Vents for Renewable Energy Systems

Tougher and more durable protection vents for wind and solar systems

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 they allow the device to breathe during heating and cooling cycles. Our filters can be customized to filter fluid or air, depending on the application. With their sintered structure, the POREX Virtek vents assemble easily and can be handled and welded without the need for cumbersome assembly instructions.

In addition, Porex provides several venting and filtering solutions for your gearbox challenges. These venting and filtration solutions can vary—from simple self-adhesive protection vents, to vents containing media for specific moisture or fume absorption, to venting filters for separating oil mists. The materials are customizable to your specific gearbox venting application and can incorporate functional additives for optimized performance.

Key Features & Benefits

Compared with 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.
