CLASS 2 AIRFLOW
Inward airflow travels through the open front and is directed underneath the worksurface. From there, it is HEPA-filtered and delivered as clean laminar airflow to the working area.
The air is then drawn back under the worksurface, where it mixes with the incoming airflow. This mixture is channeled through the return air plenum, with approximately 70% recirculated as downflow and 30% discharged from the cabinet.
The discharged air is double HEPA-filtered and can either be released back into the room (recirculating) or through a building extract system.
Class 2 cabinets are suitable for work with all biological agents up to ACDP Hazard Group HG3 and Biosafety Level BSL-3. For level 4 (HG4/BSL-4) or applications requiring fully sealed containment, explore our Isolators or Class 3 Biological Safety Cabinets.
- Blue: Inward environment air

I do have to say that the quality of the cabinets is really good, UKHSA are very pleased.

We are very satisfied with our equipment and overall the customer service has been fantastic, we will definitely come back to CAS in future if we need anything.

I would like to express my heartfelt thanks and gratitude for the help and assistance provided to the KEMH engineering team.

I wanted to make sure it was recognised that the lads worked their behinds off to make sure I got my cabinets in place before I left for the day. Deliveries like that make my life much easier!!

I do have to say that the quality of the cabinets is really good, UKHSA are very pleased.

Our service has just concluded, please pass on our thanks to the visiting engineers – we were impressed with their efficiency and how smoothly this service round went.

The communications generally from CAS were excellent and Brian was great when on site.

The team were extremely hard working with no task being too much trouble, even offering to help other contractors that were working within the small space that we had available to us. They really couldn’t have been any more accommodating.

Just a quick email to say how grateful we are for how everything ran on Friday, we were very impressed by the speed with which everything was smoothed out and taken care of.

All good service as usual from CAS. Your engineer was very helpful, thorough and professional.
