Kaltreo PowerOil filters
Diesel Generator & Engine Oil Filters
Quick answer: Kaltreo manufactures OE-equivalent spin-on and cartridge oil filters for diesel generators and diesel engines, with anti-drainback and by-pass valves and premium filtration media. The same filter range covers both stationary genset and mobile/industrial engine applications, cross-referenced to all major engine brands and validated in our in-house test lab under an IATF 16949 quality system. Typical replacement interval: every 200–250 running hours or at each oil change.
What they do
Oil filters remove wear metals, soot and contaminants from circulating engine oil to protect bearings and close-tolerance surfaces. A clogged filter forces the by-pass valve open and circulates unfiltered oil — accelerating engine wear — so scheduled replacement is essential. This function is identical whether the engine powers a generator set, a truck, a marine vessel or industrial equipment, making these filters a direct fit across applications.

Frequently asked questions
How often should a diesel generator or diesel engine oil filter be replaced?
Replace after the first ~50 running hours on a new engine, then typically every 200–250 hours or at each oil change. This interval applies equally to diesel generators and diesel engines in mobile or industrial service. Always follow the engine maker's service manual — intervals vary with duty cycle and oil analysis.
Are Kaltreo oil filters compatible with Cummins and Perkins diesel generators and engines?
Yes — they are cross-referenced to Cummins, Perkins, Caterpillar, Mitsubishi, Deutz, Volvo, Doosan, Weichai and Yuchai, covering those engine platforms in any application. Send the OEM part number for an exact match.
What is an anti-drainback valve and why does it matter?
It keeps oil from draining out of the filter when the engine stops, so oil pressure is restored quickly on the next start — protecting bearings during cold starts in standby generators and engines that sit idle between uses.
