Applications
CCHN air vent plugs can be widely used in battery packs and battery boxes of base station equipment, new energy electric vehicles, hybrid vehicles, the solar energy industry, high-power energy storage equipment, and various outdoor electrical equipment products.

Tips: Functions of the Vent Plug
-
Dustproof: The vent plug prevents dust and other solid particles from entering the system, keeping internal components clean and protected.
-
Hydrophobic: It repels water and moisture, stopping liquids from penetrating while still allowing air to pass through.
-
Breathable: The breathable vent plug allows air and gases to flow in and out, balancing internal pressure and preventing vacuum or overpressure conditions.
-
Heat Dissipation: By enabling airflow, it helps dissipate heat from enclosed spaces, preventing overheating and maintaining optimal operating temperatures.
