• Adapter with trapezoidal thread
• Fine filter in clear filter bowl

FN09S
for D06F pressure reducing valves
Product specification sheet
Application
Habedo
retrofitting to existing D06F pressure reducing valves. The
converted pressure reducing valve then fulfills the same functions
as a Honeywell filter combination. The fine filter prevents the
ingress of foreign bodies, for example rust particles, strands of
hemp and grains of sand. The appliances correspond to current
DIN/DVGW specifications.
Special Features
• DIN/DVGW approved in conjunction with the pressure redu-
• Easily fitted to existing pressure reducing valves
• Filtered water supplied even during reverse rinsing
• Patented reverse rinsing system - fast and thorough cleaning
• Memory ring indicates when next manual reverse rinsing is
• Automatic reverse rinsing actuator with bayonet connector
• Large filter surface
• Shock resistant clear synthetic material filter bowl enables
• Filter and complete filter bowl are replaceable
• 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 comprises an upper part and a lower combination
section. When in the „filtering“ position, the small upper filter is
closed so that the water can only pass through the main filter
from outside to inside. When the ball valve is opened for reverse
rinsing, the filter 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 sieve, the
rotating impeller and the main filter from inside to outside. By this
means, the filter is fully cleaned over its whole surface area at the
full inlet pressure. The filter automatically switches over to the
operating position when the ball valve is closed again.

Installation Example
FN09S Habedo®-retrofit 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 Degree of contamination can be seen with clear filter bowl
o Simplifies maintenance and inspection
• Remove filter bowl and filter from pressure reducing valve and
replace with FN09
• The installation location should be protected against frost

Typical Applications
Retrofit filters of this type are suitable for subsequent fitting to
existing D06F pressure reducing valves. They are suitable for
supplies to all types of household installations. They can also be
used for commercial and industrial applications within the limits
of their specifications.
Retrofit 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
