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.
