high quality duplex high pressure filter,high equality hydraulic oil filter
The feature of duplex oil strainer allows for continuous operation when changing elements due to clogging caused by contaminants. After opening the balance valve and turning the directional valve, the other filter begins to work, thus a clogged element should be changed in time.
These series of duplex basket strainer have a high flow range from 1300 l/min to 15000 l/min with maximum pressure 1.6 Mpa. They are widely used in the hydraulic systems of heavy-duty mining and metallurgical machines.
Note: As the leading duplex strainer manufacturer in China , Lilt filter can custom any duplex basket strainers based your detailed requirement.
Operating Steps of Novel Design Large Flow Oil Duplex Filter/Hydraulic Oil Return Line Filter/Twin Strainer for Industry & Business
1. Install the duplex basket filter in the working system.
2. After completing filter installation, open the inlet and outlet valves of the filter; the system will start working.
3. When the CMS-I alarm turns on (differential pressure is achieved 0.35MPa), please change the switch valve and let the spare filter work.
4. Open the vent valve (on the upper cap) and blow-down valve (on the bottom cap); let the dust fluid drain off the filter completely.
5. Open its upper can and take out the filter element.
6. Clean or change the filter element, then install the filter element and upper cap.
7. Close the vent valve and blow-down valve. Make it a spare filter you can use once again for replacement.

Notice of Golden Supplier high quality duplex high pressure filter,high equality hydraulic oil filter
You must know the exact positions of our duplex strainer – upper is the inlet and lower is an outlet after installation.
1. Change the filter cartridges in time when the CMS-I alarm is on and let the filter be in standby state.
2. Switch valve must be in place.
3. Have the new filter cartridge ready and know when to change it. Reduce the time interval when the internal components of the filter are exposed.
4. Ensure the seals are in good-working condition whenever you change the cartridge. Don’t forget to put the seals during installation.
5. Don’t let anything fall into the filter after opening the cover.
