  • Vents in high airflow to balance the pressure and lower down tension for sealing stripe.
  • With the hydrophobic and oleophobic membrane inserted inside the anodized aluminum body, the vent plug becomes chemically inner and UV-resistant.
  • Press-fit installation and the silica sealing ring can both help in enhancing the airtightness.
  • Good performance in lowering fog and condensation.
  • Long service life and free from maintenance even under harsh working environment.
  • The e-PTFE membrane prevents the permeability of salt crystals, salt fog and vapor.


  • Make sure the installation surface is clean and free of oil and other contaminants. As shown in the installation drawing, ventilation holes should be installed on flat, vertical surfaces for optimum performance.
