Studor

What Studor does

Studor is a brand within the Aliaxis group of companies, operating as a specialized provider of active drainage ventilation solutions for commercial and residential buildings. Founded in 1974 and registered in Douglas, Isle of Man, the company develops pneumatic valve-based systems that manage air pressure fluctuations within building drainage networks, eliminating the need for traditional roof penetrations and extensive vent piping. Its technology is organized around four primary use cases: low-rise buildings (Maxi-Vent avoids roof penetrations and preserves insulation), medium-rise buildings up to 12 levels (Mini-Vent counters induced siphonage on horizontal branches), high-rise buildings above 12 levels (P.A.P.A. dampens positive pressure, combined with Mini-Vent and Maxi-Vent for a complete system), and retro-fit applications (Air Admittance Valves resolve slow drainage, gurgling, odors, and trap seal depletion in existing buildings).

Studor's product portfolio consists of four core hardware products—Maxi-Vent, Mini-Vent, P.A.P.A. (Positive Air Pressure Attenuator), and Air Admittance Valves—which collectively form a complete active drainage ventilation system. Revenue is generated through hardware sales of these valves and bundled systems; specific pricing is not publicly disclosed and is handled via sales-team quotes. Distribution occurs exclusively through Aliaxis's International Business Development team, which reaches more than 140 countries, with regional sales managers (notably Daniel Rath as Studor International Sales Manager) engaging directly with architects, MEP consultants, contractors, and installers. Marketing and specification support are delivered through the Aliaxis International website, a Building Information Modeling (BIM) library, and direct enterprise field sales. As a privately held brand within the privately owned Belgian parent Aliaxis SA/NV (approximately 15,500 employees, 40+ countries of direct operation), Studor operates without standalone financial disclosure, independent funding events, or its own public-facing executive team beyond an international sales function.

Core offering

Studor designs, manufactures, and sells active drainage ventilation valves and systems (Maxi-Vent, Mini-Vent, P.A.P.A., and Air Admittance Valves) for commercial and residential buildings. The products use pneumatic valve technology to control air pressure fluctuations in plumbing systems, eliminating the need for roof penetrations and extensive group vent piping. Solutions are tailored by building height category—low-rise, medium-rise, high-rise, and retro-fit applications.

Product overview

Studor is a brand under Aliaxis that provides active drainage ventilation solutions for commercial and residential buildings. The product portfolio consists of specialized valves and systems including Maxi-Vent (for low-rise building roof penetration avoidance), Mini-Vent (for medium-rise building negative pressure control), P.A.P.A. (Positive Air Pressure Attenuator for high-rise positive pressure dampening), and Air Admittance Valves (for retro-fit applications). Together, these products form a complete active drainage ventilation system that eliminates the need for roof penetrations and extensive group vent piping, providing maintenance-free drainage systems that limit pressure fluctuations and guarantee trap integrity.
