The DeWAL V-Series venting membranes capitalize on the unique microstructure of ePTFE (expanded polytetrafluoroethylene), allowing continuous pressure equalization while maintaining an environmental seal. These unique membranes allow gas and vapor molecules to pass through easily while ensuring that liquid and other contaminants are repelled. These features help prevent vents from closing, putting less stress on the seal and improving the long-term reliability of enclosures.

Features

  • Semi-permeable membrane, naturally hydrophobic
  • Exceptional chemical resistance
  • Low coefficient of friction
  • Available in ePTFE or ePTFE-laminated options.

Benefits

  • Allows air to equalize while sealing from water
  • Water beading flows off and does not absorb
  • Protective from dirt, dust and debris
