Hazards Posed by Stored Residual Energy
WARNING
Hydraulic systems are under pressure
Danger of bodily injury
►The hydraulic system must be depressurized
before performing any work on the hydraulic
system.
Note that the unit may pose a hazard as the result of residual stored mechanical
and electrical energy. Take the proper precautions when instructing personnel on
the use of the unit. Detailed information is provided in the respective sections of this
manual.

Technical Description
The MultiRheo Filter MRF is a stationary filtration unit used for the full-flow and
bypass filtration of low-viscosity fluids for separating out particles from 100 microns
to 1 micron (absolute) in size.
The MultiRheo Filter is a filter series for the use of Flexmicron filter elements.
Suitable fluids
NOTICE
Impermissible operating media
The MRF will be destroyed
►Only use the MRF in connection with:
- lubrication and mineral oils or media based on mineral oil
- cooling lubricants
Filter Design
The total pressure of the filters at a specific flow rate is comprised of the housing
pand the element p. 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.

Pressure loss curve, housing
bar
Flow rate in l/min
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.
