Enclosure ventilation and moisture control in Aluminium & Stainless Steel

Breathable vent plugs manufactured in Aluminium or Stainless Steel offer reliable pressure equalisation to prevent condensation inside sealed enclosures. By balancing internal and external pressure, they protect against moisture, corrosion, and short circuits, eliminating the need for costly heating or ventilation systems. Rated up to IP68 and featuring durable, breathable Acrylic copolymer on nylon-support membranes, these solutions enhance safety, extend service life, and reduce maintenance in harsh environments.

Use the Bimed VentCalculator to work out your required pressure compensation.
  • Designed to provide reliable pressure equalization inside sealed housings and enclosures
  • Prevents the formation of water condensation and protects against damage caused by pressure differences
  • Extends the service life of equipment by reducing stress on enclosure gaskets and seals
  • Provides effective protection against water, dust and contaminants while allowing controlled airflow
  • Manufactured from high-quality, corrosion-resistant stainless steel
  • Suitable for indoor, outdoor, and harsh industrial environments
  • Available in types that provide ventilation performance from very low to very high levels, depending on application needs
  • Offered with different mounting options, including threaded connection or snap-in installation
