NIGP 03107: Air Circulation Equipment (Not Otherwise Classified)

NIGP 03107 Air Circulation Equipment (Not Otherwise Classified), an Item code, covers rooftop and building-mounted HVAC package units, exhaust systems, and associated circulation equipment that state and local governments procure for facility replacement, maintenance, and water treatment applications. Recent solicitations show municipalities and regional authorities buying complete rooftop HVAC unit replacements with installation and commissioning (Alameda Housing Authority), preventative maintenance and repair services for chiller and boiler systems serving transit facilities (City of Charlotte), fixed atmospheric monitoring instruments with hazardous-gas detection capability (City of Phoenix Water Services), HVAC filter supplies on an as-needed basis (City of Fort Worth), specialized exhaust system replacements for water treatment labs (City of Tampa), and multi-site water treatment services for heating and cooling systems across state-owned buildings (State of Oregon Department of Administrative Services). Issuing bodies include municipal water departments, transit authorities, county governments, housing authorities, and state administrative agencies, with solicitations spanning replacement of failed or aging equipment, ongoing maintenance contracts, and system optimization work. Cities and special-purpose districts appear as the primary repeat buyers, typically managing large facility portfolios where circulation equipment serves multiple departments or operational functions.

The code sees recent activity concentrated in California (Alameda), North Carolina (Charlotte), Arizona (Phoenix), Texas (Fort Worth and Tampa), Oregon, and Pennsylvania, with additional opportunities posted by county and state procurement offices.
