually dust free power sanding. A slow speed of about 50 rpm works best, much faster and the sander tends to bounce on the work.

It is not my intention to rubbish Microclean or any other air filter system. However they should not replace
1: A dust extractor to catch as much dust as possible at the source
2: Personal face protection such as a power respirator or face mask.

I find extractor fans to be a quicker method to a clean air environment than using air filters. No filters to buy and a lot more capacity for your dollar. Extractor fans also work for fume extraction when using glues and finishes.

There is no single solution to managing dust. It needs to be a coordinated approach from a number of different directions including good house keeping.

That’s been my experience for what it’s worth.

Cheers

Thanks for that Tim, so in your case the exhaust of the filtration unit is as important as the filtration itself, at the end of the day, the residual dust should either be sucked away or blown away from the operator.

Zelk

Thought it worth mentioning that the motor failed last week. I contacted Microclene and they said send it back; no questions, no fuss. Yesterday the unit was back home sitting in its proper place and I can breathe easy again.

Along with it came a few filters 'for my trouble' and a note explaining they had a batch of bothersome motors, since remedied. They also explained the new warranty provisions which very few repairers will do unless asked (12 months).

Pretty good service!

Thanks for review groggy. No good to hear the motor died, but do it got replaced.

Does the microclene unit had a timer or remote?

Thinking of getting the 1200 if the tax return is good...

No timer or remote, but being such a low wattage unit any 240v unit should be fine.

The unit went on the Monday and was back on Thursday, very quick. I reckon things will occasionally have problems, it is the nature of manufacturing. The real issue is, are things simply fixed or do you get into a shouting match and walk away feeling peeved. In this case it was very pleasant and no effort at all.

As Joez said, I use a simple remote switch and also have a timer (for when I have cut mdf). It is kept by the door and is very handy. The remote also runs a few small lights so I don't shin myself when going into the shed at night. The light switches are on a far wall.

Groggy, I just read through the review thread and one thing stuck out a little as bad practice. In the original post, there is a picture of the unit hanging from a yellow crossbeam with the power cord wrapped around the cross beam.

If the beam is conductive, it becomes a shorted secondary winding in a transformer, with the power cord wrap acting as the primary winding. This frequently consitutes a hazard and a point of excessive voltage loss/overheating of the cord.

Probably not significant for a 100W load, but definitely not regarded as good practice. I mention this as a general warning about the practice, rather than a critisism of you or your method.

Good point malb, I didn't even consider it. It is no longer like that but I'll bear that in mind for the future :2tsup:

Great review. I picked up one of the MC1000 units last year and have noticed the improvement.

One thing I would add though. If you're in Oz, an option worthwhile considering is purchasing from overseas. I ordered mine from The Toolpost in the UK. Even with the additional cost of International Expedited shipping, I saved a few hundred dollars.

If you purchase from uk just state you want the Aust power cord & should come with it the rest is identical & you save heaps.

If you read the posts, you will find that mine was returned and repaired under warranty. What would shipping to UK and back cost? Sure as eggs the local distributor would not be honouring a warranty from UK.

No argument from me thats the risk you take with bringing in anything from o/s , yes you had trouble with yours hopefully no more now its fixed,but I still like to live in the world of you pay for what you get & I reckon I am still paying enough to buy a quality product that will last me a fair while without wty issues, but hey will cross that bridge if n when it comes, but I do have the back up of rellies in the uk :)

Hi Neal,
I represent Microclene in Australia and I would like to clarify the warranty issues with Microclene units supplied to the Australian market. Groggy mentioned we had an issue (goes back a couple of years) with a couple of batches of motors from our supplier which exhibited more than acceptible levels of warranty claims. After much tooing and froing ?? (and testing) with our supplier, it was noted that our voltage in Australia is about 10% higher than that in the UK and Europe (by far the biggest market for Microclene at this stage. Our nominal 240 V (+/- 10%) compared to 220/230 V(+/- 10%) was enough to cause these intermittent failures. The motors fitted to the units now shipped to Australia are fitted with a motor with stronger windings to suit our slightly higher voltage. The equivalent units supplied in Europe and the UK may not be fitted with this stronger motor and hence any unit bought from an overseas dealer may be subject to failure in Australia. All units supplied in Australia by Microclene Australia are tested individually under Australian conditions and supplied with a serial number for any warranty issues. Failed units which do not have this Australian label will not be serviced by Microclene Australia. The dealer overseas should be contacted for any warranty concerns.
I trust this clarifies this issue- if anyone would like more specific information I can be contacted via the microclene website.
kind regards
Stephen Diver

First of all sorry this is looking like a hijack of your article Groggy it was certanly not meant to be, just mentioning a means of saving a dollar.
Thanks Stephen for clearing up the warranty facts, I have done some research & am confident of no problems from my unit (when it gets here).
Anyhow off to pull the head in now,:seald:

Neal, no worries from me. :)

The point of the review was to give readers an idea of what the unit is like. Warranty is important for an item like this so a discussion of the pros and cons should help those trying to decide.

Having Stephen Diver from Microclene drop in to clarify things certainly helps too. :2tsup: (I did not contact him in case anyone was wondering :no: )

Neal,

I assume you have received the Microclene unit from the UK by now. Is the unit working okay and did you replace the plug with an Australian plug or do you use an adaptor? I was told by Toolpost to replace the plug. Th cost saving buying the unit from the UK is quite substantial even after allowing for shipping costs.

Rob

Hi yes the unit arrived safe n sound with Australian plug supplied has not had a lot of use yet as there are Mt roads to conquor on the Trumpy more than the desire to make wood dust, but happy with service/ product so far its like said above wty versus the $ your call, I have faith in the product & with my decision.

Cheers

Microclene have given us an updated price list for 2011.

There is big reductions in the pricing of all of their units.

They have been very aware of all comments good and bad on the forum and this is reflected in the new direction they are going with these products.

They know they have some of the best and inovative room air filters on the market and want to get more woodies protected from the harmfull airborne dust.

Have a look here at the updated prices

Remember these units are covered by the full australian warranty.
Any units purchased form overseas will not be covered by the australian importers

Jim

Can I send mine back for a refund and buy a new one at these prices :D

It would be interesting to know a bit more about what the Microclene specification for filtration means.
ie "Filters particles down to a mean size of 0.4µm"

Since no filter can filter 100% at any particle size the industry standard specification for HEPA filters is expressed as "xx.xx% of particles of y microns or greater", are filtered.

A reasonable specification is x=99.97% and y = 0.3 microns

A good review on a workshop necessity, thanks.

I have been looking at dust collection and building my own for quite awhile. At the moment the need is not critical for the shed...see Turning forum for details.

I have looked at Bill Pentz's web site and have downloaded all the relevant info and intend to build a general cyclonic dust collector which will be housed out side the workshop. As I have a couple of decent dust fans that will make good units for a cyclone.

I think I will also fit ventilation fans and vents to each end of the shed as well, for a reasonable portion of the years I get a prevailing breeze blowing over the shed and will orientate my vents etc to catch this breeze as well.
