Frequently Asked Questions

A bypass filter processes a small amount of oil at a time, slowly passing it through high-density filtration media for deeper cleaning. Unlike full-flow filters, which prioritize speed and volume, bypass filters remove finer particles and water without interrupting system flow.

KLEENOIL filters down to 3 microns and achieves cleanliness levels better than ISO 18/16/13, exceeding typical OEM filtration.

Yes. KLEENOIL removes up to 99.5% of free and emulsified water, preventing corrosion and oil degradation.

No. It retains essential additives while removing harmful contaminants like dirt, soot, and water.

Typically every 500 hours or annually, depending on contamination levels.

Yes. It can be installed on new and existing systems including engines, hydraulics, and fuel tanks. OEM warranties may vary, but KLEENOIL has had no claims in 30+ years.

Yes. Suitable for small engines, industrial machinery, marine vessels, buses, and heavy equipment.

Portable units are mobile and flexible. Permanent systems are installed for continuous filtration.

There is no functional difference except labeling. KLEENOIL systems can be used for fuel filtration as well.

ELAIS is a modern portable filtration system with enhanced usability and mobility, ideal for fieldwork and compact systems.

Operates on 110V–240V, 415V, or 12V/24V (ELAIS).

Yes. Installation is simple with basic tools, and support is available.

Use oil sampling, lab analysis, ISO codes, or particle counters.

Better than ISO 18/16/13, exceeding new oil standards.

Yes. They complement OEM filters and help extend component life.

Extends oil life up to 5x–10x, reducing waste and emissions.

Typically 50–90% reduction in oil usage, depending on application.
