Rusco 1-1/2" Spin Down 100 Mesh Inlet Filter (1.5-100-F)

The Rusco 1.5-100-F is a 1-1/2-inch spin-down sediment filter with 100 mesh filtration — a reusable, self-cleaning sediment separator engineered to remove sand, grit, and suspended particulate from water supply lines before that debris reaches downstream equipment, fixtures, valves, and irrigation components that would otherwise be damaged, worn, or clogged by unfiltered sediment in the water supply. Where standard cartridge filters trap sediment in a replaceable element that must be periodically purchased and swapped, the Rusco spin-down design uses centrifugal flow dynamics to spin sediment out of the water stream and collect it in a transparent collection chamber at the base of the filter — where it can be visually monitored and flushed clear in seconds without disassembling the filter body, interrupting system flow, or replacing any consumable element.

The spin-down filtration principle is the defining performance advantage of the Rusco line over standard cartridge sediment filters in applications with meaningful sediment loads. As water enters the filter body tangentially, centrifugal force spins heavier sediment particles to the outer wall of the filter screen and downward into the collection sump — separating sediment from the water stream by mass rather than purely by mechanical screen interception. The result is a filter that handles high sediment loads continuously without the rapid plugging, pressure drop escalation, and frequent element replacement that cartridge filters experience in high-sediment well water, agricultural water supply, and surface water intake applications.

The 100 mesh filtration rating — equivalent to approximately 149 microns — positions the 1.5-100-F as the medium filtration specification in the Rusco mesh range, targeting the sand, grit, and coarse suspended particulate that represents the primary sediment load in well water systems, agricultural irrigation supply, and surface water intakes. At 100 mesh, the filter captures the particle sizes that cause the most rapid wear on pump impellers, valve seats, drip emitters, and spray nozzles — the abrasive particles large enough to score metal surfaces and plug small-orifice components — while passing fine dissolved solids and colloidal particles that are addressed by downstream polishing filtration.

The 1-1/2-inch inlet connection and compact filter body make the 1.5-100-F the correct specification for medium-capacity water supply lines, agricultural irrigation mainlines, residential well pump discharge, and light industrial water supply where 1-1/2-inch is the working pipe size and the filter must fit within the existing piping footprint without major system modifications.

The transparent collection sump provides continuous visual monitoring of sediment accumulation — a practical operational advantage over opaque cartridge filter housings where sediment load and filter condition are invisible until pressure drop symptoms appear. Operators can see exactly when the sump needs flushing and assess sediment load trends that indicate changes in source water quality or upstream system condition.

Rusco has been the professional specification for spin-down sediment filtration in agricultural, residential well water, and industrial water supply applications for decades — the brand that well drillers, irrigation contractors, and water treatment professionals specify when continuous-duty sediment separation without consumable element cost is the design objective.

Specifications

Industries & Applications

The Rusco 1.5-100-F is the sediment separation specification for medium-capacity water supply lines across the full range of agricultural, residential, and light industrial water system applications:

• Residential & Agricultural Well Water Systems — The primary application for Rusco spin-down filters; well water in sand-producing aquifers, gravel-pack wells, and aging well casings delivers continuous sediment loads that rapidly consume cartridge filter elements and cause progressive wear on pump components, pressure tank diaphragms, water softener resin beds, and household fixtures; the 1.5-100-F installed on well pump discharge captures this sediment load continuously without consumable element cost, flushing clear in seconds when the transparent sump shows accumulation.
• Irrigation System Protection — Drip irrigation emitters, micro-spray heads, and pressure-compensating drippers have orifice sizes in the 150–300 micron range that 100 mesh sediment will plug progressively over an irrigation season; the 1.5-100-F installed at the irrigation system inlet on a 1-1/2-inch mainline protects the full emitter and nozzle inventory downstream from the sand and grit load in surface water, pond water, and well water supplies that irrigation systems draw from.
• Pump Protection — Centrifugal pump impellers, submersible pump bearings, and booster pump mechanical seals are abraded and worn by suspended sediment in the water stream; the 1.5-100-F installed on pump suction or discharge intercepts the sediment load before it contacts rotating pump components, extending pump service life and reducing the repair and replacement costs associated with abrasive wear in sand-laden water supply.
• Water Treatment System Pre-Filtration — Reverse osmosis membranes, water softener resin beds, UV disinfection systems, and carbon filter beds are all damaged or fouled by sediment loads that exceed their design tolerance; the 1.5-100-F installed upstream of water treatment equipment as a pre-filter removes the coarse sediment fraction that would otherwise consume treatment system capacity and shorten equipment service life.
• Agricultural Chemical Injection Systems — Fertigation and chemical injection equipment, venturi injectors, and injection pump check valves are sensitive to sediment abrasion and plugging; the 1.5-100-F installed on agricultural water supply lines before injection equipment protects the injection system components from the sediment loads common in surface water and open canal irrigation supply.
• Golf Course & Landscape Irrigation — High-value turf irrigation systems with precision nozzles, rotors, and pop-up heads on golf courses, sports fields, and commercial landscape installations require clean water supply to maintain nozzle performance and precipitation rate consistency; the 1.5-100-F installed on pump station discharge protects the full distribution system from sediment in pond, lake, and reclaimed water supplies.
• Light Industrial Water Supply — Process water supply lines, cooling tower makeup water, and utility water systems in light industrial facilities where suspended sediment in the source water must be removed before equipment contact to prevent wear, plugging, and heat exchanger fouling in water-using process equipment.
• Rainwater Harvesting & Surface Water Intake — Collected rainwater and surface water intakes carry significantly higher sediment loads than municipal or well water supply; the 1.5-100-F provides first-stage coarse sediment removal on rainwater harvesting systems before storage tank entry or downstream treatment, protecting storage infrastructure and treatment equipment from the suspended particulate load in collected surface water.
