Ingersoll Rand Celebrates 90 Years of ARO

Ingersoll Rand’s ARO® brand provides fluid handling products for industries around the globe, including chemical, manufacturing, energy, pharmaceutical, mining and more—and, in 2020, Ingersoll Rand celebrates 90 years of ARO! When  ARO Equipment Corporation was founded in 1930 in Bryan, Ohio, original products included grease guns, couplings and automotive lubricators for use in service stations. Today, our positive displacement pumps are expertly engineered for performance and reliability. ARO® diaphragm pumps, piston pumps, lubrication equipment, filters, regulators, pneumatic valves and actuators deliver the best total cost of ownership on the market and help customers get the most from their compressed air systems.

As I reflect on ARO’s ninetieth anniversary, there is no doubt our employees are our greatest asset,” said Jonathan Wiechers, ARO vice president, global sales. “Companies do not survive—much less thrive—for nine decades without great people. It’s our people that make this company and brand great.”
