Production Introduction

RF series direct return oil filter lefilter

RF series direct return oil filter

The filter is used for fine filtration of the return oil of the hydraulic system to filter out metal particles produced by the wear of components in the hydraulic system and rubber impurities of seals and other pollutants,so as to keep the oil flowing back to the oil tank clean.

Application widely used in hydraulic systems such as heavy machinery, mining machinery and metallurgical machinery.

Performance and Characteristics

1、The filter can be installed directly on the cover of the oil tank,or by pipe. 

2、It is equipped with filter element pollution blocking transmitter and by-pass valve,which can improve the reliability of hydraulic system.when the filter element is blocked by pollutants or the oil inlet pressure is 0.35Mpa due to low system liquid temperature,flow pulsation and other factors,the transmitter will send a signal indicating that the filter element should be replaced or the temperature should be increased in time.If the machine cannot be shut down immediately to deal with these faults at this time,the by-pass valve on the filter element will open automatically (the opening pressure difference is 0.4MPa).

3、The filter element is made of chemical fiber,which has the advantages of high filtration accuracy,large oil passing capacity,small original pressure loss,high pollutant carrying capacity and so on.The filtration accuracy is calibrated by absolute filtration accuracy,the filtration ratioβ3,5,10,20≥200, filtration efficiency N≥99.5%, in line with ISO standards.
