Waterproof breathable valve

A waterproof and breathable valve is a special type of valve that can prevent moisture (such as rainwater, fog, water vapor, etc.) from entering the interior of equipment while allowing air to enter and exit freely.

Its structure typically includes key components such as a waterproof and breathable membrane. The waterproof and breathable membrane is a microporous membrane. The size of the micropores is carefully designed to enable gas molecules (such as oxygen, nitrogen, etc.) to pass through smoothly, while liquid water cannot penetrate these micropores due to the effect of surface tension. The outer shell part serves to protect and fix the breathable membrane, and at the same time, it is adaptively installed with the outer shell of the equipment.

It helps with heat dissipation. The breathable valve allows fresh air to enter the interior of the equipment and carry away heat. For some equipment with high heat - dissipation requirements, such as high - power LED lights, it can improve the heat - dissipation efficiency and extend the service life of the equipment.
