F76S-ZFA
Reverse rinsing fine filter with flanges
Product specification sheet
Application
F76S-ZFA 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-ZFA flanged filters have the same highly efficient reverse rinsing filtering system as the range of household
fine filters. The F76S-ZFA 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. With metal or plastics pipework, DIN
1988, Part 2 specifies that a filter should be fitted in the drinking
water supply immediately after the water meter.
Special Features
• DIN/DVGW-approved
• Filtered water supplied even during reverse rinsing
• Filter insert fully interchangeable
• Patented reverse rinsing system - fast and thorough cleaning
of the filter with small amount of water
• Fully automatic reverse rinsing with retrofittable Z11AS 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
• Large filter surface
• Tested to European drinking water supply standards
• 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-ZFA 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.
