Industrial Division

Our Industrial Division is focused on engineering and manufacturing premier system components for dry bulk material processing equipment, pneumatic conveyors, and dust collectors. We are recognized for our superior Rotary Airlock Valves, Sanitary Airlock Valves, Double Flap Gate Valves, and Pneumatic Screw Pumps that handle your toughest application. We also manufacture Gravity Diverters, Slide Gates, and Blower Packages. No other company offers every system component for air process/bulk material handling systems under one roof like we do.

Our Beginning

1976During the 1920s, William W. Meyer, Sr. worked for Roots Blower in Connersville, Indiana. He was a hard-working employee, but he dreamed of owning his own business. So in 1933, armed with his experience servicing blowers and pumps, Bill Meyer set out on his own. His new venture, General Blower Company, began manufacturing centrifugal fans for industrial ventilation, pneumatic conveying, dust collection, and gas boosting in Chicago, Illinois.

Despite the Depression and World War II, Bill Meyer’s business continued to succeed. Developing new product lines that included insulation blowing machines and vacuum collection systems, General Blower had become an equipment manufacturer in its own right.

In 1946, a subsidiary business, Meyer, was established and began offering equipment services from a small shop in Skokie, Illinois. In addition to service, Meyer purchased used air-moving equipment, rebuilt it, and then sold it for substantially less than the cost of new equipment. Also, to give customers the option of purchasing new equipment, Meyer became an agent and distributor for other manufacturers including Sutorbilt Blower (known today as Gardner Denver).

Meyer HistoryIn 1959, General Blower was sold and Meyer continued to manufacture dry bulk material processing equipment, dust collectors, rotary airlock feeders, insulation blowing machines, and vacuum collection systems from their current location in Libertyville.

Today, Meyer & Sons, Inc., is a world leader in the manufacture of dry bulk material processing equipment, pneumatic conveyors, dust collectors, insulation blowing machines, and vacuum collection systems.

By continuing Bill Meyer’s tradition of developing innovative machinery and committing to the highest standards of quality, craftsmanship, and customer service, the company he founded has continued to grow steadily into its second, third, and now the fourth generation of family ownership.

Meyer Racing

Meyer Racing is more than just racing; it’s our way of expressing ourselves as a company. We choose to be bold. We choose to stand out. We choose to be a part of something that is more than just what we manufacture. Racing enabled us to reach out to communities beyond our Libertyville home and give back to charities that have done so much for so many. To us, racing embodies fun, excitement, and camaraderie. We invite you to follow Wm. W. Meyer & Sons and Meyer Racing as we “drive” for the championship.

Meyer Cares

HFHNFV LogoWe strongly believe in building and supporting our community and the communities around us. Each year, Meyer supplies and installs insulation in houses for Habitat for Humanity. With each project, Meyer encourages its employees to spend the day installing insulation to not only learn about our product but also experience the joy of providing to those in need.



Meyer has participated in the Toys for Tots program since 2010. As a family company, we firmly believe in investing in our most valuable resource, our future generations. By partnering with McHenry Harley-Davidson, Meyer maximizes its positive impact, encourages community collaboration, and ensures a fun experience for all. Each year, Meyer employees donate over two truckloads of toys to the Marines who then distribute the donations to hospitals, orphanages, and needy children.
