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 the 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.

• 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
• Two high-quality U15 ULPA filters with the typical efficiency of 99.9998% at MPPS and 99.9999% at both 0.3 and 0.12 microns provide the best product and operator protection in the world; typical filter lifespan is more than 3 years depending on ambient operating conditions and total hours in usage per day.
• ISO Class 3 air cleanliness within work zone as per ISO 14644.1 (equivalent to Class 1 as per the US Federal Standard 209E, 100 times "cleaner" than the usual Class 100 classification on cabinets offered by the competition).
• Sentinel™ Microprocessor Control system allows the user to easily access cabinet functions. Audible and visual alarms prompt the user in case of any unsafe cabinet condition, such as hardware failure or unsafe sash opening heights.
• Isocide™ antimicrobial coated cabinet structure prevents surface contamination and inhibits bacterial growth on the cabinet's external surfaces.

• 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 fi lters for supply and exhaust airflow.
• >50% less energy consumption and heat output (AC2-E and AC2-S Series) than competing products delivers lower total cost of ownership.
• Esco Sentinel™ microprocessor supervises all cabinet functions.
• Ergonomically angled front improves reach and comfort.
• Actual work opening is 25.4 mm (1") larger than tested sash opening to provide additional work space.
• Frameless, shatterproof sash is easier to clean, offers larger, unobstructed viewing area.
• Removable one-piece work surface simplifilies cleaning (applicable to AC2-S series and AC2-D series).
• E-Series cabinets include multi-piece tray components which lift and remove to provide easy access encourage surface decontamination and can be sterilized inside autoclave.
• Raised airflow grille maintains safety by preventing blockage.

• Designed for ergonomics: the generously sized 173 mm / 7 inch work access opening (203 mm / 8 inch from work surface) allows easy access to the interior; the width of the inflow air grille has been minimized in order to place the work zone closer to the operator.
• Removable, rounded front armrest extends the length of the cabinet??s front edge and eliminates pressure points on the arms while maximizing cabinet containment by increasing airflow laminarity into the plane of the work access opening.
• Work tray is aesthetically designed with upward curving back edge which facilitates ease of cleaning with no difficult to reach edges.
• Frameless glass sash for unobstructed view into the work zone and easy cleaning.

• 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.
