Waterproof breathable dust valve with electronic devices known as vitamin life. Recently, reporters from Technology Co., Ltd. Shenzhen Weixi learned Weixi technology co-operation between universities and companies, selected international brands of raw materials, domestic R & D to produce a new generation of dust ventilation valve, quality reaches the level of similar foreign products, but the price is half of similar products abroad. According to reports, Weixi Technologies developed waterproof breathable dust valve, using microporous expanded polytetrafluoroethylene ePTFE polymer film, which is a able to breath, breathable membrane filter - it allows gases through, while Meanwhile, water, oil, dust and other contaminants to provide a reliable long-term block. Exposed to outdoor environment for the equipment and products, waterproof breathable dust valve can provide effective protection against dust, water barriers, long service life in extreme environments and trouble-free maintenance, allowing equipment with better cooling effect. The product quality is to achieve the standards of similar foreign products, and the price is only half of similar products abroad. Currently, breathable waterproof and dustproof Weixi valve technology has been mass production, assembly design and other related patents pending.
