Dangers by pressure in the hydraulic system
WARNING
Hydraulic systems are pressurized
Danger of bodily injury
►The hydraulic system must be depressurized
before performing any work on the hydraulic
system
MRF modification
Do not make any modifications (design modifications, extensions) to the MRF
without the prior consent of the manufacturer.
Immediately replace any unit components which are not in perfect condition.
Use only original spare parts (OEM).
Unpacking MRF
When receiving and unpacking the unit, check it for damage in transit.
The connectors/ports are closed off so that no contamination can enter the unit
while it is in transit.
Dispose of the packaging material as appropriate for your area.
Storing the MRF
Store the filter in a clean, dry place.
Drain the filter housing completely before putting it into storage.
Check the external corrosion protection (paint coat) for damage, apply a new coat or
touch up the existing one as needed.
Wet the cleaned filter interior and all sealing surfaces such as the flange with a
suitable corrosion inhibitor, e.g. ANTICORIT 3 by Fuchs-DEA.
Storage temperature: 5 … 30°C
Humidity: up to 50% relative humidity

Technical specifications
The MultiRheo Filter MRF is a stationary filtration unit used for full-flow and bypass
filtration of low-viscosity fluids for the separation of particles of 100 ... 1 µm
(absolute).
The MultiRheo Filter is part of a filter series for the use of Flexmicron filter elements.
Restrictions pertaining to use
NOTICE
Impermissible operating media
The filter will be damaged.
►The unit is only to be used with mineral oils or mineral oil-based raffinates or
for cooling lubricants.

MRF7 Calculating the pressure differential of the filter housing / filter element
Calculating the pressure differential of the filter housing / filter
element
The total pressure of the filters at a specific flow rate is comprised of the housing
and the filter element . The pressure loss of the housing can be determined
using the following pressure loss curve. The pressure loss of the filter elements is
computed on the basis of the R factors.
pp
Housing : Pressure loss curve, housing
p
The upper housing curve holds for mineral oil with a density of 0.86 kg/dm³ and a
kinematics viscosity of 30 mm²/s. The lower housing curve holds for water at 20°C.
For turbulent flow, the differential pressure will change proportionally to the density;
for laminar flow, it will change proportionally to the density and viscosity. The flow
velocity should not exceed 3 m/s at the filter inlet for oil and 4 m/s for water.
