Shanghai Kaisen Environmental Protection and China University of Petroleum have forged a strategic collaboration to pioneer an Oleophobic Waterproof Oil-Filtering Breathable Valve, designed for protective systems in various oil-cooled drive units of new energy applications. The Kaisen valve integrates nano-scale oleophobic fibers and a high-efficiency waterproof breathable membrane, achieving over 99.99% filtration efficiency for 1μm oil aerosol particles. With exceptional low-resistance performance and extended lifespan, this 100% in-house developed and manufactured innovation breaks foreign technological monopolies in critical components.

Shanghai Kaisen Environmental Protection's waterproof breathable membrane employs a self-developed material formula and proprietary stretching process to produce ePTFE membranes with billions of micropores per square centimeter. The pore diameter is 700 times larger than air molecules, yet 40,000 times smaller than external contaminants like water and dust. This engineered structure ensures unimpeded air/heat transfer while effectively mitigating condensation buildup, safeguarding equipment and products from operational failures.

Shanghai Kaisen Environmental Protection's waterproof breathable valve delivers exceptional protection against water and dust ingress while maintaining real-time pressure equilibrium between internal and external environments. Widely adopted in new energy systems, it provides critical safeguarding for motors, motor controllers, battery management systems (BMS), on-board chargers (OBC), and LiDAR protection systems.
