Breather Material K - Plastic (Polyamide PA) (phasing out - available whilst stocks last)
Breather Material M - Stainless Steel AISI 304
GN882 Breather or Exhaust Filter
These breather filters, GN 882, are used when the air exchange is to be allowed between the inside of the container and the ambient air. The filter function is marked by a blue colour ring.
The filter prevents air-borne particles (e.g. dust) from being carried from the outside to the inside of the container. It also ensures that e.g. oil particles do not escape to the outside.
The above diagram shows the air passage as a factor of the differential pressure.
