Plastic pressure compensation device APCDABS

Product overview
Pressure differentials in a tightly sealed enclosure result from heat generated by electrical and electronic equipment inside the enclosure and from outside ambient temperature fluctuations. This pressure compensation plug enables slow pressure equalization while maintaining dust and water protection; when correctly installed it preserves IP66 protection. For optimal performance, install two plugs diagonally to each other.

Features

• Air permeability: 42 ft³/h (1,200 L/h) at a pressure difference ≥70 mbar
• Easy installation: drill a 1.60 in (41 mm) diameter hole
• Sealing gasket: Nitrile (Buna‑N) rubber
• Semipermeable membrane inside the plug filters moisture and dust
• Mounting thread: M40 with union nut
