About Us

AirClean's roots lie in equipment and process engineering surrounding air-pollution control and boiler systems. Bill Hunter, AirClean's owner, founded the company in 1999. Bill built a base load of customers in the Pacific Northwest providing engineering support and process equipment. In 2004, AirClean received its first design build contract and shortly thereafter began providing industrial, energy-efficient engineering support to the Bonneville Power Administration and its customers. Since then, AirClean has purchased its Seattle fabrication facility and expanded our staff to support our customers domestically and abroad. We appreciate your interest in AirClean and look forward to the opportunity of working with you.
