F76CS/FN76CS
Reverse rinsing filter
with clear filter bowl
Product specification sheet
Application
F76CS/FN76CS reverse rinsing filters ensure a continuous
supply of filtered water. The fine filter prevents the ingress of
foreign bodies, for example rust particles, strands of hemp and
grains of sand. The appliances correspond to the requirements of
current DIN/DVGW specifications..
F76CS/FN76CS fine filters are especially suitable for retrofitting
to, or upgrading of existing water systems.The rotatable
connector piece enables the unit to be fitted where space is very
restricted in either horizontal or vertical pipework.
Special Features
• DVGW-approval requested
• Double Spin Technology
o Cartridge with external rotor enabling simultaneous
cleaning in lower and upper filter areas
o Visual function check possible
• Filtered water supplied even during reverse rinsing
• Patented reverse rinsing system - fast and thorough cleaning
of the filter with small amount of water
• Memory ring indicates when next manual reverse rinsing is
due
• Automatic reverse rinsing actuator with bayonet connector
can be retrofitted
• Large filter surface
• Shock resistant clear synthetic material filter bowl enables
easy checking of filter contamination
• Filter and complete filter bowl are replaceable
• With a retrofit D06FB pressure reducing valve, can be
converted to a filter combination
• Standardised discharge connection
• Meets KTW recommendations for potable water
Range of Application
Medium Water
The filter is constructed for drinking water installations. In case of
a process water application the filter has to be proven individually.

Method of Operation
The filter insert is divided into two parts. In the „filtering“ position,
only the lower, larger section is rinsed through by water jets from
outside to inside. The small upper section does not come in
contact with unfiltered water. When the ball valve is opened for
reverse rinsing, then the whole filter insert is pushed downwards
until the water supply to the outer side of the main filter is
stopped. Simultaneously, the water flow is opened to the upper
part of the filter. The water needed for cleaning the filter passes
through the upper filter section, then the rotating impeller and the
main filter from inside to outside, i.e. the filter is reverse rinsed
with filtered water. In that way the upper filter is also cleaned by
jets from the impeller. The filter automatically switches back to
the operating position when the ball valve is closed again.
Filters with Double Spin Technology have turbine blades which
circulate the water and thereby set the rotor on the upper filter
into a rotational motion. The internal impeller rinses off particles
that have adhered to the upper filter at the intersecting points
with the rotor.
