Biological safety cabinets
SafeFAST Elite Class III

Unlike traditional Class II safety cabinets, the Class III version is a hermetically sealed unit. Access to the work area is provided exclusively via integrated gloves at the front. All entry and exit points for materials are controlled via airlocks or transfer chambers, which also operate under negative pressure.

This makes the SafeFAST Elite Class III ideal for:

• Work involving BSL-3 or BSL-4 pathogens
• Highly pathogenic microorganisms and viruses
• Cytotoxic or genotoxic substances
• Biological agents in risk groups 3 or 4
• Use in high-security laboratories, military research or pharmaceutical development departments

• The workbench operates using a multi-stage filtration system in negative pressure mode. Both the working chamber and the airlocks (transfer flaps) are maintained at a constant negative pressure to prevent any potential leakage to the outside.
• Airflow:
  • 70 % of the air is recirculated through a main H14 HEPA filter
  • 30 % of the air is discharged in a controlled and decontaminated manner via a separate H14 HEPA exhaust filter
• Air purity class:
  • Laminar flow in the working chamber in accordance with ISO Class 3 (as per EN ISO 14644-1)
  • Prevention of cross-contamination between different samples or substances

• Energy efficiency: Power consumption <281 W
• Noise level: <53 dB(A) – quiet in operation despite powerful filter technology
• CO₂ emissions: Low thanks to optimised airflow
• Microprocessor-controlled control panel: Display of all safety-related parameters, including alarm functions
• Interior: Made from high-quality AISI 304 stainless steel; AISI 316L also available as an option for increased chemical resistance
• Segmented work surface: Easy to remove, hygienic to clean
• Safety glass side panels: Robust construction, clear view, ideal for monitoring the work area
• LED lighting outside the airflow: For optimum illumination without air turbulence

• Integrated sockets (230 V): 2 or 3 – depending on the size of the unit
• Media connections (Ø19 mm): 3 connections per side panel – e.g. for vacuum, gas or compressed air
• Motorised, hinged front panel (for maintenance by authorised personnel only) – facilitates cleaning and servicing
• Connections for DEHS filter integrity tests – GMP-compliant validation and maintenance

• Transfer chamber with internal decontamination function (e.g. using H₂O₂ or UV-C)
• Integrated pass-through windows for sterile transfers
• Interfaces (USB, RS232, RJ45) for connection to external systems or laboratory management software
• Optional extras including a touchscreen or visualisation panel
• Pressure differential monitoring with visual and audible alarms
• Special finishes or material adaptations for cleanrooms and pharmaceutical environments
• Mobile or stationary base frame: optionally with swivel castors or adjustable feet

• High-security laboratories (BSL-3 / BSL-4)
• Central diagnostic laboratories handling high-risk samples
• Research facilities handling high-risk pathogens
• Pharmaceutical development of toxic active substances
• Biotechnology production areas involving viral vectors or cell therapies
