The bag filter is easy to operate. When in use, simply place the filter bag with the required fineness level inside the filter cartridge, check if the O-ring seal is intact, and then tighten the ring bolt of the filter cartridge cover to put it into operation.

After the pump is started, the pressure gauge on the filter slightly rises, with an initial pressure of about 0.05MPa. As the usage time prolongs, the filter residue in the cylinder gradually increases. When the pressure reaches 0.4MPa, the machine should be stopped and the cylinder cover should be opened to check the residue condition of the filter bag. The filter bag can be changed and continued to be used (after cleaning, it can be reused).

The pressure of the filter is generally adjusted between 0.1 and 0.3 MPa, which is more suitable. It can be adjusted through the reflux pipeline or the reflux valve on the pump. Excessive filtration pressure can damage the filter bag and maintenance net, so special attention should be paid.
