485 CFM Electronic Air Cleaner.

The only thing small about the F57B is its size. Built to the same demanding performance specifications as the larger F57A, this smaller unit slips into any two-by-two foot space in drop ceilings with at least 13 and one half inches clearance above. That clearance can be reduced to 7 inches with the optional skirting kit. The F57B is the space-saving way to improve air quality in smaller areas like offices, break rooms, reception areas, computer rooms and copy centers, to name a few.

Contains one FC37B heavy duty commercial cell, 485 CFM, power supply assembly, prefilter, inlet-outlet grille, power and speed control switch, performance selection switch, collector test button, three-speed motor-driven fan, interlock switch for the access grille, exhaust air vent and LED indication of system operation.
