The Esco Airstream Type B2 Biosafety Cabinet is a high-performance Class II biosafety cabinet designed to ensure user, product, and environmental protection. Engineered for reliability and efficiency, it features an energy-saving ECM motor that maintains consistent airflow despite voltage fluctuations or filter loading.
Class II Type B2 biological safety cabinets provide product, operator and environmental protection and are suitable for work with trace amounts of toxic chemicals and agents assigned to biological safety levels I, II or III. In a Class II Type B2 cabinet, all inflow and downflow air is exhausted after HEPA/ULPA filtration to the external environment without recirculation across the work surface. They require being connected to HVAC ducting to expel the exhaust on the outside of the building.

Esco’s Airstream line ensures user safety with a fail-safe system that activates during exhaust failure or blockage. When such issues occur, the cabinet’s main fan automatically shuts down, preventing any risk to the operator. The large display provides real-time monitoring of operation parameters and offers easy access to functions through intuitive soft keys for the blower, light, UV, and electrical outlets.
The energy-efficient ECM motor maintains stable airflow despite fluctuations in building voltage or filter loading, ensuring consistent performance. Additional features, such as the angled front, narrow profile grille, raised armrest, and frameless sash, create a highly ergonomic work environment.
The internal work zone, crafted from a single piece of stainless steel, eliminates welded joints where contaminants might accumulate. Meanwhile, the dual-wall construction surrounds the work zone with negative pressure plenums, maximizing safety and containment.
This Esco Airstream AB2-4S2 is used and reconditioned. Unless otherwise specified all biosafety cabinets come with new HEPA filters installed by our technicians at our facility prior to shipment. Our testing procedures for B2 biosafety cabinets are limited, as we cannot replicate the same conditions as being hard ducted to the outside.
We recommend that you contact the manufacturer and certifier (or whoever will be overseeing the installation) to ensure that this B2 total exhaust biosafety cabinet is right for your application, and compatible with your facility.

Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly. While we may not be able to test for specific analytical applications we do our best to simulate the conditions under which the equipment will be used in your lab. If you have particular testing requirements please let us know and we’ll work with you to make sure these are addressed during testing.
We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS.
