Airstream® Duo Class II Biosafety Cabinet
The Esco Airstream Duo Class II biosafety cabinet is a double-fan/double-exhaust filter version of Esco's Airstream S-Series Class II biosafety cabinet model. Providing operator, product and environmental protection from hazardous aerosols through superior minipleat ULPA filters, the product combines the best product performance features with Esco's ergonomic design.
- Dual ULPA filters, >100,000 x better protection than single filter systems.
- Independent inflow/downflow fans, redundant system provides protection in case of fan failure.
- Auto-purge™ holes located at the front side walls eliminate eddy currents and dead air pockets in the critical area behind the sash window.
- The filter assembly is constructed in accordance with EN1822 requirements.
- Dual permanently lubricated direct-drive external rotor motor/fans assure cabinet safety in the event of a motor failure.
- Removable stainless-steel single piece work surface with large radius corners simplifies cleaning.
- Single piece formed stainless steel work surface with a curved front edge is designed for maximum operator comfort.
- Built-in warm white, electronically ballasted, 5000k lighting provides excellent illumination of the work zone and reduces operator fatigue. The reliable lighting system is zero-flicker and instant start.
- The lamp delivers uniform lighting to the work surface for greater comfort, reduced glare and improved productivity.
- Cabinets are KI-Discus tested on a sampling basis for performance integrity.
- Airstream AC2 Series cabinets are warranted for 3 years excluding consumable parts and accessories.
- Additional IQ/OQ documentation is available upon request.

- Adjustable height 395-490 mm (15.6"-19.3")
- 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 (fan plenum) at the top of the cabinet.
- Dual fans and dual exhaust filters provide an added measure of protection. If the primary fan fails, the secondary fan still pushes the air across the exhaust filters to maintain inflow and containment.
- Approximately 32% of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining 68% of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air stream bathing the work surface in clean air.
- 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 32% exhaust and 68% recirculation process is continued.
- Optimized air curtain maintains personnel and product protection even in the unlikely event of inflow and downflow imbalance that would compromise protection in a conventional cabinet.
