Nov 5, 2026

Montreal, QC –  Baker Tilly is pleased to announce the successful sale of PAT Technology Systems Inc. (“PAT”) to Fumex Air Filtration Systems (“Fumex”), with Baker Tilly serving as exclusive sell-side advisor.   

Founded in 1998 and operated by co-owners Wayne Baird and Perry Collmer, PAT Technology Systems Inc. is a leading designer and manufacturer of industrial fume extraction and air filtration systems, sold under the Filtrabox brand. With several cutting-edge products, the company serves customers across a wide array of industries in North America and internationally.  

Fumex Air Filtration Systems, a portfolio company of Vance Street Capital, is a leader in air filtration systems, providing advanced extraction solutions designed to meet the stringent health, safety, and regulatory standards required for capturing hazardous materials directly at the source. Fumex’s systems are deployed across a broad spectrum of industrial and healthcare applications, including laser cutting for precision component manufacturing, 3D printing, soldering, and plastic processing.  

Vance Street Capital is a middle-market private equity firm focused on investing in highly engineered solutions businesses across the industrial technology, medical, life science, aerospace, and defense sectors. Vance Street works with management teams and family owners to accelerate revenue growth, improve operations, and acquire strategic assets for the companies in their investment portfolio. 

The combination of Filtrabox with Fumex will allow the business to more effectively serve a global customer base across North America and Europe and the combined engineering resources will be able to develop new products providing innovative filtration solutions to existing and new customers across a broad range of end markets. 

“We are extremely proud of what we’ve built at PAT and grateful to our employees, customers and partners who helped us get here,” said Wayne Baird and Perry Collmer. “Bringing PAT and Fumex together gives us an opportunity to build on what both companies do well, expand into new markets and solve a broader range of customer problems. We are excited about what we can build together.” 

"Wayne and Perry built PAT on a simple idea — bring clean air to the industries that need it most — and they did it by out-engineering the market," said Peter Corio, Managing Director, Baker Tilly Windsor. "Pairing that technology-driven approach with Fumex brings together two leaders, and it gives that mission a much bigger platform to reach more customers and more industries."
