Oliver is a third generation manufacturer from North America. The company was established in 1930 by Oliver W. Steele, son of one of the developers of the first modern gravity separator, circa 1897. 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.

All along, Oliver has combined durability and efficiency with technological advancements. Like the 1951 multiple-fan design that tripled capacity. And today's Voyager and Maxi-Cap Platinum, the first fully automated, fully integrated gravity separators.

For over 80 years, Oliver has led the way with products for the seed, nut, coffee, recycling, lumber, and mining industries.
