LAOP, operator protection clean air enclosure
Bigneat manufactures and installs LAOP enclosures for protection of the operator from moving automated equipment and potentially hazardous fumes and particulates released from the enclosed process.
LAOP’s high performance airflow system draws air through the HEPA and/or Chemcap carbon filtration system mounted in the roof of the enclosure. The enclosure is maintained at a slightly negative pressure with air entering the enclosure through slots at low level (>0.4m/s) and this protects the operators from aerosols and/or vapours such as solvents and DMSO released from the process. Used air is exhausted via outlet/exhaust filters back to the laboratory.
Access to the enclosure interior during operation can be gained through full height sliding or hinged doors allowing for access to the robotics system inside the enclosure during use, loading and maintenance.
A control panel provides audible and visual alarm indication of low airflow.
Interlocking upper and lower main access doors are locked down with ‘T’ handles during operation.
This enclosure’s air flow is 100% pass through system, air in and air out.
