UNSPSC 23152103: Air classification equipment or parts or screens

UNSPSC 23152103 Air classification equipment or parts or screens, a Commodity code, spans detection and measurement devices that state and local governments procure for ambient air quality monitoring, environmental compliance, and field-based pollution assessment. State and local procurement under this code concentrates on specialized analyzers, calibrators, samplers, and support infrastructure for criteria pollutant monitoring networks operated by environmental agencies and regional air quality programs. Recent solicitations show purchasing bodies acquiring equipment ranging from cavity ringdown spectrometers for hydrogen sulfide detection and ozone precursor monitoring systems to portable particulate matter monitors and dynamic dilution calibrators, along with replacement parts, modular shelters, and associated technical services.

Environmental agencies at the state level drive the majority of recent activity, particularly the Texas Commission on Environmental Quality, which has issued multiple RFBs for air monitoring instrumentation and replacement parts since February 2026. The Colorado Department of Public Health and Environment, Michigan Department of Environment Great Lakes and Energy, Georgia Department of Natural Resources, and Kentucky Finance and Administration Cabinet also appear as repeat buyers. Regional councils and special-purpose air quality districts solicit under the code alongside independent school districts and county governments pursuing environmental compliance and field-monitoring capability. Texas leads in recent solicitation volume, with additional activity in Colorado, Michigan, Georgia, Kentucky, and Florida. The Texas Procurement and Support Services TxSMART Buy cooperative purchasing vehicle provides pre-negotiated pricing for indoor air quality equipment to eligible state agencies, universities, and school districts across Texas. Representative recent opportunities include the Texas Commission on Environmental Quality RFB 582-26-15573 for a hydrogen sulfide cavity ringdown spectrometer (due June 10, 2026), RFB 582-26-15508 for dynamic dilution calibrators and zero air supply systems (due April 20, 2026), and RFB 582-26-15242 for specialized Teledyne ozone and flow-control calibrators (due February 25, 2026); the Colorado Department of Public Health and Environment RFP 2026000164 for air monitoring instrumentation and replacement parts to support a 47-site criteria pollutant network (due April 7, 2026); and the Michigan Department of Environment RFP 260000002166 for a modular air monitoring shelter with climate control (due July 1, 2026).
