The liquid enter into the container of the bag filter through side or bottom. Filter bag expand symmetrical in case of liquid wallop. The liquid will be out from bottom as well s the impurities stay in the filter bag. When the filter process has completed, the operator just loose the bolt and rotate the hand wheel to enhance the cover to remove filter bag, then clean or replace the filter bag.

Structure and working principle: the bag filter is a novel structure, small size, flexible and easy to operate, energy efficient, airtight work, the applicability of multi-purpose filtration equipment. The bag filter is a pressure filter device, a filter cylinder, filter cartridge cover and quick opening mechanism, stainless steel filter bag to strengthen the network and other major components, the filtrate from the filter housing flanking the entrance pipe flow into the filter bag, the bag itself is installed in strengthening the basket, liquid penetration through the required fineness grade bag is able to obtain qualified filtrate impurity particles intercept bag. Aircraft to replace the filter bag is very convenient, filtering the basic material consumption.
