Bypass Filtration Systems

Permanently installed bypass filtration using the flow and pressure of the system that is being filtered. Particles and moisture are removed leaving oil “cleaner than new”*, whilst reducing downtime and component wear.

All CARDEV bypass filtration is covered by our lifetime warranty *

Lifetime Warranty Terms

Return a damaged bypass filtration system and we will repair or replace it without charge. (Lifetime warranty is non-transferable, does not cover replacement filter elements, and applies only if equipment is correctly installed/used).
