Advantages of Various Filters Used in a Hydraulic System
Depending on the configuration of the hydraulic system in use, there can be several different filters used. Most of these filters are designed to remove impurities from the hydraulic fluid and keep it at an acceptable level.
1. Air Filter
A good-quality air filter will help keep contaminants out of the reservoir. Some systems also use a secondary air filter to remove contaminants from the air within the actual reservoir.
2. Return Line Filter
A return line filter removes impurities from the fluid as it re-enters the fluid reservoir. This is a low-cost and effective way to ensure that all the fluid returning to the reservoir is clean.
3. Auxiliary (Off-Line) Filter
This is where the fluid is filtered outside the main system. Fluid is pumped from the reservoir through the filter and back into the reservoir. This is an effective way to help further clean the fluid while reducing the risks of potential side-effects of filtration within the main system.
4. Pressure Filter
Pressure filters are designed to help filter fluid whilst under pressure.
5. Pump Intake Filter
This filter is located where the fluid is drawn into the system. The filters used here must be the right size. Otherwise, restrictions to flow can occur, which can cause pump cavitation, oil breakdown and damage to other components.
