Ex Air Vent Plug Breather and Drainage Valves IP66

Description

Automatic drainage and breather valves are suitable to be used on increased safety, intrinsically safety or watertight enclosures to facilitate the elimination of condensation or vapors developed inside. Thanks to a precise mechanism, it is possible to obtain a continuous drainage and breathing of the junction box, protecting it from the possible formations of internal condensation and thus avoiding the periodic manual discharge, while ensuring a suitable IP degree of protection.
We recomended minimun 2 units per enclosure

is design for venting air and preventing water intake. Through it excellent permeability, Screw-in Vents balance the air pressure difference between inside of housing and environmental condition and low the pressure on seal gaskets, therefore it prolongs seal gaskets service life and improve the reliability of the device.The micro-pore membrane structure build-in Screw-in Vent provides an effective barrier from dust and dirt and still allows the product to breathe with changing environmental conditions. This prevents pressure from building up and damaging enclosure seals,exposing sensitive components to water and debris.Equipment used in the telecommunications industry is subjected to rapid temperature fluctuations, a variety of particulates, and exposure to wind, precipitation and solar radiation. Screw-in Vents effectively protect them against the negative effects of pressure differentials caused by temperature changes and provide an effective barrier against dust, water, salts and other corrosive liquids. 
Especially Its threaded design ensures secure mechanical fastening, its durable designs keep it able to used in extremely harsh environments in the field. Its unique property makes it find the wide application in shipboard telecommunication and alarm system.
