Technical Description
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 MultiRheo Filter will be damaged.
►The unit is only to be used with mineral oils or mineral oil-based raffinates or
for cooling lubricants.

MRFD2N 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.

Differential pressure (bar)
Flow rate (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.
