Automatic Backwashing Screen Filter The Ultimate High-Rate Screen Filtration System
Rain Bird’s Automatic Backwashing Screen Filter provides the ultimate in high-rate screen filter performance. Powered by source line water pressure, the filter’s patented backwashing valve system produces a reverse flow to flush the system of entrapped contaminants.
During the brief backwashing cycle, a portion of the clean water produced by the system is diverted to the filter unit undergoing backwashing. This reverse flow of filtered water frees contaminants from the filter screens. Each filter canister is sequentially backwashed until the entire system is cleaned.
Features and Benefits:
Automatic Monitoring
This filtration system is automatically monitored both on elapsed time since the last backwashing and pressure differential. This dual monitoring offers the user the flexibility to assure that filter operation is maintained with high efficiency, low pressure drop and consistent high quality produced water. Rain Bird automatic controls are available for A/C power, D/C power and solar power applications.
Long-Lasting Construction
The Automatic Backwashing Screen Filter is built for years of durable, trouble-free service. The filter canisters are constructed of carbon steel, which is fusion epoxy lined as a standard feature. The carbon steel manifolds and the cast iron backwash valve are also fusion epoxy lined. The permanent stainless steel filter screens require no maintenance. In addition to the automatic backwashing cycle, the filter canisters and screens have no internal moving parts to wear out, break down or replace. And, the high strength stainless steel canisters are constructed with 2760kPa burst strength. A patented backwash valve features stainless steel valve trim and a field-replaceable polyurethane valve sealing element. The backwash valves also feature external lubrication fittings for easy field service. In fact, the unit is totally field rebuildable.
