AirClean is a Seattle-based company founded in 1999. Our original focus was to provide engineering support and process equipment to a core group of customers in the Pacific Northwest.

In 2004, we started targeting our engineering efforts to the industrial energy market. Since then we’ve grown our staff and established our own fabrication facility, giving us the necessary tools to design-build for domestic and international projects. We take pride in our work and hope to create a solution for your company.
