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.
Heated Off-Line Filters
The ‘Heated unit’ is a unique progression of the Off-line filter series. The filtration of high viscosity oils, in both hydraulic and lubrication systems, is an almost impossible task for fine filters as the thickness of these oils ‘block’ almost all normal filters. The RMF Heated unit warms the oil in a specific manner, allowing the viscosity to be reduced to a level which will permit fine filtration without the oil being exposed to too high temperatures that could cause overheating and burning of the oil, rendering it useless.
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
Efficiency
The hydraulic market accepts that 80% of mechanical failures are caused by contamination in the system. The RMF Off-Line Units attack contamination of your systems at 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.
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.
It cost ten times as much to remove contamination from equipment than it does to exclude it?
