Where critical conditions are important.
When clean room operations demand an extremely low level of particulates, the BioFit Class 10 chair can make the grade. The Class 10 is built with the sace rigid BioFit specifications, has the same comfort and ease of use, and offers the same benefits as the Class 100. But it goes one step further. The unique design of this seating does not use filtering as on Class 100 models, but rather a breather lung. The breather lung forms a flexible, expandable, and collapsible vessel sealed from the room air and open to the air inside the air-impermeable upholstered seat. so, when the seat is compressed by the user, its air moves into the lung. When the load is removed from the seat, the air in the lung returns to the seat. The seat air movement
action is independent of the surrounding clean room environment.
