UNSPSC 40161700: Separators

UNSPSC 40161700 Separators, a Class code, covers compressed-air treatment and separation equipment — specifically air dryers and related components used in municipal water, wastewater, and utility operations. State and local procurement under this code centers on refrigerated and non-cycling air dryer units, replacement parts including acetal chain and sprockets for clarifier drive systems, and full-service maintenance contracts encompassing preventive and emergency repair support. Issuing bodies are primarily municipal utilities and water/wastewater authorities, with the City of Phoenix Water Services appearing as a repeat buyer in the recent record. The work spans both one-time equipment purchases and multi-year service contracts with strict response and compliance requirements, including DBE participation reporting, E-Verify verification, and port-facility security clearances where applicable.

Recent activity concentrates in Arizona and Connecticut, with the City of Phoenix Water Services issuing two overlapping solicitations for air compressors, dryers, parts, and services — IFB-26-0228 (five-year contract commencing June 1, 2026, with offers due February 25, 2026) and IFB-260359 (supplemental five-year contract commencing September 1, 2026, with offers due June 24, 2026) — both requiring preferred-manufacturer pricing and 24-hour emergency response within two hours on-site. The Town of Killingly, Connecticut Water Pollution Control Authority solicited sealed bids for specialty acetal chain, shear pin sprockets, and chain take-up assemblies (Solicitation 35797, due April 21, 2026). The City of Tampa, Florida issued an RFQ for six Schulz ADS50 Refrigerated Air Dryers (26-P-00274, response deadline April 24, 2026). Phoenix and the broader Southwest have dominated the recent record; Connecticut and Florida represent secondary activity. The Williamson County Purchasing Department notice (26OTHER73) is administrative relocation only and does not constitute a procurement opportunity.
