Maxi-Flush Screen Filters
Automatic Backwash System

Yardney Maxi-Flush Screen filters provide the ultimate in high rate screen filter performance. Built for durable trouble-free service, the filter and cartridge have no internal moving parts to wear out, break down or replace. The field changeable stainless steel filter cartridge requires no maintenance and is constructed with a burst strength in excess of 400 psi.

The patented Yardney 3-way backwash valve controls the highly effective reverse flow backwashing. During the brief backwashing cycle a portion of the clean water produced by the system is diverted to the filter housing undergoing backwashing. This flow of clean water frees contaminants from the cartridge while discharging these contaminants from the system and restoring the filter back to a clean filter condition. Each filter housing is sequentially backwashed until the entire system is cleaned.
