Backwash water filters WAF 03 and WAF 04
The new AFRISO backwash water filters WAF 03 and WAF 04 keep dirt particles such as rust, sand or hemp residue from getting into the domestic installation, thus ensuring cleaner drinking water. Uninterrupted supply of filtered water is even assured while the filter is being backwashed.

The filter combination consists of a plastic housing with a pressure gauge and a transparent filter bowl with an integrated fine filter made of stainless steel. The WAF 04 water filter features an integrated pressure reducer - the prepressure is adjusted by means of a spring-loaded hood with an adjustment handle and an adjustment indicator.

A prepressure compensation system ensures that changing prepressure does not affect the downstream pressure; constant system pressure is good for the installation and supports economical water consumption. The fine filter removes all dirt particles from the water and it can be backwashed - when the ball valve is opened, all collected dirt particles are flushed out of the filter. When the valve is closed again, the filter automatically resumes normal operation. The degree of pollution of the filter can be easily seen from the outside; the rotatable window of the pressure gauge allows you to mark the date of the next backwashing cycle.

The DVGW-tested water filters WAF 03 and WAF 04 are suitable for operating temperatures of up to 30 C, a prepressure of up to 16 bar, a downstream pressure of 1.5 to 6 bar and they are available with G 3/4, G 1 or G 1 1/4 connections. The water filters are suitable for domestic installations and, under consideration of the specifications, for industrial and commercial purposes.

The filters can easily and quickly replace obsolete or defective water filters or be retrofitted in existing domestic water installations.
