What are the selection methods for return oil filter?

The function of the oil return filter is to filter out the pollutants produced or invaded in the system before returning to the oil tank. 

Therefore, the return oil filter is one of the most important filters to control the pollution cleanliness of the system. 

So how do you choose an oil return filter?


The selection of return oil filter is as follows:

1. When choosing an oil return filter, first choose one with high pressure and a large number of steel wire layers based on the pressure

of the system. Each oil pipe has a maximum working pressure, and the rupture pressure is 4 times the maximum working pressure.


2. Pay attention to its bending radius when selecting. When calculating the bend radius, the crimp length of the front fitting should be 

subtracted. If the installed bending radius is too small, it will reduce its pressure-bearing capacity and affect its service life.


3. Select the inner diameter of the oil pipe according to the flow rate. If the pipe diameter is too small, the flow rate of the medium in the

 pipe will increase, causing the system to heat up and produce an excessive pressure drop, thus affecting the performance of the entire system.


The oil return filter is one of the most important filters to control the pollution cleanliness of the system. The function of the oil return filter 

is to filter out the pollutants produced or invaded in the system before returning to the fuel tank. When we all choose the oil return filter,

 we can follow the above selection. This type of oil return filter is what we all need to choose.
