Protective Vents for Electronic Enclosures
Electronic enclosures are vulnerable to a wide range of environmental hazards that can affect the performance, reliability and life expectancy of the sensitive electronics within.

Comprehensive Solution to:

  • Equalize pressure, to avert premature seal
When the enclosure is exposed to environmental temperature changes, or temperature changes related to the device turning on and off, a pressure differential is created between the enclosure air volume and the environment. These pressure changes put extreme stress on the housing seals, over time causing them to fail and allow moisture and other contaminants to enter. PorVent vents equalize pressure by allowing air to pass through the membrane.
  • Prevent contamination (Moisture, Wind driven rain & particulates and other contaminants)
A rapid change of temperature or altitude will cause pressure differentials between the enclosure and its environment. This leads to a vacuum forming within the enclosure. As the vacuum draws in contaminants, this will result in lower-performance, increased costs and dissatisfied customers. Porvent Vents provide a durable barrier against liquid, dust, dirt and other contaminants.
  • Reduce condensation that can corrode sensitive electronics
In addition to failed seals, moisture can get inside enclosures by diffusion – the process by which vapor moves by natural molecular motion through the walls of a polymer enclosure. When water vapor enters a sealed enclosure and has no way to escape, it will condense to a liquid state. If this condensation remains inside the sealed enclosure, it can compromise functions and corrode sensitive electronics and battery contacts. Independent research has shown that condensation is more damaging than rain because it remains on the surface. PorVent Vents reduce condensation because water vapor molecules can pass through the membrane.
  • Integrate easily with a compact venting structure
  • Extend lifetime of the product
  • Eliminate the need for ruggedized housings, reducing costs and weight
  • Meet industry standards


Current trends make preventing condensation in outdoor enclosures more important than ever. For example:
  • Unlike conventional lamps, LED lighting generates less heat, creating a cold spot at the lens that encourages humidity to build up into condensation. The LED benefits — energy efficiency and bulb life — can easily be cancelled out if condensation causes premature lamp failure, and more frequent, more costly maintenance calls or warranty claims.
  • As electronic devices of all types integrate more components and functions into smaller housings, they become more vulnerable to condensation-induced corrosion. At the same time, customers expect these higher-value assemblies will deliver more reliable performance over longer times.
To summarize, this membrane’s microstructure has pores small enough to block entry of water, fluids, dust, dirt, salts and other contaminants. Yet at the same time, these pores are large enough to allow molecules of air and gases — including humidity (moisture vapor) to exit the enclosure. This not only reduces the chance of condensation build-up, but also equalizes pressures that could otherwise stress enclosure seals to fail and admit even more moisture.
