F76S-11/2AA Honeywell filter with backwashing

The water filter with backwashing ensures a continuous supply of filtered water even during the cleaning process of the filter mesh. The fine mesh filter captures foreign bodies such as rust particles, hemp fibers, sand grains, etc.

All components of the device meet the requirements of current DIN/DVGW standards. Used in both domestic and industrial installations.

Connection diameter: 11/2"

Filter features:

• Filtered water is supplied even during backwashing
• The patented backwashing system is quick and allows the filter to be cleaned with a small amount of water
• A special adjustment ring indicates when the next backwashing should be performed
• The filter can work with an automatic backwashing device
• Large filtration surface
• The transparent filter housing made of impact-resistant synthetic material allows for easy monitoring of the contamination level of the cartridge
• Replaceable filter cartridge and housing
• Very simple operation
• Manufactured in accordance with KTW recommendations for drinking water

Operating principle:

• The filter cartridge consists of an upper and lower part.
• In the "filtration" position of the knob - the upper filter cartridge is closed so that water only passes through the lower, main cartridge from the outside to the inside.
• When the ball valve is opened for backwashing, the main filter cartridge is pushed down until the water supply from the outside is stopped. At the same time, the water flow to the upper part of the filter is opened.
• The water used for cleaning passes through the screen, rotor, and main filter cartridge from the inside to the outside. This means that the cartridge is thoroughly cleaned over its entire surface at full inlet pressure.
• The filter automatically returns to the operating position after the ball valve is closed.
• The internal rotor flushes contaminants adhering to the mesh through the discharge openings.

Construction The filter consists of:

• Housing with a pressure gauge
• Threaded connections
• Fine mesh filter cartridge
• Transparent filter housing
• Ball valve with drain cover
• Box wrench for the filter housing

Materials:

• Housing made of dezincification-resistant brass
• Threaded connections made of brass
• Filter cartridge made of stainless steel
• Filter housing made of red brass or impact-resistant, transparent synthetic material
• Nitrile rubber (NBR) seals

Installation guidelines:

• Horizontal installation with the filter housing facing down - this position ensures optimal efficiency
• Installation of shut-off valves on both sides of the water meter
• Ensuring access to the device so that the pressure gauge is clearly visible - with the transparent filter housing, it is easy to determine the contamination level of the filter mesh, facilitating maintenance and monitoring
• Installation directly behind the water meter in accordance with DIN 1988, Part 2
