Performance description
4.1
The off-line filter system 30 (50, 80) NFF2 is a mobile filter system for the filtration
of hydraulic fluids and lubricants with a viscosity of 10 - 200 mm
2
/s on the bypass.
Separate installation in the bypass or cooling circuit for the fine filtration and
unloading of the main flow filter is just as feasible as the filtration of fresh oil and
the cleaning (flushing) of polluted systems for protecting components and system
against wear and tear.
The flow amounts to 30 l/min (30 NFF2) or 50 l/min (50 NFF2) or 80 l/min (80 NFF2).
The operating temperature ranges from –10 °C to 60 °C.
Device description
4.2
The 30 (50, 80) NFF2 off-line filter system consists of a one-axis supporting frame
to which a filter pump unit has been attached. The 80 NFF2 0270 is an exception;
it has been attached to a two-axis frame. The filter pump unit consists of an elec-
trically operated filter pump with exchangeable suction filter and a main filter with
electronic maintenance indicator. If the pressure differential exceeds the value of
2.5 bar, the pressure resistance in the suction line is too high. A vacuum meter
monitors the pump suction pressure and displays the pressure. The on/off switch
is located at a control box. The suction hose is connected at the suction-side port
of the protective pump filter and the pressure hose at the main filter output. At
their ends, the hoses are in each case equipped with a lance. When they are not
used or during transport, they can be fixed in a receiving tube.
