Biological Safety Cabinet Class-II Type-A2 designed to protect the Laboratory staff, environment and sensitive work processes in which biological agents are used. The safety cabinet offers a superior level of contamination protection based on two advanced HEPA filters. The Biosafety cabinet configuration is freestanding. The Working area is made of stainless steel 304 grade material. The Cabinet body is made of Galvanized steel with powder coated material. Spillage tray below working surface, stopcock for draining the tray. In order to ensure consistent and reliable down flow velocity across the supply HEPA filter over the life of the cabinet, the cabinet use a pressure sensor (rather than anemometer) to detect pressure drop across the supply filter, rather than in just one point across the down flow.In order to preserve safety to the user and the environment, exhaust blowers automate balancing of downflow and inflow/exhaust velocities.The Cabinet automatically reduce fan/blower motor speed to 30% when the front window sash is in closed position to ensure reduced energy consumption when the cabinet is not is use.
