     Hi Tink ,

                     I use  an air handler with the electric heat strips strictly as a furnace in my shop .

              I built a plenum underneath out of plywood and made a second slot or pocket for a double filter system . It seemed as though it was restricting the air too much and starving the unit for my heating requirement so I only use the one filter now .

    To use it as a dust filter in the shop , will you orient the blower to exit the shop ?  If not imo it will only blow dust around your shop if it does not exit the building if I understand you correctly .

            good   luck          dusty

   It would be similar to the air filters sold by Lee Valley, Sears, or others but probably somewhat more potential for volume as it has three speeds (must be hardwired to change speed).  I wasn't intending to exhaust it outside.  Outwardly, it doesn't seem as it would be any different if the clean air was coming in from an open window, or cracks in the wall or from the exhaust of the air cleaner.  I have heard disparing remarks from others saying the air cleaners aren't all that good.  May not be worth the effort.  I have hot water heat in the floor for heat so don't need it for that.

     tink ,

               I think the air cleaners actually create a circulation of the air and then zap the dust particles , and to my knowledge they do not exit or exhaust from the unit . An air handler does not have the ability to zap or rid the air of particulate matter that I know of , with the exception of what the filters trap which is only a portion of the total . When I create a dust cloud near the intake even after the filter the dusty air is blown into the shop .

   When you mention zapping the dust particles out of the air, does this mean the air handlers use the electronic air cleaning.  I am pretty much unknowledgeable about them.  I suppose a person could install electronic cleaning in the system but it probably would be price inhibiting.  As just filters go, I would attempt to put in the same filters as the commercial units use.

   I too am at the same stage you are at with an air cleaner.  I have an old electric furnace which I will gut,  and plan on installing two pleated bag filters and two pre filters.  The Jet AFS-2000 air cleaner has a 1/3HP motor and will do 24 air changes/hour in a 20 X20 X8 area(6-8 changes being considered OK) And not to restrict the air flow or tax the motor I plan on using 2 pre and 2 inner filters.  Jet outer filter is 5 micron and the inner filter is 1 micron(8 pocket)JET Part numbers are,

   washable outer  708724, outer electrostatic 708722, charcoal filter 708721, inner filter 708723.

   I know this set up is way over kill.  But can we really overkill as far as dust is concerned?

   When you mention 24 air changes per hour, you may be getting a lot of noise.  I don't know how many air changes I got with the air handler but the noise level was irritating.  Of course this was in the house and it probably wouldn't be so irritating in the shop.  I do think that with that many filters, it will slow down the volume of air though.  Will you be installing those filters in series or some in parallel?  I have 3-speeds so I can jack up the speed if I need to.  Are you familiar enough with the air cleaner that you know whether they are worth while?  By the way, where can I get those filters that you mention?  I looked in the Lee Valley catalogue and theirs was quite a bit smaller than what I would need.

   The Filters I mentioned are approximately 22" X 26".  I will be running them parallel which will give me maximum surface area and minimal air flow restriction.

   Air cleaners are definitely worth the effort. Especially when it comes down to preserving your health and lungs plus the added benefit of clean air when you get down to applying a finish.   These filters also  available in a charcoal version that absorb solvent vapors and odors, A good thing.

   You should be able to special order the filters from your local Jet distributor or give Jets parts/service number a call 1-800-274-6848Work Safe,  Count to 10 when your done for the day !!
