Drinking water filter DN20 RATIO Start DFR with pressure reducer, with backwash 5315.20.100

Drinking water filter with pressure reducer and backwash

This RATIO Start DFR drinking water filter is a comprehensive solution for water purification, designed for both home use and more demanding installations. Equipped with a pressure reducer, it ensures stable and safe water pressure throughout the system. The backwash mechanism simplifies filter cleaning, extending its lifespan and maintaining high efficiency.

Construction and application

The RATIO Start DFR filter consists of three key elements: a Ratio mechanical filter, a Ratio Bypass bypass valve, and a mounting flange. This construction allows for easy installation on the supply pipeline (available sizes DN15, DN20, DN25) and flexible adaptation to different needs. The bypass valve allows bypassing the filter if necessary, e.g. during servicing or maintenance. This is particularly useful when connecting water softeners or other devices requiring a constant flow.

Advantages and benefits

• Pressure reduction: The built-in pressure reducer (compliant with PN EN 1567 standard) maintains a constant output pressure in the range of 1.5 – 6 bar, protecting the installation from damage caused by excessive pressure.
• Backwash: The manual backwash mechanism allows for effective removal of contaminants accumulated in the filter, which extends its lifespan and ensures continuous high quality of the filtered water.
• Versatility: The filter can be used as a standalone device or in combination with other elements of the water treatment system.
• Easy installation: The mounting flange facilitates installation of the filter on the supply pipeline.
• Compliance with standards: The Ratio filter meets the requirements of PN EN 13443 standard for mechanical filters for drinking water.
• Bypass valve: Allows bypassing the filter without having to shut off the water supply – an ideal solution during servicing or filter cartridge replacement.

The RATIO Start DFR filter is a reliable solution for anyone who cares about the quality of drinking water and wants to protect their installation from the effects of high pressure and sediment. Its solid construction and ease of use make it an ideal choice for both professional installers and home users.
