The Marvel Scientific MS24FASF (formerly the 4FAF) is a 4.5 cubic foot Flammable Material All Freezer that is appropriate for non-critical temperature storage applications. It uses a “G” shaped plate-type evaporator installed across the top of the interior. Its large surface area efficiently absorbs heat to cool the well-insulated interior which is all dedicated freezer space.

The MS24FASF features a static condenser and requires additional ventilation clearance when installed under a bench. Construction features include a specially designed compressor, overload, relay and thermostat system with all electrical components enclosed to prevent accidental ignition of flammable vapors from the freezer’s contents. It is supplied with a commercial power cord and a 3-prong NEMA 5-15P plug for connection to a standard electrical wall outlet. When installed under lab benches or within casework, it requires additional ventilation clearance of 1″ from top and sides of the cabinet and 1.5″ from the back to insure proper static condenser ventilation.

  • Listed in Underwriters Laboratories File SA7488(N)
