Yardney pioneered the use of sand media filtration for irrigation back in 1965. With over 100,000 systems in operation today, Yardney has defined the technology and art of irrigation filtration. The Yardney Sand Media Filter being produced today utilizes the same basic filtration principles as were pioneered in 1965. Through advanced technology and continued product improvements, all Yardney Filters are state-of-the-art in efficiency, performance, reliability, and long-term value. All Yardney Sand Media Filters are made in the U.S.A.

Proper filtration and clean water are essential to the efficient operation of today's irrigation systems. Trash, algae, sand, silt and other solid contaminants present in irrigation source waters will lead to plugged drip emitters, sprinklers, inoperative valves and an overall significant reduction in system efficiency. Yardney Filters are designed and manufactured to the most exacting standards. State-of-art welding and fabrication techniques assure that Yardney product designs are manufactured to provide a long useful system life.

Filtration Process
1. Filtration achieved through flow from inlet (top) manifold to outlet (bottom) manifold
2. High strength, hydraulically balanced type 304 stainless steel underdrains for thorough backwashing.
3. 2-stage inlet diffuser to assure non-turbulent laminar flow.
4. Uniform 14" media bed depth for optimum particle entrapment.
5. Low pressure drop and even flow dispersion.

Backwashing Process
1. Yardney underdrains require less water for backwashing and require backwashing less frequently than others.
2. Backwashing one tank at a time, while continuing to irrigate during the backwash cycle.
3. System backwashes with clean filtered water produced by the system.
4. Single valve operation, either manually, semi automatically, or automatically assures proper backwashing efficiency and sequence.
5. Evenness of media bed fluidization assures total cleaning of the system, while assuring a flat, uniform media bed after flushing.
