F76S

Reverse rinsing fine filter

Product specification sheet

Application

F76S 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..

Special Features

• DIN/DVGW approved

• Double Spin Technology for connection sizes

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

• Also available without connections

• 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.

F76S Reverse rinsing fine filter

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.

Installation Example

F76S Reverse rinsing fine filter

Installation Guidelines

• Install in horizontal pipework with filter bowl downwards

o This position ensures optimum filter efficiency

• Install shutoff valves

• Ensure good access

o Pressure gauge can be read off easily
o Degree of contamination can be easily seen with clear filter

bowl

o Simplifies maintenance and inspection

• The installation location should be protected against frost

• Fit immediately after water meter

o Corresponds to DIN 1988, Part 2

Typical Applications

Fine filters of this type are suitable for supplies to buildings of all
types. They can also be used for commercial and industrial appli­cations within the limits of their specifications.

Fine filters of this type are installed:

• Where there is existing metal or plastics pipework

• If the downstream system includes appliances which must be
protected against dirt
