characteristic:

 1. As long as the simple rotary handle is used, the filter mesh can be cleaned in the machine even when it is under pressure, and at the same time, the   machine and parts can continue to operate without interruption. There is no need to worry about the reduction of oil delivery by filtration.

 2. The filter surface will not be bent and deformed under the pressure back pressure. It is firm and reliable, exquisite and precise, with large filtering area and   excellent performance.

 3. There is no lack of metal mesh and cloth woven filter, no fault, and it can be used for a long time.

 4. It can be used as the circulation and reduction device of mechanical and mechanical pipes.

 5. It is necessary for safe operation and improvement of functional efficiency, with high installation efficiency. It is a foolproof automatic filter.

 6. With negative pressure gauge (new type), it can directly reflect whether the oil is smooth or not.
