Cost Effective Solution to Operator, Product and Environmental Protection

The Esco Airstream Class II Biological Safety Cabinet is a cost effective solution to providing operator, product and environmental protection within laboratories and industrial facilities. The Airstream features the use of 2 ULPA filters to deliver ISO Class 3 air cleanliness to the work zone.

The Esco Airstream Class II Biological Safety Cabinet has been independently certified and type-tested by Health Protection Agency (HPA, formerly CAMR, the Centre for Applied Microbiological Research, Porton Down, Salisbury, UK) for compliance with the Class II requirements of the EN12469:2000 (European standard for microbiological safety cabinets). The type-testing performed included stringent evaluations of cabinet airflows, containment, and operator comfort factors.

Features:

·          Unique Esco Dynamic Chamber™ plenum design delivers quiet, uniform airflow.

·          Negative pressure plenum surrounds contaminated positive pressure plenum; no fabric bags are used.

·          Dual, long-life ULPA filters (per IEST-RP-CC001.3), for supply and exhaust airflow.

·          Sentinel™ Gold microprocessor monitors airflow in real-time via temperature compensated sensors and conserves UV lamp life with unique timer function.

·          Ergonomically angled front improves reach and comfort.

·          Frameless, shatterproof sash is easier to clean, offers larger, unobstructed viewing area.

·          Multi-piece tray components which lift and remove to provide easy access encourage surface decontamination and are autoclavable.

·          The front sash is motorized for convenient one touch operation.

·          Raised airflow grille maintains safety by preventing blockage.

·          Transparent side windows, angled front, and reduced noise levels combine to create the most comfortable, well-lit cabinet in Esco's range.

·          The Accuflow microprocessor based speed controller maintains constant, stable airflow despite building supply voltage fluctuations.

·          Esco ISOCIDE antimicrobial surface on all painted surfaces minimizes contamination.

· Ambient air is pulled through the perforations located towards the work zone front to prevent contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Inflow air travels through a return path toward the common air plenum (blower plenum) at the top of the cabinet.

· The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area.

· Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones at a higher velocity (small blue arrows).

· A combination of inflow and downflow air streams forms an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.

· Air returns to the common air plenum where the 35% exhaust and 65% recirculation process is continued.
