NIGP 03108: Air Curtains

NIGP 03108 Air Curtains, an Item code, addresses entrance and vestibule climate control equipment that state and local governments procure to maintain indoor air quality and thermal efficiency at facility access points. The scope covers motorized air curtain units installed above doorways and openings to create an invisible barrier that prevents unconditioned air infiltration while allowing pedestrian and vehicle traffic. State and local issuing bodies soliciting under this code include county purchasing departments, municipal facilities management offices, and special-purpose districts managing public buildings, warehouses, and service facilities. The equipment serves both new construction and retrofit applications across government buildings, transit facilities, and institutional properties.

The available recent-opportunities block contains no active solicitations for air curtain equipment. One record (Williamson County Purchasing Department, July 2026) is a relocation notice with no procurement scope. A second record (Sourcewell RFP #061626, due June 16, 2026) addressed law enforcement equipment through a cooperative purchasing vehicle and does not reference air curtains. Without sourced recent activity, no geographic concentration, issuing-body frequency pattern, or representative opportunity can be credibly characterized for this code at this time.
