Gore^® Protective Vents vs. Common Venting Solutions

As the name says, Gore Protective Vents enable pressure equalization through venting with the key feature of ingress protection. Other venting technologies have limits to protecting against the ingress of dust and moisture.

Ingress Protection, IP, is an internationally accepted standard for indicating how well an electrical enclosure protects electronic equipment, devices, or components against solid objects and liquids.

This document shows the Installation Instructions and Instructions for Use of GORE PolyVent Ex. In addition the relevant standards are listed and the attestation of conformity is described.

A critical aspect of vent selection begins with defining the level of protection your application, device or housing requires.

IP ratings cannot be “converted” to NEMA ratings, since NEMA requires additional testing not included in IP. However, there are minimum NEMA ratings that will meet or exceed a given IP code.

This document explains the format and classification of Ingress Protection (IP) ratings, according to the IEC 60529 standards.

This document explains the Underwriters Laboratory standard for testing the flammability properties of plastic materials used for parts in devices and appliances.

The key to choosing the appropriate membrane technology for a given application is understanding the environmental conditions and the surface tension of the fluids that the vent will encounter.
