Hydraulic Filter Unit

The Kleenoil "high pressure" oil filter can be fitted on the "by pass" basis to all hydraulic systems, compressors, or any other system with oil at pressure up to 3000psi.

The flow through the Kleenoil filter is controlled to approx. 4ltrs per minute at 40psi. A flow rate which is low enough to have negligible effect on most "system pressures", yet high enough to provide good quality filtration and ensure that oil is being kept in "as new" condition.

• Removes contaminant particles down to 1 micron
• Absorbs water content.
• Prevents corrosion of components
• Reduces component wear (seals, piston rods, pumps etc.)
• Reduces the incidence of sticking & worn value components
• Extends life of in-line OEM filters and components.
• End to the need to change hydraulic fluids
• All properties of oil being cleaned are maintained
• Filter cartridge can be changed within minutes.
• Can easily be removed and re-installed on replacement equipment
• Simple to install
• Used in transport and industry world-wide
• Can be used with virtually any petroleum/synthetic based oil
• Greatly reduced collection of waste oil by disposal companies

Pressure Limiting Valve

The Hydraulic Block is mounted to the bottom of the Kleenoil Bypass Filtration Unit.
There are three ports on the valve block as listed:
• Port 1: Low Pressure output approximately 40-50 PSI normally is blanked off but may be used to supply another filter housing
• Port 2: High pressure input up to 3000 PSI
• Port 3: Return to hydraulic reservoir. This port is fitted with adaptors to suit particular applications e.g. JIC, BSP and it is important that the return hose is of at least 3/8 bore for hydraulic systems.
Hydraulic Fluid Facts:
• More than 70% of hydraulic failures are caused by contaminants in the oil.
• Heavily contaminated oil can reduce power by as much as 15-20%, slowing machine response and taking longer to perform an operation.
• By following a few basic rules, the life of piston rods, seals, valves, and pumps can be more than doubled.
• By maintaining the hydraulic fluid in 'as-new' condition, the life of the same components can be increased ten-fold.
Particles Breed Particles: An abrasive particle passing through the system scrapes off further particles. Larger ones join the original to create a mass of wear catalysts, smaller ones become silt which builds up on metal surfaces to clog oil flow and cause sticking valve components. In line filters do not remove silt, (particles below 15 micron) and do not remove water.
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)
NAS GRADE is a widely adopted standard to measure the contamination degree of hydraulic oil.
