Bio-safety Cabinets Class II Type A2

Additional Details

“Bio-cleanair” Class II A/B3 Biohazard Safety Cabinets provide personnel, product, and environment protection. Class II Cabinets differ in the proportion as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA) filtration. Velocity of airflow to the work zone creates an ultra-clean environment for product protection, where the remaining exhaust air is discharged out. An internal blower draws sufficient room air through the front grille to maintain a minimum calculated or measured average inflow velocity of at least 75 lfpm at the face opening of the cabinet. The supply air flows through a HEPA filter and provides particulate-free air to the work surface. Laminar airflow reduces turbulence in the work zone and minimizes the potential for cross contamination. An unducted Class II type A is not to be used for work involving volatile or toxic chemicals. The buildup chemical vapors in the cabinet (by re0circulated air) and in the laboratory (from exhaust air) could create health and safety hazards. Features : Unique Bio Clean Dynamic Chamber™ plenum. Negative pressure plenum surrounds contaminated positive pressure plenum; no fabric bags are used. Dual, long-life ULPA filters for supply and exhaust (per IEST-RP-CC001.3) with 99.999% efficiency for particle size between 0.1 to 0.3 microns. Angled supply filter matches cabinet profile to achieve best downflow uniformity. Bioclean Sentinel™ microprocessor. Frameless, shatterproof sash is easier to clean. Ergonomically angled front improves reach and comfort. Actual work access height is 45 mm (1.8") higher than tested sash opening. Removable one-piece work surface simplifies cleaning. Raised airflow grille maintains safety by preventing blockage. Optional UV lamp is located behind control panel away from line of sight. (Does not apply to 1.8 m / 6' models.) Bioclean antimicrobial coating on all painted surfaces minimizes contamination. Enhanced side-capture zones optimize containment. Work area on Esco 0.9 meter (3') cabinet is equivalent to work area offered on larger 1.2 meter (4') conventional cabinet.
