Splash proof function: A waterproof and breathable valve that can be used in environments with oil. 

Due to the damage of oil to the waterproof and breathable film, the breathable performance can be

 improved. If the waterproof and breathable valve can effectively prevent oil from splashing onto the 

film, it can better play the waterproof and breathable function of the film. For this consideration, our 

company has designed a splash proof waterproof and breathable valve.

The working diagram of the splash proof, waterproof, and breathable valve is as follows

When the equipment is in operation, the liquid inside the equipment will constantly shake and 

splash onto the waterproof breathable film inside the waterproof breathable valve, resulting in 

a significant loss of breathability of the breathable film

The curved design of the air flow channel prevents the liquid from 

splashing on the membrane during movement, thus ensuring smooth ventilation.
