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

The Netafim SandStorm 4 Tank Manifold Fully Automatic Gravel Media Filter System with Media – DC Controlled is a high-capacity metal media filtration solution designed for primary filtration in large-scale irrigation systems using poor-quality surface water. Manufactured from robust carbon steel ST-37.2, the SandStorm system delivers reliable depth filtration, long service life, and consistent performance in demanding agricultural environments.

The four-tank manifold (quad system) configuration provides increased filtration area and higher flow capacity, allowing continuous irrigation while individual tanks perform automatic back-flush cycles. A special two-layer UV and corrosion-resistant coating ensures long-term durability in harsh outdoor conditions. The modular manifold design allows the system to be expanded as irrigation demands grow, while large access ports simplify 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
