Rusco® Spin-Down® Sediment Filter - 1.5in - 140 Mesh

1.5in Cyclonic Spin-Down Filter for Sediment-Heavy Water Sources

Well water, geothermal loops, and agricultural supply lines often carry sand and silt that pumps, emitters, and sensitive equipment weren't built to handle. Rusco's Spin-Down filter tackles that at the 1.5in connection size using a cyclonic spin action that forces incoming sediment to the bottom of the housing, catching it on a 140-mesh screen before it reaches anything downstream.

Because sediment collects at the bottom, purging it is as simple as opening the flush valve, no system shutdown or filter disassembly required, which makes this filter as practical for a well pump as it is for lawn and turf, livestock feeding systems, or industrial liquid cooling.

Key Features & Benefits

• 140 mesh filtration — captures particles 105 microns and larger, including sand and silt.
• 1.5in connection — suits medium-to-high flow irrigation and industrial applications.
• Spin-Down purge design — sediment collects at the bottom and purges via the flush valve without interrupting flow.
• Versatile applications — suited to household well water, geothermal HVAC, drip irrigation, livestock systems, and industrial cooling.
• Durable construction — built for long service life in demanding filtration environments.

Who Should Use This

Growers, irrigators, and facility managers who need reliable sediment pre-filtration for pumps, drip systems, misters, or other sensitive water-using equipment on a 1.5in line connection benefit from the Spin-Down's cyclonic design and easy purge process.

About Rusco

Rusco was founded in late 1983 by Russ Welte, who set out to build a more efficient inline sediment filter after running into the limits of what the filtration industry offered at the time. The company trademarked its cyclonic Spin-Down design in 1986 and remains a family-owned, USA-manufacturing operation more than 40 years later.

Frequently Asked Questions

How does the Spin-Down design work?

Water enters the housing tangentially, creating a cyclonic spin that forces sediment to the bottom rather than letting it settle across the screen. Opening the purge valve flushes that collected sediment out without needing to shut the system down or remove the filter.

What size particles does the 140-mesh screen capture?

The 140-mesh screen captures particles around 105 microns and larger, which covers sand, silt, and similar suspended solids common in well water and agricultural supply lines. Finer particles that pass through the screen are typically handled by downstream filtration stages if further clarity is needed.

How often should I purge this filter?

Purge frequency depends on how much sediment your water source carries; a well with heavy sediment may need purging weekly, while cleaner municipal-adjacent sources can go longer between purges. Watching for a pressure drop is a good practical trigger to purge.

What replacement screen does this filter use?

This filter uses the Rusco RUSCOFS1-1/2-140 polyester replacement screen element, matched to its 1.5in - 140 mesh specification. Replace the screen when it's torn, permanently clogged, or deformed.

Is this filter suitable for livestock watering systems?

Yes, the Spin-Down filter's versatility extends to livestock feeding systems in addition to well water, geothermal, irrigation, and industrial cooling applications. Its 1.5in connection handles the flow demands typical of those setups.
