UNSPSC 40151603: Diaphragm compressors

UNSPSC 40151603 Diaphragm compressors (Commodity) encompasses trailer-mounted and skid-mounted air compressors powered by diesel rotary screw engines, which state and local governments procure for road maintenance, emergency response operations, and field construction work. Recent solicitations show state transportation and public safety agencies buying new equipment meeting Federal, OSHA, and ANSI safety standards, with specifications typically calling for 250–375 cfm capacity at 100–150 psi, including integrated hose reel assemblies, tool lubricators, and operator-control panels. Issuing bodies include state departments of transportation, county public safety commissions, and regional cooperative purchasing vehicles serving multiple jurisdictions. No minimum purchase quantities are guaranteed in current solicitations, and vendors must be established manufacturers or authorized dealers; remanufactured or reconditioned units are not acceptable.

The Illinois Department of Transportation posted a rebid for trailer-mounted air compressors (IFB B49477, due July 20, 2026) covering Districts 1–4, requiring firm pricing for 180 days and manufacturer warranties of at least twelve months with F.O.B. destination delivery weekdays 8:00 a.m.–2:00 p.m. Illinois applies preference for U.S.-manufactured products at comparable pricing and quality. Hillsborough County, Florida (Board of County Commissioners) issued an ITB on July 7, 2026 (due July 24, 2026) for janitorial and operational supplies serving the Fire Rescue Department, estimated at $765,679.84 annually, though the posting conflates commodity coding and the specific diaphragm-compressor scope is unclear in that record. Sourcewell, a Minnesota cooperative purchasing vehicle, posted RFP #061626 on May 12, 2026 (due June 16, 2026) for law enforcement equipment, which does not specify air-compressor inclusion in the available documentation. Recent activity appears concentrated in Illinois and Florida counties, with Sourcewell representing a multi-state cooperative contracting framework. Vendors must maintain active registration in relevant state procurement systems and carry general liability insurance ($1 million per occurrence minimum).
