Reduce condensation, prevent contamination, Equalize pressure, gas permeable, oleophobic , waterproof ,anti –dust

1.Because of the environmental temperature variations, fluctuations caused by electronics and lights , engine heat , frictions and water spray , Water and water vapor can enter enclosures from a variety of points including seals, cracks, breathers and even the plastic used in connectors and housings. If these pressures are not equalized or relieved, they create stress on the housing and seals that can cause cracks, condensation, leaks and seal failures that will eventually lead to water and contaminants entering the housing and device failure.

2.Automotive lighting vents which made by Micro-VENT  EPTFE  allow gas transmission while providing a reliable, long-lasting barrier from water, automotive fluids, dust and other contaminants in a variety of automotive part applications. Harsh automotive conditions require sealed protection for parts. Engine heat, friction and the extremes of environmental conditions make automotive applications some of the toughest in the world. To prevent the ingress of water, automotive fluids, dirt and dust vehicle devices need to be sealed. Changing temperatures can cause pressure differentials between the inside of the housing and the external environment.
