Automatic Backwashing Screen Filter
Automatic Backwashing Screen Filter
High Performance with Fewer
Moving Parts
Rain Bird®’s Automatic Backwashing Screen Filter
provides worry free high‑flow rate 250 micron
(standard) filtered water quality. 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
wedge‑wire filter screens. Each filter canister is
sequentially backwashed until the entire system is
cleaned, allowing irrigation continue through the
backwash cycle. Models are available as a
filter unit only, or as a filter assembly including
bypass plumbing and valves for fast and easy
installation on site.
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 water production. 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 stainless
steel filter screens are of a low maintenance
design and require only periodic maintenance
to maintain the filter element. 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
a 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.

Filter flow is based on 250 micron filtration and above of clear irrigation water. Appropriate flow de-rating is required for excessive debris loads (silt, organics, algae, etc.), reclaim water and finer
screens. Contact Rain Bird for filter selection assistance for these applications.
