RFA Return Oil Filter for Oil Tank High Precision Filter

(1)Introduction

The RFA (LHN) filter is suitable for the fine filtration of return oil in hydraulic systems. It can effectively filter out contaminants such as metal particles caused by component wear and rubber impurities shed from aging seals within the system, ensuring the cleanliness of the oil flowing back to the oil tank.

The RFA filter is installed on the top of the oil tank, with the cylinder part immersed in the interior of the oil tank. It is equipped with components such as a bypass valve, diffuser, and filter element contamination and clogging transmitter. It features a compact structure, convenient installation, large oil flow capacity, low pressure loss, and easy filter element replacement.OLYMPUS DIGITAL CAMERA
