For over 50 years, the MANN+HUMMEL centrifugal oil cleaners have proved to be the key factor in reducing component wear while increasing the oil and engine life cycle.

In close collaboration with MANN+HUMMEL, Detroit Diesel/MTU, like other OEMs, have significantly extended oil drain intervals on their 4000-series engines.

We are world leaders in the field of by-pass oil conditioning systems and have over the years established a large customer base in the marine and power generation market.
