Bypass oil filtration systems
Our bypass systems ensure a perfect filtration of oils at high and low pressure
Advantages of bypass filtration
This filtration is installed in bypass using the flow and pressure of the system.
- The constant filtration, whilst the system is operating, cleans the entire system, and not just the oil in the tank.
- For peace of mind after the installation – just change the filter element as part of the routine maintenance.
