Sand
Media Filter For the Most Challenging Source
Water Conditions
Proper filtration and clean water are essential
to the efficient operation of today's irrigation systems.
Trash, algae, sand, silt and other solid contaminants in source
waters will lead to plugged nozzles, silt deposition, inoperative
valves, and a significant reduction in overall efficiency.
Rain Bird filtration technology can resolve these problems
in your system. Rain Bird's Sand Media Filters provide reliability,
efficiency and long-term economy. Made in the USA, these filters are designed and manufactured to exacting
standards, giving you many years of top performance.
Features and Benefits:
Filter Tanks
Rain Bird filter tanks are designed to provide safety features
not found in competitve products. All closures have safety
lids that will no pop off if overpressurized. Rain Bird's
tank construction is also heavier than average, giving you
extra protection against bursting from accidental overpressurization.
Automatic Valves
Rain Bird cast valves feature a fusion epoxy lining designed
for years of trouble-free service. The valve shaft and seal
retainers are noncorrosive stainless steel with durable, molded
polyurethane seals. Also, the valves are made with Rain Bird's
exclusive replaceable brass shaft guides and external grease
fittings for easy on-site maintenance.
Stainless Steel Underdrain
Rain Bird's underdrain system features a lateral design of
high strength, stainless steel wedgewire. It produces a pressure
drop of only 4 PSI and will withstand collapse pressure in
excess of 600 PSI. Unlike other manufacturers, Rain Bird does
not use plastic underdrain parts or threaded fastener underdrain
assembly because of limited durability.
Automatic Control
Optional automatic control makes Rain Bird your most cost-effective
choice for your next filtration system. Rain Bird automation
packages allow fully unattended operation. All Rain Bird controllers
monitor system operation on both pressure differential and
elapsed time. Units are available in A/C, D/C or solar power
for remote application.
Fusion Bonded Epoxy Interiors Available
All Rain Bird Sand Media Filter systems are available with
optional fusion-epoxy lining. This premium environmental coating
system provides excellent protection against aggressive electrolysis
and corrosion. The Rain Bird fusion powder coat system is
applied to all interior surfaces of filters and manifolds
after sandblasting to white metal. The Rain Bird fusion bonded
epoxy system is a true environmental coating providing years
of protection for salts, chemicals and other matherials found
in aggressive water.
Filtration Process
Uniform 14" media bed depth for optimum particle
entrapment
Filtration achieved through flow from inlet (top) manifold
to outlet (bottom) manifold
2-stage inlet diffuser
High strength, hydraulically balanced Type 304 stainless
steel underdrains for thorough backwashing
Low pressure drop and even flow dispersion
Backwashing Process
Rain Bird underdrains require less water for backwashing
and require backwashing less frequently
Clears one tank at a time, so you can continue to irrigate
during the backwash cycle
The system backwashes with clean-filtered water
Single valve operation, either manually, semiautomatically
or automatically, assures proper backwashing efficiency
and sequence
Evenness of media bed fluidization ensures total cleaning
of the system, while producing a flat, uniform media bed
after flushing
