A2 type bio-safety cabinet is the safety equipment for research,teach and clinical examination in fields of microbiology,biomedicine,genic recombination,animal experiments and biologicals.

It adopt special design and structure to offer safe protection to environment,operators and test items.

Flow mode

1. the ULPA filtered air.

2. not filtered/might polluted air.

3. incoming air

The fan suck the coming air from surrounds into grating in the front of working table to avoid to pollute table and samples, the incoming air won’t be mixed with cleaning air in the chamber. The coming air will go through the path and flow to the pressure chamber in the top.

 30% air in the pressure chamber will be exhausted out through filter. The left 70% air will down to filter then form cleaning air to flow to working area.

The stable and uniformity air flow will protect samples, to avoid cross infection in the chamber.

When the air approach to working table, the down flow will be parted two parts, one partial will flow forwarding to grating, the other partial will flow backward.a little part of down flows after filtered will be sucked speedily to the holes of side area.

The inflow and down flow are mixed to form gas curtain to prevent the polluted gas to working area, and also avoid overfall of chamber airs.
