SafeFAST Classic Class II B2
SafeFAST Classic Class II B2 - safety cabinet with 100 % exhaust air for maximum freedom from contamination
For highly sensitive applications without air recirculation - certified according to NSF/ANSI 49
The SafeFAST Classic Class II B2 is a biological safety cabinet of the latest generation, developed for applications with the highest safety and cleanliness requirements, where 100 % exhaust air flow without any air recirculation is required.
This safety cabinet fulfils the requirements of NSF/ANSI 49 and offers comprehensive personal, product and environmental protection - especially when handling toxic, volatile or highly contaminating substances.
Your product benefits at a glance
- 100 % exhaust air operation - no air recirculation
- Certified according to NSF/ANSI 49 and EN 12469:2000
- Maximum safety for toxic or volatile substances
- Robust stainless steel construction for a long service life
- Quiet, energy-efficient and easy to maintain
- Extensive equipment options for individual requirements
100 % exhaust air - uncompromisingly safe
The safety cabinet must be connected to an exhaust air system. It does not have an exhaust air motor.
In contrast to standard Class II cabinets, where part of the air is recirculated, the SafeFAST Classic B2 discharges all contaminated air from the work area directly to the outside via an external exhaust air system. This effectively protects both personnel and the laboratory environment from vapours and aerosols from chemicals:- Vapours and aerosols from chemicals
- Cytostatics and toxic substances
- Volatile organic compounds (VOCs)
- High-risk biological agents
The SafeFAST Classic B2 is therefore particularly suitable for applications with increased risk or strict GMP requirements.
Functionality - Class II B2 safety principles
- 100 % exhaust air operation: no air recirculation in the work area
- Vertical laminar flow in the work area ensures controlled, low-turbulence unidirectional displacement flow
- HEPA filtration (H14) in accordance with EN 1822: Retention of 99.995 % of all particles ≥ 0.3 µm
- Connection to on-site centralised exhaust air system required - for safe disposal of process air
