SRFA double barrel direct return oil filter

Product details

SRFA double barrel direct return oil filter is composed of two one-way filters, reversing valve, bypass valve, transmitter, diffuser and so on. It is installed on the top of the tank, can be replaced in the system without stopping the filter element, suitable for continuous work hydraulic system oil fine filtration, used to filter out the hydraulic system components wear metal powder and seal rubber impurities, so that the flow back to the tank of oil to keep clean, in order to facilitate the system of oil circulation.

When the filter element of a filter is blocked so that the inlet and outlet pressure difference is 0.35MPa, the transmitter sends a signal. At this time, the reversing valve is turned to make the standby oil filter work, and then the blocked filter element is replaced.

When the blocked filter element cannot be replaced in time for some reason, so that the pressure difference of the inlet and outlet further rises to 0.4MPa, the bypass valve automatically starts to work, so as to protect the filter element and the system working normally, but the user should replace the filter element as soon as possible.

Product advantage

Because the design adopts the direct return filter oil, it is convenient to replace the filter element or fuel the tank. The double barrel filter can be replaced by just unscrew the filter or fuel the tank. Each filter head is provided with two M18X1.5 oil ports, and the transmitter can be installed at any place. The diffuser is set at the point of the oil return cylinder, which can make the oil return medium flow smoothly into the tank, not easy to produce bubbles, reduce the re-entry of air, and weaken the disturbance that has been deposited pollution. The filter element is made of new chemical fiber filter material, which has the advantages of high filtration degree, large oil passing capacity, small original pressure loss, pollution carrying capacity, etc., filtration ratio β3.5, 10, 20>100, filtration efficiency n≥99%, in line with ISO standards.
