If you' re a medium to large woodworking shop or cabinet makerr- then the AFS-1600 air filtration system is perfect for you. It features three speeds and a heavy-duty 1/2 HP motor produces a maximum 1575 cfm unrestricted airflow and provides 1370 cfm of filtered air. This will clean the air in a 45' x 45' shop every 10 minutes. This woodshop air filtration system will remove 99-percent of dust particles as small as five microns and 91-percent of particles as small as one micron in size. And the best part is that it is 110 volt and only takes 6 amps of power to run. For ease and convenience- the AFS-1600 air purifier for wood shops- like all Baileigh air filtration systems- comes standard with a radio frequency (RF) remote control allows you to operate the Air-Tech HP from anywhere in the shop- even from an adjacent room. The convenient RF remote is equipped with three speeds and a timer function that allows you to set a timer for 2- 4- 6- and 8 hour increments.
