RFA Series Micro Direct Return Oil Filter

This filter is used for fine filtration of hydraulic system return oil, filtering out metal particles generated by wear of components in the hydraulic system and rubber impurities of seals and other pollutants, so that the oil flowing back to the oil tank remains clean.

Product Introduction

(I) Introduction

This filter is installed on the top of the oil tank, and the cylinder part is diffused into the oil tank, and is equipped with bypass valve, diffuser, filter element pollution blockage transmitter and other devices. It has the characteristics of compact structure, convenient installation, large oil flow capacity, small pressure loss, and convenient replacement of filter elements.

(II) Performance characteristics

1. Easy installation and connection, simplified system pipeline: This filter is directly installed on the oil tank cover, the filter head is exposed outside the oil tank, the return oil cylinder is immersed in the oil tank, and the oil inlet is provided with pipe and flange connections, thereby simplifying the system pipeline, making the system layout more compact and more convenient for installation and connection.

2. Set up filter element pollution transmitter and oil bypass valve to improve the reliability of hydraulic system: when the filter element is blocked by pollutants or the system fluid temperature is too low, flow pulsation and other factors cause the oil inlet pressure to be 0.35MP6, the transmitter will send a signal indication. The filter element should be replaced in time or the oil temperature should be increased. If it is not possible to stop the machine immediately to deal with these faults, the bypass valve located at the bottom of the filter element will automatically open (the bypass valve opening pressure is 0.4MPá) to protect the normal operation of the filter and hydraulic system.

3. The design adopts direct return oil filtration, which makes it very convenient to replace the filter element or add oil to the tank: you only need to unscrew the filter cover (cleaning cover) to replace the filter element or add oil to the tank, and there are 2 M18x1.5 oil ports on the filter head, which can be installed on either side of the transmitter or a small amount of oil in the system can be returned to the tank for filtration.

4. With liquid diffuser:

The diffuser is set at the bottom of the oil return cylinder, which can make the return oil medium flow smoothly into the oil tank, and it is not easy to generate bubbles, thereby reducing the re-entry of air and weakening the disturbance of deposited pollutants.

5. The filter element is made of glass fiber filter material: it has the advantages of high filtration accuracy, large oil flow capacity, small original pressure loss, and large pollution holding capacity. Its filtration accuracy is calibrated with absolute filtration accuracy, filtration ratio β3, 5.10.20>100, filtration efficiency n>99%, in line with IS0 standards.
