HANOVER, MA - Sturtevant Inc., Hanover, MA, announced the sale of its 5,000^th Air Classifier. Air Classifier Number One was sold to Reynolds Tobacco Co. of Winston-Salem, NC, and shipped on September 18, 1919. This early design still has features recognizable today in Sturtevant’s Whirlwind^® Air Classifier, including an internal fan.

“Significant changes have taken place between the shipment of Serial Number One and Number Five-Thousand. Number One was capable of cut sizes in the range of 100 to 325 mesh,” according to Sam Rajkovich, Director of Sales and Marketing. “Number One was innovative for its time, the first internal fan classifier with sharp cut point classification and recirculation, the early predecessor of the Whirlwind^® Classifier we offer today.”

Number 5000, a SuperFine Air Classifier represents a leap in technology. With cut points as low as three micron, it is an ultra-high efficiency classifier.

Sturtevant supplied Number 5000 to its partner Imerys, a provider of mineral-based specialty solutions.

“Sturtevant and Imerys have been partnering for many years, so it is fitting that they helped us reach this amazing milestone. On behalf of the employees and the Sturtevant family, we are all very excited to reach this goal, and we are proud that machines in over 150 countries bear the Sturtevant name,” said Rajkovich.
