Remove Dirt Particles

The new AFRISO WAF 02 R back washable water filter with pressure reducer from Afriso-Euro-Index GmbH (Germany) has been designed to protect drinking water installations against corrosion as per DIN 1988 and prevents the ingress of pollutants (such as rust, sand, hemp).

The water filter protects, for example, flow heaters, valves or machines against malfunctions caused by dirt. WAF 02 R is not DVGW-tested, but the materials are physiologically unobjectionable and comply with the German Drinking Water Act. The fitting consists of a brass filter head with integrated pressure reducer and pressure gauge as well as a transparent filter cup with a 7" filter insert. A rotatable brass connection piece enables installation in horizontal or vertical pipes, even if the pipe is very close to a wall. The pressure reducer is adjustable from 1.5 to 6 bar to ensure an even outlet pressure/system pressure. The pressure gauge (0-10 bar, optionally available with pressure gauge 0-16 bar) indicates the outlet pressure and features a rotatable window that allows the user to mark the date of the last backwashing.

The degree of pollution can also be easily detected through the transparent filter cup. The water filter is backwashed via a drain valve. The direction of flow through the filter insert is reversed and the dirt particles are flushed out. The filter should be backwashed every 2 months. The WAF 02 R water filter is optionally available with a backflow preventer, which keeps water from flowing back into the public water supply, and with a replaceable filter insert. WAF 02 R is suitable for water temperatures of up to 30 °C, inlet pressures of up to 16 bar and outlet pressures of up to 6 bar. Rotatable G3/4 or G1 connections allow for fast and easy retrofitting or replacement of old or defective water filters.
