Airoflex has been supplying the industry standard for hydraulic truck and trailer dumpers since 1947.

We are dedicated to providing durable, reliable, and quality built equipment.


What sets Airoflex apart from our competitors? We have been building equipment since 1947 and have dumpers that are still operating after 50 years. No other company can make that claim. When you purchase an Airoflex standard pivot or extended arm truck dumper, trailer tipper, receiving hopper, or hydraulic cylinder, you know you are buying proven quality.

Airoflex dumpers and hoppers are 100% bolted connections. Everything is pre-fit and match marked in our shop prior to shipment to ensure ease of installment. Consequently, this significantly reduces installation costs, time, and resources. The bolted connections also allow for easy field replacement in the event of damage or wear.

Performance is built into the price of every piece of Airoflex Equipment we manufacture. We do not offer second-rate options with hopes of upgrading you to more expensive ones later. This is because we have considered your long-term operational costs, not just the sticker price.

Another unique Airoflex benefit is our unparalleled after-sale customer service and support. We provide an extensive in-stock inventory of spare parts. Furthermore, we also provide cylinder repair and rebuild, an exchange program for qualified cylinders, and additional services. These services include commissioning, startup, inspections, and testing. We truly go the distance for our customers.

A Brief History

Airoflex Equipment has been supplying innovative engineering concepts for hydraulic truck dumpers and tippers since 1947. On April 27, 2010, Hoffmann Inc., a nationally recognized leader in industrial construction, steel fabrication and material handling systems, announced the acquisition of Air-O-Flex Equipment Co. of Roseville, Minnesota. Air-O-Flex Equipment is now manufacturing under the company name Airoflex Equipment. However, our company has retained the same dedication to quality-built products.

Our products have not only been installed throughout the United States, but also Canada, Mexico, Central America, South America, and in the Middle and Far East. Products have been used in the biomass, municipal solid waste, pulp and paper, energy generation, cogeneration, food processing, rendering, and recycling industries. Additionally, Airoflex can supply truck dumpers and trailer tippers for an even wider range of industries.
