UNSPSC 47101550: Compression filter

A type of equipment that is to filter the discharged water by penetrating the filter water by applying the water pressure by closing the filtering device.

UNSPSC 47101550 Compression filter (Commodity) represents a narrow product category that state and local governments procure almost exclusively as component parts and replacement units for specialized water and wastewater treatment equipment—not as standalone filtration systems. Recent state and local opportunities show compression filters embedded in sole-source and single-vendor procurements tied to proprietary water treatment infrastructure: drive shafts for softener units, lime-slaking systems, belt press separators, and complementary aeration and chemical-injection equipment at municipal water plants. The work is driven by equipment compatibility constraints; municipalities that install purpose-built water treatment systems from manufacturers like WesTech, Xylem, Chemco, and Andritz become locked into ongoing parts procurement from those vendors because filter replacement units and subcomponents are proprietary and integrated into existing facility systems. Issuing bodies span water and wastewater utilities across a geographically dispersed base—municipal water departments (Holly Hill, Phoenix, Waxahachie, Calhoun, Pompano Beach), county departments of water resources (Gwinnett, Collier, Orange), and regional authorities (West Travis County Public Utility Agency). No repeat buyers dominate the recent pipeline; rather, the code captures ad-hoc replacement and maintenance procurements triggered by equipment degradation or regulatory compliance requirements.

Recent activity concentrates in Florida (Holly Hill, Pompano Beach, Collier County, Orange County) and Georgia (Gwinnett County, Calhoun, Flowery Branch) with scattered activity in Texas and other states. Representative opportunities reflect the embedded-component nature of the code: the City of Holly Hill's sole-source notice (SS202001, due September 22, 2020) procured a replacement drive shaft for softener #2 at its Water Treatment Plant for $113,067, including installation; Collier County's ITB 268705 (due November 13, 2026) solicited countywide chemicals for water treatment across multiple facilities with annual volumes reaching 8,000,000 pounds of sodium hydroxide and other chemical treatment agents; and Gwinnett County's sealed bid for bypass pumping services (BL145-26, due October 23, 2026) sought equipment and labor for maintenance and troubleshooting of water and wastewater infrastructure. The code sees little standalone compression filter activity—most recent opportunities bundle filters with larger treatment system procurements or focus on proprietary OEM parts for systems already in place. Pursue this code only when representing manufacturers or distributors with exclusivity relationships to major water treatment equipment providers or when serving as an OEM authorized parts supplier.
