Workshop air filters.

Do you have a dust collector? The money play is to get the bulk of the sanding dust under control as close to the source as possible. The unit you are looking at will do a great job at filtering the air and dust that gets to it, but why wait, when you can jump in early.

The standard 4" hose with a galvanized forced air heating fixture on the end, which can be held to the ways by magnets will get virtually everything if you are sanding under power, because the dust will have direction based on gravity and centrifugal forces. I use mine, with hearing protection, and I can barely soil a handkerchief after a sanding session.

If you are trying to keep the harmful dust out of your lungs it is a waste of money. No repeat no DC will get the sub 5 micron stuff out of the air, The ones that say they will remove down to 3 microns will do so after the dust has caked on the filter so almost NO air can get through. That is the reason that commercial shops have the DC venting outside. If you can see it it, is not dangerous but under 5 microns the lungs can't expel it.

Uh, mine has 0.5 micron filters that move plenty of air.

Be careful with your sweeping generalizations.

In any case, the device he is looking at is not a dust collector, it is an air filter with two stage filtration to 1 micron and is intended to be used as an adjunct to a dust collector. Its primary purpose is to clear the fines that remain suspended after the dust collector has done its thing.

I may build one of those myself one of these days--if I just leave the cyclone going for a while it accomplishes the same thing but the filter draws a lot less power.

Hi J,

What make and model do you have that handles the .5 micron particulates?

Did you research any others before you selected the one you have?

thanks George

It's a Bill Pentz cyclone with Torit filters.

Yes. None of the other cyclones available at the time with adequate power would fit under my ceiling.
