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 1 /

" 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.

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.

F76S Reverse rinsing fine filter
Installation Example
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
