Edgewater Strategy Group Supports PX3 Partners on Its Acquisition of Purified Air

LONDON (September 21, 2026) – Edgewater Strategy Group (“Edgewater”), a boutique advisory firm specializing in M&A, capital raises and Office of the CFO services, today announced that it supported PX3 Partners (“PX3”), the London-headquartered pan-European private equity firm, on its acquisition of Purified Air Limited (“Purified Air”).

Founded in 1984 and based in Romford, UK, Purified Air designs, manufactures and services filtration and odour-control systems that remove grease, smoke and odour from commercial kitchen exhaust. The company employs around 90 people and serves many of the world’s best-known quick-service restaurant groups across Europe, the Middle East and the US, as well as a dedicated industrial customer base. Its installed equipment generates recurring service and consumable revenue over the life of each system.

PX3 acquired a majority stake in the family-owned business from its founder, David Collins, who retains a minority shareholding and joins the board as a non-executive director. Long-time executive Andrew James becomes Chief Executive Officer. PX3 plans to support the company’s international expansion, extend its technology into adjacent applications and pursue selective buy-and-build acquisitions.

Edgewater worked as an integrated extension of the PX3 deal team through signing and close, coordinating the buyer’s advisor workstreams, supporting the review of the transaction documents, and managing the lender due diligence process alongside PX3’s investment team and debt financing advisor, Marlborough Partners.

“Purified Air has been built patiently over four decades. Its systems are specified into the kitchens of some of the world’s best-known restaurant brands, and its service model keeps it there for the life of every installation. Working alongside the PX3 team, we tested that thesis from every angle, from the durability of the installed base to the runway for international growth, and our conviction only grew. David and Andrew have built something exceptional, and PX3 brings exactly the experience to take it into its next chapter.”

Along with Edgewater, PX3 was also advised by Alvarez & Marsal, Anthesis Group, Aon, Ashurst Perkins Coie, Confidas People, Debevoise & Plimpton, KPMG and Marlborough Partners. TDC provided committed debt financing. The shareholders of Purified Air were advised by Affinia and Knights. Terms of the transaction were not disclosed.
