Backwash filter for up to 70°C, with fittings, 3/4 inch, 100 micron mesh F76S-3/4AAM

Effective protection of the installation and clean water with the Honeywell F76S filter

The F76S backwashing water filter is a reliable solution for ensuring clean water in domestic and commercial installations. Designed for use with potable water, it effectively removes mechanical impurities such as rust, sand, and hemp fibers, protecting devices from damage and extending their lifespan. Thanks to the backwashing function, the filter maintains high efficiency without the need to interrupt the water supply.

Design and operating principle

The F76S features a solid construction based on dezincification-resistant brass (DZR), guaranteeing durability and corrosion resistance. The stainless steel filter cartridge with a 100-micron mesh effectively traps impurities. The backwashing system, utilizing double spiral technology (in selected models), allows for quick and effective filter cleaning with minimal water consumption. The transparent housing allows for visual control of the filter cartridge's contamination level, and the pressure gauge allows you to monitor the pressure drop, indicating the need for flushing.

Application and benefits

This filter is used wherever protection of the water installation from impurities is required – both in new and modernized systems. It is ideal for protecting heating devices, heat pumps, washing machines, and dishwashers. Horizontal mounting provides easy access to the cartridge during maintenance. Using the F76S filter translates to:

• Long-term installation protection: Removing impurities prevents corrosion and scale build-up.
• Constant supply of clean water: The filter provides uninterrupted access to filtered water even during the backwashing process.
• Efficient device operation: Protection against impurities increases efficiency and extends the life of connected devices.
• Low operating costs: The ability to backwash reduces the need for frequent filter cartridge replacement.
• Simple installation and maintenance: The filter is easy to install and operate, and the transparent housing makes it easy to check the cartridge condition.

Technical parameters

The F76S-3/4AA filter is characterized by a 3/4 inch (20 mm) threaded connection and a maximum working pressure of 25 bar. The nominal flow rate is 5.5 m³/h with a pressure drop of 0.5 bar. The gasket material is NBR (nitrile butadiene rubber), ensuring a tight seal. The device has a pressure indicator and is equipped with a filter cartridge with a mesh size of 100 µm. The filter's installation length is 178 mm and the housing height is 350 mm. The filter is designed to operate at a temperature from 2°C to 70°C. The Kvs value is 7.2, which means a high filter flow rate.

Additionally, the product is covered by a 5-year warranty from the date of manufacture, which confirms its high quality and reliability.
