Return Line Filter RF014-RF130 Technical Data
Technical Data
STAUFF RF 014-130 return line filters
are designed as tank top filters. They are
mounted directly on the tank top and
when 100% of the system’s oil is filtered,
they provide the optimum removal of
contaminant from the system. This
provides the pump with clean oil thus
reducing contaminant generated
wear. The filter bowl or funnel is designed
to return the oil beneath the surface
thus preventing the entrainment of air
by the returning oil.

Options RF 014-130
1. Visual clogging indicator HI-M The gauge visually displays the degree of contamination of the element. The colored segments allow quick visual checking.
green 0...2.5 bar (0…36.25 PSI) Element has service life left yellow 2.5...3.0 bar (36,25 ...43.5 PSI) Element is contaminated and should be changed red >3.0 bar (>43.5 PSI) By-pass valve open, unfiltered oil passing to tank
Visual clogging indicator
2. Electrical clogging switch HI-G The switch is used where an electrical signal is needed to indicate when the element needs changing. The switch can turn on a light, or shut the machine down, or any further function controlled by an electric signal. The switching pressure is 2,5 bar (36,25 PSI) and this allows the element to be changed before the by-pass setting of 3 bar (43,5 PSI) is reached.
Maximum Voltage Switch Type 42 V HI-G 42 110 V HI-G 110 220 V HI-G 220
Electrical Clogging Switch
3. Leakage oil connection Seal or case drain lines can be connected to the filter through either of the clogging indicator ports providing that the leakage oil can accept a pressure of 3 bar (43.5 PSI). It ensures that no un-filtered oil can return to the reservoir. It may save the cost of a manifold.
Leakage oil connection
4. Filter bowl with threaded connection
Under some circumstances such as a tall reservoir or one with oil levels which vary greatly during operation, it is necessary to extend the filter bowl so that the returning oil returns beneath the surface and does not entrain air in the process. The optional bowl with a female thread allows an extension to be fitted quite simply.
Threaded outlet
5. Filter bowl with threaded connection and diffuser
Diffusers mounted to the filter bowl minimize foaming and reduce noise of high return line flows. For further details on STAUFF diffusers please refer to the “Hydraulic Accessories” section of this catalog.
