NIGP 02570: Moisture Separators, Non-Refrigerated

NIGP 02570 Moisture Separators, Non-Refrigerated, an Item code, covers air dryers and moisture separation equipment that state and local governments procure for compressed air treatment and industrial applications across water treatment facilities, wastewater plants, and municipal operations. The solicitations posted under this code show purchasing activity for both standalone air dryer units and bundled compressor-dryer-parts-and-service contracts, typically awarded as multi-year agreements with firm fixed pricing, manufacturer-preferred specifications, and compliance requirements for preventive and emergency maintenance support. Issuing bodies include major city water and wastewater departments, with the City of Phoenix Water Services emerging as a repeat buyer soliciting five-year contracts for stationary air compressors and dryers supporting treatment infrastructure.

The City of Phoenix, Arizona dominates recent activity under this code, posting two solicitations—IFB-26-0228 (posted March 5, 2026, due February 25, 2026) and IFB-26-0359 (posted June 24, 2026, due June 24, 2026)—for air compressors, dryers, parts, and services across multiple water treatment and wastewater facilities, each spanning five-year terms. The City of Tampa, Florida issued RFQ 26-P-00274 (posted April 27, 2026, due April 24, 2026) for six units of Schulz ADS50 Refrigerated Air Dryers for one-year award across city departments. Phoenix's solicitations emphasize local inventory maintenance, 24-hour emergency response within 30 minutes by phone and two hours on-site, DBE compliance under 49 CFR Part 26, and pricing structured as percentage discounts off manufacturers' lists for preferred vendors including Atlas Copco, Kaeser, Sullair, Ingersoll Rand, Quincy, and Zeks, with minimum $2 million general aggregate liability insurance required.
