1.Material:stainlesssteel, carbon filter;

2.Application:This filter is widely used in metallurgical machinery , mining machinery ,heavy-duty machinery etc hydraulic system;

3.Structure:Switching valves(1 piece);

pressure gauges(2pcs);

Differentialpressure transducer(1 piece);

Housing andfilter element(2pcs);

Balanced valve(1 piece);

gasketand O-ring(2sizes ,2pcs);

asbestospad(2pcs);

flatgasket,bolts and nuts(16sets);

4.Workingprinciple: There is onlyone filter to operation in normally work . You can not stop the system then openthe pressure balance valve and roll reversing vales .switch to another filter towork , when the filter pressure loss exceed(more than 0.35 MPa ) and then cleanor replace the filter element.

1.Filter installation is completed , open the inlet and outlet valve of the filter, the system start to working;

2.When the differential pressure transducer is alarm (differential pressure isachieved 0.35MPa), pls change the conversion valve and let another filter towork;

3.Open the vent valve(on the upper cap) and blowdown valve (on the bottom cap),let the dust fluid drain off the filter completely;

4.Open the upper cap of filter , take our the filter element;

5.Clean or change the filter element , then install the filter element and uppercap;

6.Closed the vent valve and blowdown valve and open the inlet and outlet valve ofthe filter;

7. Thebest advantage of the duplex filter is when the element need to change or clean, don't need stop system working.
