A waterproof ventilation filter equipped with four functions that promise the longevity and safety of the battery pack system.
1. Protection from liquids such as water and oil, as well as contamination 2. Prevention of pressure fluctuations within the battery pack 3. Prevention of condensation inside the battery 4. Fail-safe mechanism to minimize damage to equipment and personnel due to battery abnormalities The battery vent uses Donaldson's uniquely developed Tetratex(R). Tetratex, a porous membrane with a finely structured PTFE that has been specially stretched, features a high porosity despite its very small pore size. In addition to oil resistance, chemical resistance, and heat resistance, it also excels in water repellency and oil repellency. The battery vent, securely welded to the housing with this high-performance material Tetratex, can prevent the intrusion of dust, oil, and moisture while maintaining breathability and equalization of pressure, thereby achieving enhanced battery performance and prolonging the lifespan of the equipment.
