Hartzell exceeds the standard in the industry fan and blower market, committed to delivering top-quality, reliable products. Our relationship with our customers, and our knowledgeable, inventive, flexible and hardworking employees are the reasons we continued and thrived, right here in the USA, for six generations.

Because millions of people around the world breathe the air ventilated by our industrial fans, the quality of our work matters.

Recent years have taught the entire world something we at Hartzell have known for generations: that air quality and proper ventilation are vital to health. In fact, we were one of the industry’s founders‚ designing and engineering our first airfoil blade back in 1927 to improve the safety of our own factory. Because millions of people around the world breathe the air ventilated by our industrial fans, the quality of our work matters. How do we maintain that quality? By staying focused on doing what we’re best at. By assembling our products ourselves, right here in our Ohio plant. By honoring the nearly 150 years of our history, while maintaining our inventive spirit and flexibility. A lot has changed in the world in the six generations since John T. Hartzell founded our company. Our commitment to quality never will.



Our mission is to manufacture reliable, quality industrial fans and blowers through hard work and innovation.


Our vision is to create healthier, safer working environments around the world through reliable, high-quality, industrial fans and blowers.
