What is the effect of the bypass valve on the compressed air filter? In the compressed air system,The filter is installed at the back end of the tank and in front of the dryer.Generally,When installing the filter,People will install bypass valves at the top of the filter.Why install the bypass valve?The role of installing the bypass valve at the upper end of the compressed air filter is when replacing or cleaning the filter,While closing the isolation valve,Open the bypass valve to ensure the gas supply demand and normal operation of the machine.1. open the bypass valve,Close the isolation valve at both ends,Isolate the filter from the compressed air system;2. open the vent valve,Reduce the pressure inside the compressed air filter to atmospheric pressure.Remove the manual or automatic drain valve;3. loosen each screw on the top edge of the upper cover to the extent that the two-stage filtration device can move freely,Remove two diagonal screws,Remove the old filter.Take out the star-shaped Packer fro

What are the folding filter material? First, the common material of folding filter membrane is generally divided into: PP (polypropylene ),PES (PES ),PTFE (PTFE ),(Poly-difluoride) and N6 nylon.The pressure difference is low, the pollution removal capacity is strong, and the chemical compatibility is wide,Low cost of use,It can be used for various medium and high efficiency air filtration and pre-filtration of water treatment The filter accuracy range can be from 0.1 μm to 60 μm.The sealing of the end cap of the filter element and the overall structural connection are all made of hot melt bonding.The filter element joints are three types commonly used in the world: 222 joints, 226 joints and flat ports.The products have been strictly tested before leaving the factory,To ensure stable performance of the product.Favored by the majority of users.It has good high temperature resistance, acid and alkali resistance,The membrane is hydrophilic,Large flux and uniform pore size distribution;No media fallin
