Washington Aluminum purchases the cast Aluminum Industrial Fan Division, and so WACO Fans was born.


The Whispr® Blade makes it's debut




More than 70 years ago, a group of engineers from Koppers Company, who had mastered the aerodynamics of aircraft propellers, applied their knowledge to designing high-quality industrial fans, using the trade name Aeromaster Fans.

From the 1950’s to the 1980's, Koppers developed revolutionary designs and standards that continue to the present day. 

During the 1980's, a subsidiary of Koppers, known as Environmental Elements Corporation, continued to evolve this product line and used the trade name Enelco Fans.  

Washington Aluminum Company purchased the cast aluminum industrial fan division of Environmental Elements in 1989.  The trade name WACO Fans was born.  WACO provided the same high level of quality, dependability, and long-term value on which its predecessors had built their foundation.

The Whispr® Blade was added to the product options in the late 1990’s. Developed by the WACO team, led by Mike Warner, the performance characteristics of the Whispr® Blade were found to be a particularly good fit for the most demanding applications.  Through the success of the Whispr® Blade, WACO Fans became a leader in the Industrial Fan marketplace.

In 2002, Mike Warner and two partners purchased the industrial fan division from Washington Aluminum Company, renaming it Warner Air, LLC. Warner Air, LLC takes pride in the quality of our products and the service that we provide to our customers. 

Over the past 20 years, we have expanded our manufacturing capabilities and footprint, increased our capacity and streamlined the production process, as well as shipping/receiving operations.

In 2020, the world grappled with the onset of the Covid-19 pandemic, yet our role as an essential manufacturer kept our employees coming to work.  The scarcity of PPE at this time led us to expand our 3D-printing technologies and produce over 1,000 reusable masks that were generously donated to local hospital staff and other essential workplaces.

Supply chain challenges continue in 2022 and the Warner Air team has focused on securing raw materials to meet all of our customers’ needs on time. We are also evaluating strategies in our product packaging that aim to reduce/eliminate our dependence on lumber and incorporate reusable packaging.

Our passion is to provide engineering excellence, optimally designed products with rugged heavy-duty construction, and responsive customer service. Our mission is to improve value to customers by continually evaluating and enhancing our processes.
