Keep your wind and solar systems running efficiently
Protection vents and filters from Porex help renewable energy systems run more reliably. Our vents repel water, dust and dirt, and allows the device to breathe during heating and cooling cycles. Our filters can be customized to filter fluid or air, depending on the application.
Compared to competitive vents, our POREX Virtek® PTFE protection vents for wind and solar applications are:
- Tougher and more durable – POREX Virtek sintered PTFE material is able to withstand more handling without damage vs. expanded PTFE.
- Easily welded to plastic housings for more secure bonding, which minimizes leaks.
- Customizable to your application specifications, including shape and performance.

System Protection Vents
Keep your systems running smoothly in any weather
Porex Virtek protection vents for wind and solar applications are designed to keep systems running smoothly and effectively in any climate or weather condition.
With their sintered structure, the POREX Virtek vents assemble easily and can be handled and welded without the need for cumbersome assembly instructions.
Our protection vents for wind and solar applications:
- Equalize pressure – Reduce pressure build-up and allow heat to escape the enclosure because the air-permeable structure acts as a pressure-relief valve and protects the enclosure seals from premature failure.
- Protect from contaminants – Material repels water, dirt, oils and other liquids from entering the enclosure.
