UNSPSC 40101608: Fan filter unit

A device designed to filter interior and exterior air flows on an air conditioner.

UNSPSC 40101608 Fan filter unit is a Commodity code covering replacement filters, exhaust systems, and related components that state and local governments procure for HVAC, water treatment, and facility ventilation infrastructure. State and local buyers soliciting under this code include city water and wastewater departments, transit authorities, general services/facilities departments, and multipurpose public agencies. The scope of recent activity centers on replacement HVAC filters for municipal buildings, specialized atmospheric monitoring equipment with fixed sensors for confined spaces and lift stations, and complete exhaust system replacements at treatment facilities—work that typically requires vendor certifications, maintenance of local replacement-parts inventory, and rapid-response capabilities. Issuing bodies range from city procurement offices (Fort Worth, Phoenix, Tampa, Charlotte) to state-level facilities management (Oregon Department of Administrative Services) and county facilities departments.

The most recent opportunities show activity concentrated in the Southwest and Southeast, with notable solicitations posted in Texas (Fort Worth RFP 26-0262 for HVAC filters due September 3, 2026; Tampa IFB 26P00430 for Strobic Air exhaust system replacement due September 14, 2026), Arizona (Phoenix IFB 270435 for atmospheric monitoring instruments due September 4, 2026), North Carolina (Charlotte RFP 26920271769 for boiler and chiller maintenance due October 15, 2026), and Oregon (State RFP S1070000017049 for water treatment services across multiple DAS facilities due October 5, 2026). The City of Fort Worth procurement exemplifies current buying patterns—an as-needed supply agreement with a 30% small-business participation goal, covering antimicrobial pleated filters (minimum MERV 8), rigid box filters, bag filters, and HEPA filters with 24-hour rush-order capability required, awarded to Air Relief Technologies Inc. in December 2021 and now re-solicited. The Phoenix and Tampa solicitations emphasize manufacturer-specific equipment (Drager, MSA, De Nora, Strobic Air) requiring certified technicians, local parts stocking, and compliance with transit authority DBE and small-business set-asides. Geographic activity clusters around municipal water and transportation infrastructure modernization in growth-region metros.
