The SMF series filter is composed of two single bowl filters, two check valves, directional valve and indicator. It fit the medium and low pressure hydraulic system.

The feature of this filter allows continues operation during replacing the element which is clogged by contaminant. By opening the balance valve and turning the direction valve, the other filter will be working, the clogged element should be changed at that time..

This series filter is widely used in the hydraulic systems of heavy-duty mining and metallurgical machines.

>>Feature:

1. It fit the medium and low pressure hydraulic system.
2. This filter allows continues operation during replacing the element which is clogged by contaminant
3. Alway on working unit it is break.
4. Simple structure, easy operation.

>>Operating steps:

1. Install the duplex filter to the working system.
2. Filter installation is completed , open the inlet and outlet valve of the filter , the system start to working.
3. When the CMS-I is alarm (differential pressure is achieved 0.35MPa), pls change the switch valve and let the spare filter to work.
4. Open the vent valve(on the upper cap) and blowdown valve (on the bottom cap), let the dust fluid drain off the filter completely.
5. Open the upper cap of filter, take our the filter element .
6. Clean or change the filter element , then install the filter element and upper cap.
7. Closed the vent valve and blow down valve and let this filter to be a spare filter to wait once again the replacement.

>>Matters need attention:

It must know the upper is inlet and below is outlet when installed .
1. It must to change filter cartridge in time when the CMS-I is alarm , and let the filter is in standby state .
2. Switch valve must be in place.
3. It need to ready the new filter cartridge when to change it , do the best to reduce the time of filter internal reveal.
4. Pay attention to the seals are ok or not when change the cartridge . Don’t omit the seals when installed.
5. Don’t let anything fall into the filter after open the cover.
