ISO 14644-1 / ISO Class 2 (mit Einschränkung/ with limitation)
US FED 209E / US Class -
/ It must be pointed out, that according to ISO 14644-1 cleanrooms classes 1 to 5 have a high number of filters, which makes the use of absorber elements partly impossible.
/ Surfaces and edges may not become damaged during assembly because this would also have a negative influence on the particle emission behavior of the absorber elements when in later use.
/ Due to the porous surface and type of material utilized, which is only partially resistant to common cleaning agents, the absorber elements can only be cleaned to a limited extent in a cleanroom-suitable manner.
