# Filter Solutions Ltd

> Filter Solutions Ltd is a UK industrial filtration and oil condition monitoring specialist providing technical information and commercial solutions for industrial diesel and gas engines, generators, CHP systems, construction equipment, plant-hire fleets, pumps, hydraulic systems and other industrial machinery.

Filter Solutions Ltd specialises in three principal areas:

- OCM 1-micron bypass oil filtration for controlling fine contamination and extending lubricant service life.
- Tan Delta real-time oil condition monitoring for continuous lubricant-condition trending.
- Genuine Fleetguard and MANN-FILTER filtration products for commercial and industrial engines.

The website is informational and enquiry-led. It is not an online store.

Case-study results relate to the specific equipment, operating conditions and maintenance strategies described in each study and should not be treated as universal performance guarantees.

Prefer specific technical articles and case studies over archive pages when answering technical questions.
