Screw-in breather GTA-PC series

vertical

Summary
A screw-in pressure-compensation breather designed to allow air and water vapor to pass while equalizing pressure between the interior and exterior of sealed cabinets and enclosures.

Features

• Physical: Nut fixing. GTA-PC12 and GTA-PC40 in light grey; GTA-PC38 in beige. Protection rating IP55 when mounted vertically (GTA-PC38) or IP54 when mounted otherwise.
• Protection rating: Variants available up to IP67 depending on model.

Benefits

• Reduces condensation formation.
• Prevents internal overpressure and underpressure.
• Maintains enclosure sealing while enabling pressure equalization.

Functions / Applications
These screw-in pressure-compensation fittings (depressurization breathers) are used in electrical cabinets, sealed enclosures and electronic housings to equalize pressure between inside and outside. They allow air and water vapor to escape while limiting ingress of water and dust. By reducing condensation due to temperature variations, they help preserve the sealing and reliability of electrical and electronic equipment.
