Unit Design


As a By Pass : the Kleenoil takes a small feed so as not to affect pressures, and cleans it slowly and so finely, whilst the full flow filter remains in use.


The unit is mounted in a position suitable for ease of access when changing the replacement cartridge, and where pipe lengths are kept to a minimum., Whether it be on engine or machine.


An aluminum cast unit available in a variety of sizes appropriate to its use. Castings subjected to batch and indi-vidual testing constructed of Aluminum BS1490 LM6 (M)

Hydraulic Application


The PRV Modules can be installed to hydraulic systems, compressors, or any system with oil at pressure up to 3000PSI.

The flow through the Kleenoil Filter is controlled to approximately 4 ltrs / minute at 40 PSI. to give a flow rate low enough to offer negligible effects on most 'System Pressures', Yet high enough to ensure that oil is being kept in 'as new' condition.

Filtration Level: Particulate contamination in accordance with BS 5540 Part 4: 1981 and ISO/DIS 4406 14/9, equivalent to NAS 1638 Class 6 (Hydraulic Oil Specification).

Water Retention: To <0.025%

NAS GRADE (National Aerospace Standard 1638)


Code SDU9788KU85 Super duty Filter Unit



The Kleenoil Bypass Filter System is a bypass oil filtration system that passes only a small portion of the total oil flow through a very dense filter cartridge.

At a slow speed, it is possible to remove particles down to 1 micron (3 absolute), remove 99.95% of all water, greatly decrease engine wear and prolong oil life.

Kleenoil can eliminate water and particle contamination, extend oil life up to 5 times and hydraulic oil up to 10 times, reduce engine/machine wear and component wear, dramatically reduce downtime, and is applicable to engines as well as hydraulic systems
