How Waterproof Breathable Vents Work
A waterproof breathable vent uses a specially designed membrane structure that allows air and moisture vapor to pass while blocking liquid water.
The microscopic pores of ePTFE membranes are smaller than water droplets but large enough for air molecules, creating a balance between protection and ventilation.
This technology helps reduce condensation, maintain pressure balance and improve product service life.
