LA Range: LAC2

Performance to Class II levels of protection for operator and sample/process.

Bigneat’s LAC2 Class II type enclosure is constructed following years of experience. LAC2 provides operator and sample/process protection in closed or open conditions. The enclosure interior is accessible through sliding windows in the lower door (access 300mm high) through which high velocity inflow air enters (minimum 0.4m/s) providing operator protection and sample/process protection. This laboratory air then flows into a profiled grille extending the full width across the front of the enclosure.

Custom designs for this model of enclosure provide for front and side access, front and back access (plenums in side walls for airflow – ‘split innovation’ in the fan housing is unique to Bigneat).

The enclosure includes an epoxy-coated steel stand with self-levelling/lockable castors for full mobility.


  • Providing in-process operator and product protection (sterility) with access via 300mm high sliding windows.
  • Programmable control system – displays enclosure status and controls airflow system balance, hour counter.
  • Display show status of enclosed robotic system is mounted to enclosure exterior.
  • Audible and visual alarm indication of low airflow and door open warning.
  • Hydrogen peroxide connections, or alternative sterilisation, night doors, removed for normal operation and access.


Performance and Standards:

Meeting recognised Standards worldwide including: NSF Standard 49, Category A2 and EN 12469: 2000.

For use with Class II biohazards.

LAC2 provides for operator protection from hazardous aerosols and particles and providing product protection from contaminants entering the enclosure whilst in operation.
