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 either
on elapsed time since the last backwashing or 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 400 PSI 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.
