Permanently maintain machine hydraulic oil to ‘as new’

KLEENOIL is an oil & diesel filtration technology.

Not only removes solid particles but absorbs water in one application. It also eliminates varnish, sludge and other oxidation by-products.

KLEENOIL – Trusted Worldwide for 50 Years in Oil Filtration

As the original manufacturer of the Kleenoil Bypass Filter System, we’ve spent five decades helping industries around the world solve oil contamination problems caused by dirt and water.

From diesel engines and hydraulic systems to gearboxes and industrial machinery, KLEENOIL systems are engineered to extend oil life, reduce wear, and improve machine hygiene—delivering significant savings in downtime, maintenance, and waste.

About KLEENOIL

The Kleenoil Bypass Filter System – Clean Oil. Longer Life. Maximum Protection.

The Kleenoil Bypass Filter System offers unrivalled oil and fuel filtration performance in a simple, efficient solution. It slowly diverts a small portion of oil or fuel through a high-density natural cellulose depth filter, achieving exceptional contaminant removal.

With each cycle, the system:

Why Clean Oil Matters

Prevents water and particle contamination
Extends oil life and reduces the need for top-ups
Prolongs the life of OEM filters and system components
Extends engine oil life by up to 5x and hydraulic oil by up to 10x
Cuts downtime, maintenance costs, and oil waste

Leading the Shift to Predictive Maintenance

Today’s maintenance practices have evolved—from reactive to preventative and predictive.
KLEENOIL enables this evolution with field-proven filtration technology that continuously removes solid particles and water from mineral oils, lubricants, and diesel fuels.

Whether you operate mobile fleets, heavy industry, manufacturing plants, or agricultural equipment, KLEENOIL helps your machines run longer, cleaner, and more cost-effectively.
