Aerovent, a company of quality, stature and endurance, began in 1932, as Piqua Electric Manufacturing. This tiny Midwestern fabricator, who produced "aeroplane propeller" industrial fans, fought to secure a foothold in the emerging air moving and ventilation market through quality products with innovative features. Seven decades have passed and the Aerovent line has become the symbol of quality air handling equipment in every industry. Advanced engineering, accurate and dependable ratings, and fully guaranteed performance have served as our guide in the development and manufacture of excellence and serviceability.

Strengthened by our roots, deeply planted in knowledge and experience, Aerovent is setting the industry standard, and the competition is following suit. A new manufacturing facility and a dedicated work force of highly skilled and committed employees keep Aerovent at the forefront in fan manufacturing. An AMCA registered test laboratory assures that Aerovent remains the quality leader in the field of air moving and ventilation equipment. A knowledgeable representative sales force insures that the right product is matched to each application - every time.

Aerovent's primary manufacturing site sprawls over 145,000 square feet in Aberdeen, South Dakota. We also have sites in Mitchell, Elkton and Brookings, South Dakota, as well as Covington, Ohio. Our facilities utilize state-of-the-art equipment and innovative manufacturing processes but it is the people who work here - their skill, their knowledge, and their commitment to build the best fans in the world - who make Aerovent a leader in the industry. Aerovent has provided quality air moving and ventilation equipment for over seventy years. The highest quality materials, the most advanced equipment and techniques, and complete in-house fabrication all contribute to a product line unsurpassed in the air moving industry. Continued research and development of innovative designs also help Aerovent maintain their leader status.
