In 1930, John Markey founded ARO Equipment Corporation in Bryan, Ohio. ARO’s original product lineup included grease guns, couplings, and automotive lubricators. After only six short years, they surpassed $1 million in sales, thanks to John’s original mission: create quality products that make people proud.

During ARO’s first sixty years in business, there were plenty of milestones worth celebrating. Products were expanded to include necessary items for war production, including oxygen regulators, vacuum pumps, grinders, and drills. Soon after, ARO products slowly expanded beyond American soil and headed to Switzerland, Belgium, Mexico, and North Wales, and more. Finally, twenty-two years after ARO pumps made their way into space, the pitboss pump was launched–the first choice for general industrial, mining, and construction professionals worldwide.

Present-day, ARO is a leading global manufacturer of fluid handling equipment, serving various industries worldwide. Their filters, regulators, lubricators, pneumatic valves, and actuators help customers get the most from their compressed air systems. ARO is a leading brand of Ingersoll Rand.
