Hang an AT750 at one side of the shop, oriented to create circular airflow around the room, and you'll quickly finish the job begun by your dust collector of making your shop a cleaner, safer and more pleasant place to be. It moves up to 750 CFM through its ultra-fine filters, enough to filter all the air in a 20' x 30' x 8' shop roughly ten times every hour. That's 750 CFM of filtered air--real world output, not an unfiltered fantasy figure. Variable speed lets you choose the amount of cleaning power you need. A pleated pre-filter removes coarse dust at the intake, and the machine's second stage industrial bag filter then captures 99% of 5 micron particles (91% at 1 micron), removing dust, pollen and fungi.
Model 750 has a 1/4HP, 3 amp motor. Housing is 12" x 24" x 34". Weighs 72 lbs.

For larger shops, Model 8-12 moves up to 1250 CFM, more than enough for shops up to 11,000 cubic feet.

Model 10-16 cleans up to 1600 CFM, overkill for shops up to 16,000 cubic feet. Both units are 24" x 44" x 20" and weigh 86 lbs.

Commercial-duty Model 2400 is for large shops, exchanging the air in a 50' x 50' x 10' area every ten minutes. It measures 24" x 25" x 55" and weighs 203 lbs.
