operational process:

 

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 is achieved 0.35MPa), pls change the conversion valve and let another filter to work.

 

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 .
