公司历史

Porvair Filtration Group, a wholly owned subsidiary of Porvair plc, is a specialist filtration and environmental technology group involved in developing, designing and manufacturing filtration and separation solutions to industry sectors such as the aviation, molten metal, energy, water treatment and life sciences markets. Porvair plc is a publically owned company with four principal subsidiaries: Porvair Filtration Group Ltd., Porvair Sciences Ltd., Selee Corporation and Seal Analytical Ltd.

Porvair Filtration Group has grown organically and through acquisition and incorporation of a number of specialist filtration and engineering companies. Each of these companies brought specific capability and technology to broaden our offering to customers or improve our value proposition. A number of these acquisitions have grown up to form our UK operating divisions located in Segensworth, New Milton and our Porvair Filtration Group Inc. operations in Virginia, Boise and Maine in the USA.
