Netafim SandStorm 2 Tank Manifold Fully Automatic Gravel Media Filter System with Media – DC Controlled

The Netafim SandStorm 2 Tank Manifold Fully Automatic Gravel Media Filter System with Media – DC Controlled is a double-chamber metal media filtration system designed for primary filtration in irrigation systems using poor-quality surface water. Manufactured from high-quality carbon steel ST-37.2, the SandStorm system delivers reliable depth filtration, robust construction, and efficient automatic back-flushing for demanding multi-season irrigation applications.

The two-tank manifold configuration allows continuous filtration during back-flush cycles, maintaining uninterrupted irrigation flow. Featuring industry-leading UV and corrosion protection through a special two-layer coating, the SandStorm system is engineered for long-term operation in harsh outdoor environments. Its modular design supports future system expansion, while large access ports simplify media replacement and routine maintenance. The system is supplied with gravel media, providing a complete, ready-to-install filtration solution.

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
