TRF SUCTION AND RETURN FILTER SERIES

    The TRF series filter can be used in the closed loop hydraulic system, and can filter many kinds of contamination like metal granules or rubber impurities in order to keep the oil clean and prolong the service life of pump and other components.

    This filter has contamination cup in order to make the contamination removed to gether with the element and prevent the contamination from getting into the tank again when changing filter element.

    Please inject the oil to the system until full before the operation of the filter. Start the system and close the oil infusion valve, let the oil flow in the closed system. The filter has oil suction valve. If the system lacks oil because of leaking, the oil will be injected to the system through oil suction valve and oil suction element, so the system is enough supplied with oil. If the return oil in the system is too much, the relief valve at the bottom of the filter will open to let the oil flow back to the tank.
