UNSPSC 40161511: Coalescing filters

UNSPSC 40161511 Coalescing filters is a Commodity code for separation and filtration equipment that state and local governments procure primarily for wastewater treatment, industrial operations, and specialized machinery maintenance. Recent solicitations show state and local buyers purchasing coalescing filters as replacement components for treatment systems, mixers, and environmental equipment rather than as standalone products. The issuing bodies span municipal utilities, county utilities departments, and cooperative purchasing vehicles that aggregate demand across multiple jurisdictions. Work solicited under this code includes replacement parts for existing equipment, maintenance consumables, and integrated filtration modules bundled with treatment machinery.

Activity under the code is geographically dispersed across the Pacific Northwest and Southeast. The City of Salem, Oregon solicited a Puma 2400 ECO Machine (a coalescing filtration system) under sole-source authority in July 2026 with a contract value of $424,494.70 and response deadline of July 15, 2026. Pinellas County Utilities in Florida issued an ITQ for Invent Mixer Parts & Accessories with performance spanning Pinellas County and Clewiston City, due June 30, 2026, suggesting a continuation of prior blanket purchase agreement activity. A State of Minnesota cooperative purchasing vehicle (Sourcewell) issued RFP #061626 in May 2026 for Law Enforcement Equipment with a June 16, 2026 deadline, though this entry appears misclassified under the code and does not represent relevant coalescing filter procurement. Recent opportunities reflect replacement-component and system-upgrade procurement cycles rather than new-build infrastructure, with compressed proposal windows typical of continuation or renewal procurements tied to existing equipment maintenance schedules.
