Ventilation plugs (also known as pressure balance elements) are membrane devices which are permeable to air, gases and vapour, and impermeable, or almost impermeable to water, liquids, and dust. The degree of permeability to liquids depends upon the size of the pores and structure of the membrane inside such devices.
Applications include:
-
-
- prevention of pressure increase inside an enclosure without risk of penetration of liquids
- prevention of accidental suction of liquids in an enclosure when its inside temperature decreases
- allowing air flow for ventilation
- improved maintenance criteria, since pressure buildup will not be present if the interior of an enclosure is hot, etc…

ITC offers a range of products including a range of metallic and non-metallic plugs, equipped with an acrylic co-polymer membrane, with different degrees of permeability (Standard, Medium, High, Ultra-High). The higher the degree of permeability, the lower the pressure at which liquid intrusion occurs.
Ventilation glands are also available, combining the functionality of both cable glands and ventilation plugs.
