The hydraulic filter traps dirt as oil moves through it. The filter element can catch very tiny pieces, even one micron in size. This means even the smallest dirt cannot get by. Most filters use special stuff like glass fiber fleece, polyester, cellulose, or stainless steel wire mesh. These materials help the filter grab and hold dirt. The filter element has a support tube and end caps to keep it strong.
Tip: Always look at your filter’s micron rating. A lower micron number means it catches smaller dirt, so your machine gets better protection.
Types of Hydraulic Filter
There are different hydraulic filters for different machines and jobs. Each type works best in a certain spot in the hydraulic system. Here are some common types of hydraulic filters:
Suction Filters: You put these at the pump’s inlet. They catch big pieces before they go into the pump.
Pressure Filters: These go after the pump. They protect important parts by catching small dirt under high pressure.
Return Line Filters: You use these on the return line. They clean oil before it goes back to the tank.
Breather Filters: These stop dust and dirt from getting in through air vents.
Filter Type | Where You Use It | Main Purpose |
|---|---|---|
Suction Filter | Pump Inlet | Stops big debris |
Pressure Filter | After Pump | Protects important parts |
