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/ULPA 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 just one point across the down flow. The pressure sensor encased in order to protect the sensor from temperature, humidity, and other environmental phenomena that can impact the sensor’s performance. In order to preserve the safety of the user and the environment, the exhaust blower on the cabinet must continue operating when the supply blower stops working. If the exhaust blower  fail, the supply filter will also be turned off. The Cabinet motors automatically adjust the airflow speed without the use of a damper to ensure continuous safe working conditions, even without maintenance adjustments.
