UNSPSC 23152103: Air classification equipment or parts or screens

UNSPSC 23152103 Air classification equipment or parts or screens is a Commodity code encompassing specialized sensors, monitors, and analytical instruments that state and local governments deploy for ambient and indoor air quality measurement, environmental compliance monitoring, and facility-level hazard detection. Recent state and local solicitations under this code reflect active procurement for Federal Equivalent Method (FEM) certified nephelometers, atmospheric monitoring instruments for hazardous gas detection, environmental conditions monitoring systems, and laboratory-grade air analysis equipment used across environmental quality departments, water and wastewater utilities, school districts, and regulatory agencies. The work spans equipment purchase, calibration systems, replacement parts, technical support, and operator training. Issuing bodies include state environmental quality and agriculture departments, city water and wastewater services divisions, county school districts, and county environmental health programs.

The code sees sustained activity across the Southwest and Southeast, with recent opportunities concentrated in Texas, Oregon, Florida, Arizona, Georgia, Michigan, and Pennsylvania. Representative recent solicitations include the State of Oregon Department of Environmental Quality's request for up to 50 integrating nephelometers certified as FEM under IFB SDASOBO00018179 (bids due November 17, 2026), the City of Phoenix Water Services Department's sealed IFB for atmospheric monitoring instruments-fixed installations across 23 facility types under IFB-27-0435 (offers due September 4, 2026), the Texas Commission on Environmental Quality's RFB for BAM 1022 air monitoring system replacement parts under RFB 582-26-15418 (bids due June 11, 2026), and the Pinellas County School District's ITB for indoor air quality services including asbestos and mold testing and laboratory analysis (ITB #26-CD-039, bids due November 6, 2026). Texas TCEQ issued multiple RFBs for specialized air monitoring equipment including cavity ringdown spectrometers, thermal desorption gas chromatographs, canister samplers, and calibration systems throughout the review period. Award strategies emphasize responsive bidding to published specifications, FEM or EPA method certification where applicable, local parts stocking and same-day or next-day service availability, and multi-year pricing agreements with annual escalation caps.
