This special unit is designed for applications where the integrity of solutions/specimens is maintained by HEPA filtered air and yet any harmful, toxic or unpleasant fumes & particles are extracted thus offering total protection to users.

This unit takes room air, passes it through a pre-filter, then a HEPA filter (for Class100/ISO 5 [or ULPA if required for Class10/ISO 4]) filter and then sends the filtered air down onto the working area. Contaminated air is drawn from the room, down through the front edge of the work surface and out of the building by an external fan. Likewise, air from the working area is drawn to the rear of the unit and into the same extract stream.

Created by welding virgin medical grade Polypropylene* they are not only proof against corrosion (which blights steel types) – very useful as aggressive detergents are often used when handling specimens – but resistant against UV degradation (which affects PVC/GRP), very easy to clean – and they look great!

*We can manufacture these units from PPS (which has a V0 flame retardant properties) if required.
