Enclosure ventilation and moisture control in Plastic

Breathable vent plugs manufactured in Plastic Nylon PA6 UL94-V2 material 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.
