Pressure Compensation Seals

Pressure compensation seals consist of a waterproof and dust-proof but air-permeable membrane. This allows air exchange in enclosures and protects the electronics from moisture and dirt.


Pressure Compensation Seals for Venting

Temperature fluctuations occur frequently in the technical industry. Overpressure or underpressure caused by these can deform housings and lead to leakage. Pressure compensation seals provide pressure compensation and protect the housing and components. They are gas-permeable and water-tight at the same time.

The business unit Schreiner ProTech has been working with this proven technology for venting of housings since 1997. The membranes prevent pressure differences from occurring in a housing and thus increase the service life of electronic components.

Your Advantages at a Glance

  • Easy attachment by self-adhesive equipment or ultrasonic welding
  • High air flow rate for fast compensation of pressure differences
  • High water retention capacity
  • High flexibility in product design in terms of shape, size, material and adhesive
  • No change in housing geometry, due to mechanical fastening to the housing
  • Low overall height <0.5mm
  • Fabrication on roll for manual or automatic application 
  • Application-specific product validation
  • Project planning and implementation of processing and testing systems (from standard dispensing systems to complete manufacturing cells)
