  • About enclosure vent discs

    Enclosure vent discs play a vital role in the management of temperature, humidity, gases and pressure, and the prevention of liquid, dust and chemical contamination.

    We offer a range of enclosure vent discs in Porex PMV15, PMV20 and PMV30 materials. In addition, we can produce parts to your exact specification, be it for a custom width roll, into sheets or as custom shapes, from any vent membrane material.

    We can also advise on the optimum venting material for your application and offer a broad range of material combinations through our partnerships with a wide range of world leading material manufacturers.
