The air filter replacement cycle has theoretical calculations, but in actual operation, operability is not strong and can only be replaced based on experience. Filter replacement cycle, see table below (for reference only): category Check content Replacement cycle Fresh air inlet filter Is the mesh more than half blocked? Sweep about once a week Coarse filter The resistance has exceeded the rated initial resistance of about 60Pa , or equal to 2 × the initial resistance of the design or operation 1-2 months Medium efficiency filter The resistance has exceeded the rated initial resistance of about 80Pa , or equal to 2 × the initial resistance of the design or operation 2-4 months Sub-high efficiency filter The resistance has exceeded the rated initial resistance of about 100Pa , or equal to 2 × the design or the initial resistance during the operation (low resistance and sub-effectiveness is 3 times) 1 year or more High efficiency filter The resistance has exceeded the rated initial resistance of around 160Pa , or equal to 2 × the initial resistance of the design or operation 3 years or more Low-efficiency filters generally use coarse fiber filters. The gaps between the fibers are large. Excessive resistance may cause the dust on the filter to blow away. In this case, the filter resistance will no longer increase, but the filtration efficiency will be reduced to almost It is zero, so we must strictly control the final resistance value of the rough filter! Guangzhou Hao Tai purification provide This product [500t Cement Silos" is adopt chip-mounted cement silo is specially designed and developed for the difficulty of packing and the high transportation cost. The top of the warehouse is equipped with a pressure relief valve to balance the pressure inside the chamber. Prevent explosions. Each cement silo is provided with an upper and lower material level indicator, which can display the empty state of the silo. 500 Ton Cement Silo,500T Concrete Cement Silo,500T Cement Silos,500T Bolted Cement Silo Shandong Zeyu Heavy Industry Science and Technology Co.,Ltd. , https://www.zeyumixer.com
