Keystone designs and manufactures a range of filter cartridges and housings for the food and beverage, drinking water and chemical process markets in the U.S.
Keystone reported revenue of approximately $4 million in the year ended December 31, 2017. As part of this acquisition, the group has entered into a transition services agreement with CECO to transfer the business to its plant in Ashland, VA, over the next few months.
Ben Stocks, chief executive of Porvair plc, says: "The acquisition of Keystone increases [our] presence in the U.S., broadening [our] markets and providing a range of cross selling opportunities. Keystone brings sales expertise, distribution and a broad customer base for whom Porvair's wider product range will be attractive."
