Netafim SandStorm 4 Tank Manifold Fully Automatic Gravel Media Filter System with Media – AC Controlled

The Netafim SandStorm 4 Tank Manifold Fully Automatic Gravel Media Filter System with Media – AC Controlled is a high-capacity metal media filtration system engineered for large-scale irrigation applications requiring reliable primary filtration from poor-quality surface water. Constructed from carbon steel ST-37.2, the SandStorm system combines rugged durability with efficient depth filtration to protect irrigation infrastructure and maintain consistent system performance.

The four-tank manifold (quad system) configuration delivers increased filtration area and higher flow capacity, allowing uninterrupted irrigation while individual tanks perform automatic back-flush cycles. A special two-layer UV and corrosion-resistant coating ensures long service life in harsh outdoor environments. Designed with modular expansion in mind, the SandStorm system can be scaled as irrigation demands grow, while large access ports allow easy gravel media replacement and routine maintenance. Supplied complete with gravel media, the system is ready for installation and operation.

Media filters are highly recommended when irrigating with poor quality water or in the following conditions:

• As the primary filtration for surface water in single/multi-season driplines
• When water contains Iron and/or Manganese
• For SDI applications wish harsh water sources
