Thermo Scientific Forma Class II, Type B2 Biological Safety Cabinet

Maximum Protection, Customer Conveniences

· Cabinet's 12.0" (305mm) supply air intake and exhaust ducts include adjustable, zero leak damper for convenient connection to your in-house systems. · Service valves can be plumbed from the side or rear of the cabinet for convenience, and all maintenance procedures can be performed from the front of the unit. · Pressure differential switch continuously monitors the exhaust pressure for safety.

In the event of inadequate exhaust, the pressure switch interrupts power to the supply blower/motor, preventing contaminated air from blowing onto you or into the lab. · Exhaust failure alarm includes normally open, normally closed, and common remote alarm contacts to provide an output signal for remote monitoring capabilities via your in-house central alarm systems.

Specifications and Ordering Information

Total Exhaust, Total Safety Room air is pulled into the cabinet by the blower and pushed through the supply HEPA filter, providing clean unidirectional air onto the work surface. Approximately 50% of this work area air exits through the rear grille. The remaining 50% meets room air and is pulled into the front intake grille, providing a protective barrier. The divided downflow and inflow air then combines and is pulled up the rear plenum through the exhaust HEPA filter by the facility exhaust system.

Optional Adjustable Modular Stand Stand is designed in accordance with American Disabilities Act (ADA) guidelines. Work surface height is adjustable in 1.0" (25mm) increments. Stock No. 191580 191581 Description For 4 Ft. B2 Units For 6 Ft. B2 Units
