Specialist filtration, laboratory and environmental technology group Porvair has agreed to acquire German aluminium filtration specialist Drache Umwelttechnik GmbH for £17.8 million.

Founded in 1984, Drache designs and manufactures filters, consumables and equipment for the molten metal industry and will join the Cambridge firm’s Metal Melt Quality division, adding a European operational base.

The deal, which includes two freehold sites in Germany, is expected to boost earnings in the year to November 2026, with Drache generating over £17m of revenue in 2025.

The acquisition is being funded from existing cash and facilities and is expected to complete later today.
