It is built to the same rigid standards, offers the same comfort and ease of use, and provides the same benefits as the Class 100 chair above, but it incorporates a unique particle retention system that guarantees Class 10 compatibility. Instead of a filtering system, it features a breather lung: a flexible, expandable and collapsible vessel hermetically sealed from the cleanroom environment but open to the air trapped inside the seat. This vessel "breathes" to allow comfortable compression and expansion of the seat—while minimizing the risk of particle escape. The durable, nonshedding vinyl upholstery is completely sealed to the lung (or to the back cushion) to ensure that no particles are emitted from the edges of the chair. (See typical performance data at right).

These chairs are available in standard and static-dissipative vinyl to meet your requirements. All are noncontaminating; dissipative Microcon vinyl fabric features a surface resistivity of 5.3 x 10⁶ ohms/square for protection against ESD damage in sensitive environments (see static specifications below).
