Bio Safety Cabinet Class II, Type A2 provides product, personnel and environmental protection. Designed and manufactured as per NSF 49 of US standards. Suitable for general microbiological work with agents assigned to Bio Safety levels 1, 2 or 3. Incorporates HEPA filters of minimum collection efficiency 99.997% for particles of size down to 0.3µ and EU 2 Panel filters having average arrestance of 65% - 80% of atmospheric dust. The front panel slope allows for maximum visibility into the work zone.Cabinet’s armrest is raised above the work zone to ensure that the operator’s arms do not block the front inflow perforation.Easy to clean SS 304 grade worktop will never rust, chip or generate particles.The Clear Polycarbonate front sash provides greater Operator protection from harmful U V rays. The front sash is counter balanced for up and down movements. 30% HEPA filtered exhaust air leaks into the Laboratory & 70% HEPA filtered air comes down after filtration into the work zone.White light and UV lights are located outside of the down flow air stream to ensure optimum airflow uniformity. Superior electrical safety for the operator since all cabinets are factory tested after production at manufacturing site. Laboratory air is drawn through the front perforations (inflow) to compensate the exhaust air for providing -ve pressure inside the Cabinet work zone. The contaminated air is initially Pre filtered before recirculation and the contaminated air inside the work zone from the common plenum is connected to the blower chamber for exhausting through exhaust HEPA Filter.   All components are designed for maximum chemical resistance for longer service life and durability. All cabinet components area clean room compatible.The main body constructed of galvanized steel with an abrasive resistant white powder coated finish.

When the raw material needs to be sampled/dispensed within a clean environment, the Sampling/Dispensing booths will provide both operator as well as product protections from external contamination.Designed and manufactured to meet the cleanliness level, as per US Federal Standards 209 E. The main body constructed out of SS 304.White lights situated in the side panels offers excellent illumination throughout the work zone through translucent sheet and is outside operators line of sight. Separate switches have been provided for the blower and white lights.In addition 5/15 amps socket/s provided inside the work zone for connecting the balance. Superior electrical safety for the operator since all cabinets are factory tested after production at manufacturing site.Permanently lubricated direct driven centrifugal blower[s] having extremely low noises and vibration due to propriety construction and are suspended on springs.All components are designed for maximum chemical resistance for longer service life, durability and are clean room compatible.Two pressure gauges are mounted on top plenum to indicate the pressure of HEPA [supply] and return air plenum respectively. Room air is taken in from the bottom of the cabinet through a pre filter this serves to trap larger particles and increase the life of the main filter.Air is forced evenly across the HEPA filter, the result is a stream of unidirectional air within the safe work zone of the cabinet.A nominal filter face velocity of 0.45 m/s or 90 rpm ensures that there is a sufficient member of air changes within the enclosed safe area of the cabinet in order to maintain cleanliness.The purified air (80%) travels in a vertical unidirectional stream and remaining air is exhausted through the exhaust HEPA in the top plenum.
