Netafim SandStorm 3 Tank Manifold Fully Automatic Gravel Media Filter System with Media – AC Controlled

The Netafim SandStorm 3 Tank Manifold Fully Automatic Gravel Media Filter System with Media – AC Controlled is a heavy-duty, double-chamber metal media filtration system engineered for high-flow irrigation applications using poor-quality surface water. Manufactured from carbon steel ST-37.2, the SandStorm system delivers reliable depth filtration, robust structural integrity, and long-term performance in demanding agricultural environments.

The three-tank manifold configuration provides increased filtration capacity and enhanced operational continuity, allowing the system to maintain irrigation flow while individual tanks undergo automatic back-flush cycles. A special two-layer UV and corrosion-resistant coating ensures long service life even in harsh outdoor conditions. The modular manifold design enables future expansion, while large access ports simplify gravel media replacement and routine maintenance. The system is supplied complete with gravel media, making it 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
