NIGP 82005: Air Dryers, Dehydrators, and Preheaters

NIGP 82005 Air Dryers, Dehydrators, and Preheaters, an Item code, covers equipment that removes moisture from compressed air systems and preheats inlet air for industrial and municipal operations. State and local governments procure these units for compressed-air infrastructure at water treatment facilities, wastewater plants, fleet maintenance shops, and public works operations where air quality and system efficiency directly affect equipment life and operational cost. The equipment ranges from standalone cartridge and desiccant dryers to integrated preheating assemblies that condition air before it enters downstream pneumatic or processing systems. Issuing bodies include state departments of transportation and environmental protection, county public works and utilities departments, city water and wastewater divisions, and transit authorities managing compressed-air-dependent vehicle maintenance facilities.
