Ventilation, breathers/pressure equalizers and silencers

Four metal implants with textured surfaces on a white background.


relieves, allows pressure equalization at the same time excluding contaminants. Sound attenuation / reduction.

Different designs for different uses:

– valves
– Valve covers
– tank valves
– audio / speaker enclosures
– Mold valves
– Interest on rising pressure devices
– sound attenuation for pneumatic devices

Note: Media can be treated to repel water while maintaining permeability.
