1) The Installation hole size adopts the general standard of M16*1.5.
2) It is recommended to fix the cavity with nuts when the wall thickness of the cavity is less than 3mm.
3) When it needs to install two breathable valves, it’s suggested that the valves should be installed in opposite
directions to reach the air convection effects.
4) Suggested installation torque is 0.8N.m, lest torque too much to affect the product performance.
Changing harsh environmental conditions cause seals to fail and allow contaminants to damage sensitive electronics.
AYN® Screw-In Breathable Valve effectively equalize pressure and reduce condensation in sealed enclosures, while
keeping out solid and liquid contaminants. They improve the safety, reliability and service life of outdoor electronic
devices. AYN® Screw-In Breathable Valve is designed to provide Hydrophobic/Oleophobic protection and withstand the
mechanical stresses of challenging environments.
Shelf life is five years from the date of receipt for this product as long as this product is stored in its original packaging in
an environment below 80° F (27° C) and 60% RH.
All data above are typical data for the membrane raw material, for reference only, and should not be used as special data for outgoing quality control.
