Why Choose Oliver

Our Approach and Technology

Being a third generation manufacturer in North America, the company was established in 1930 by Oliver W. Steele. Son to one of the first developers of the modern gravity separator circa 1897 he helped pave the way for Oliver in the industry. After him, the company was run for 40 years by Oliver’s grandson Geoff O. Burney, and is currently guided by Oliver’s great grandson, Brian Burney.
