What The Maddocks Group does

The Maddocks Group is a privately held Canadian manufacturer of industrial filtration products, established in 1979 and headquartered at 663 Woodward Avenue, Hamilton, Ontario. The company designs and produces custom and replacement filter bags, filter cartridges, pleated filter elements, HVAC filtration products, blower/air intake filters, and filter cages/accessories for industrial dust collection and air filtration applications. Its proprietary Beane™ Bag technology features a seamless tube circular knit construction with a patented loop pile surface delivering 99.5–99.9% filtration efficiency, complemented by a trademarked Static Eliminator media that grounds static charges in hazardous dust environments. Other differentiating features include the Dimple Open Pleat design, Pleat Lock cellulose folding, and Wire Back cartridge construction.

The company's product portfolio spans multiple media types (polyester spunbond, cellulose, needlefelt, PTFE membrane, and proprietary knitted fabrics) and serves horizontally across industries including cement, steel, woodworking, food processing, pharmaceuticals, mining, automotive, paper, grain/flour, tobacco, foundry, and commercial HVAC. Revenue is generated through one-time unit sales on a quote-based pricing model, with customers submitting detailed technical specifications (temperature range, dimensions, media type, air flow, construction details) for custom manufacturing. The company operates a direct sales model from a single Hamilton, Ontario manufacturing facility, with sales staff including Maryann Murney and toll-free North American support, and no disclosed intermediaries, channel partners, or digital marketing infrastructure.

The Maddocks Group maintains OEM-compatible replacement products for major dust collector brands including AAF, Dustex, Murphy/Rodgers, Torit/Donaldson, Farr, Pangborn, UAS, Wheelabrator, Nordson, MicroPul, and FlexKleen. The business is owner-operated with 11–50 employees, no disclosed parent company, no institutional investors, and no venture capital backing, and has remained independent since inception.
