SM-Series4 Sand Media Filters – Built for Agriculture, Engineered to Last

When it comes to agricultural irrigation, performance, reliability, and longevity matter. The SM-Series4 Sand Media Filters are purpose-built to meet the rigorous demands of growers, irrigation engineers, and farm operations that rely on dependable filtration to protect their water systems. Designed for efficiency, engineered for strength, and built to last, the SM-Series4 sets the new benchmark in agricultural sand media filtration.

Why Reliable Filtration Matters in Agriculture

In modern agriculture, clean water is critical. Irrigation systems are the lifeblood of crop productivity, and any contamination, sediment, organic matter, or debris can clog emitters, reduce flow, and compromise yield. A robust sand media filtration system acts as the first line of defense, ensuring consistent performance in drip, sprinkler, and micro-irrigation systems.

The SM-Series4 isn’t just another filter; it’s a system designed for maximum uptime, easy maintenance, and superior protection of valuable irrigation infrastructure.

Engineered for Strength & Longevity

Every SM-Series4 unit is constructed with rugged 3-leg support, providing excellent stability even under demanding field conditions. The carbon steel lid with grooved media fill port simplifies service and refilling, while grooved couplings and gaskets ensure secure, leak-free operation.

Inside, you’ll find removable 304 stainless steel wedge wire underdrains, a key differentiator from standard PVC-based designs. This all-metal underdrain eliminates weak points and delivers unmatched durability, corrosion resistance, and consistent water flow season after season.

No PVC. No false bottoms. Just reliable stainless steel performance.

Fast Service & Easy Maintenance

Time is money, especially during peak irrigation season. The side-access manway makes internal inspection, media replacement, and cleaning quick and straightforward. Whether it’s a mid-season check or a full maintenance cycle, growers can easily service the SM-Series4 without downtime or specialized tools.

Built to Withstand the Elements

From scorching sun to high humidity, agricultural environments demand coatings that protect against corrosion and UV degradation. That’s why every SM-Series4 tank is finished with a heavy-duty industrial-grade grey fuze coat, enhanced with UV-resistant additives for superior outdoor durability.

Inside, each tank features an NSF-approved 3M-134 fuze coat lining, ensuring corrosion resistance and water safety, an essential feature for systems handling irrigation, fertigation, or potable water.
