The F57A,B Flush-Mount Commercial Electronic Air Cleaners are ceiling-mounted. The F57 removes airborne contaminants such as tobacco smoke and dust from the air circulated through the F57. The only thing small about the F57B is its size. Built to the same demanding performance specifications as the larger F57A, this smaller unit slops into any two-by-two foot space in drop ceilings. It requires only 13 + inches of ceiling clearance above.

The F57B is the space-saving way to improve air quality in smaller commercial areas like offices, break rooms, reception areas, computer rooms and copy centers to name a few. Highly efficient, the F57B captures over 94% of particles (0.5 microns or larger) from the air passing through the filter. Then it re-circulates cleaner air throughout the room using Coanda air flow pattern.

Like its larger sibling, youÆll hardly know itÆs there. The off-white grille matches commercial fixtures and a hinged door swings down for easy access to both pre-filter and electronic cells. Optional carbon filter are available to help control odors. You can operate the F57B at any of the three speeds using push buttons on the unit. Other control options include a four-position wall switch, and a wireless remote control.
