Features

Performance

The principle of the RMF Systems filters is based on the unique original filter elements. With a choice of filter fineness down to 0,5 micron and Filter efficiency up to β4=10.000, they have the capacity to remove even the smallest of dirt particles from the oil. RMF System’s Off-line kidney loop oil filtration system offers a wide range of elements in micron sizes, filter media, and fluid compatibility. Combi-elements (water and solid particle retention) complement the unique range.

Water Absorbing

RMF Water absorbing filters are off-line filters that use a special water-absorbing spin-on as a pre-filter. The fluid is pumped through the pre-filter which removes most water and larger solid contamination, in the second stage the fluid passes through the RMF cellulose micro filter where final water removal takes place as well as solid particle removal.

Applications

The RMF off-line units attack contamination of your system at the source. In addition to solid particles, these filters are also capable of removing water from the oil. The use of RMF filters means less defects, less maintenance and less wear and tear of the hydraulic components. The RMF Off-Line units can be fitted to every imaginable industrial application where hydraulic or lubrication systems are present.

In recent years RMF Systems have developed a great deal of experience in cleaning and keeping clean hydraulic and lubrication systems in the:

Steel industry
Plastic moulding industry
Maritime industry
Petro-chemical industry
Paper industry

Benefits

Reduced cost of ownership
Extremely clean oil due to high filtration efficiency
Prevention of channel forming by radial filtration direction
Large dirt holding capacity
Large water holding capacity
Compact and easy maintenance design
Longer usage life for oil and components

Did You Know...

Contamination is the greatest single cause of lubrication malfunction and subsequent excessive wear of parts?

Less than 0.5% of a plant’s maintenance budget is spent purchasing lubricants, but the downstream effects of poor lubrication can impact as much as 30% of a plant’s total maintenance cost each year.
