F76S-F
Reverse rinsing fine filter with flanges
Product specification sheet
Application
F76S-F flanged reverse rinsing filters are for installations with high
water demand. They can be used in large residential buildings, for
central water supply and in commercial or industrial applications.
F76S-F flanged filters have the same highly efficient reverse
rinsing filtering system as the range of household fine filters. The
F76S-F can be retrofitted with the Z11AS fully automatic reverse
rinsing actuator and the DDS76 differential pressure switch. The
use of a filter in a system prevents the ingress of foreign bodies,
for example rust particles, strands of hemp and grains of sand.
Special Features
• DIN/DVGW approved
• Filtered water supplied even during reverse rinsing
• Filter insert fully replaceable
• Patented reverse rinsing system - fast and thorough cleaning
of the filter with small amount of water
• Fully automatic reverse rinsing with retrofittable automatic
reverse rinsing actuator
• Differential pressure switch can be retrofitted
• Reverse rinsing strainer mesh is covered during normal
operation
• Red bronze construction gives high level of corrosion protection
• Forced flow provides optimal water exchange in the filter bowl
• Meets KTW recommendations for potable water
• Standardised discharge connection
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-F Reverse rinsing fine filter with flanges
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.

Typical Applications
Fine filters of this type are suitable for large residential buildings,
commercial and industrial applications and for central water
supply systems within the limits of their specifications.
Fine filters of this type are installed:
• Where there is existing metal or plastics pipework
• In transfer points for central water supply systems when drainage is available
• If the downstream system includes appliances which must be
protected against dirt
