Desjoyaux pipeless filtration: 40 years of innovation (1983-2026)
Desjoyaux pipeless filtration: 40 years of innovation (1983-2026)
Posté leIn 1983, Piscines Desjoyaux revolutionized the swimming pool industry with pipeless filtration. This patented technology, inspired by outboard boat engines, radically transformed the design of swimming pool filtration systems.
Forty years later, this innovation remains at the heart of the success of the world leader in in-ground swimming pools .
The nautical inspiration behind an innovation
The story begins with a brilliant observation by Jean Desjoyaux. Boat outboard motors operate without complex piping, drawing in seawater directly. This nautical approach inspired a revolutionary filtration system that eliminated traditional buried pipes.
The Desjoyaux filtration system integrates all equipment into a compact, single-unit system. This design eliminates the risk of underground leaks and simplifies installation. The traditional technical room is no longer necessary thanks to this patented innovation that positions the filtration system directly on the pool structure.
How does Desjoyaux's pipeless filtration system work?
The system is based on a simple yet effective principle. The filtration unit is mounted on the pool wall or integrated into the structure. This one-piece filtration system consists of two compartments, each containing all the necessary filtration components: the technical compartment/room houses the filtration pump, and the filter compartment/room houses the skimmer, pre-filter basket, filter media, and lights. Suction and return pipes connect the two compartments and ensure water circulation.
Water is drawn from the skimmer into the filter room and, once filtered, returns to the pool through the return jet. The exclusive Desjoyaux filter media, typically a filter bag available in 6, 15, and 30 microns, ensures optimal water filtration.
Cleaning the filter media consumes only 36 liters of water per cleaning compared to 750 liters for conventional sand filtration systems during backwash (sand filter washing).
As Johann V. de Saint-Folquin testifies: "Your filtration system is far superior to the sand I used for years." The filtration blocks adapt to all swimming pools, private as well as public, offering remarkable installation flexibility.
40 years of technological evolution (1983-2026)
Since 1983, Desjoyaux has been constantly improving its pool filtration systems. The company invests in research and development to maintain its technological lead in the face of market changes and environmental requirements.
Modern filtration units offer a sleeker design, are equipped with LED spotlights, and can accommodate options such as salt chlorinators with automatic pH regulation, counter-current swimming systems, and heating systems. This evolution transforms the simple filtration unit into a true intelligent control center for the pool filtration system.
Innovation goes hand in hand with an environmental commitment. Pipeless filtration consumes half the energy of a traditional system due to the absence of pressure losses. This performance aligns with the company's environmental approach, which will enable it to recycle 5,000 to 6,000 tons of plastic annually at its Saint-Étienne plant starting in 2026.
The exclusive advantages of the Desjoyaux system
Pipeless pool filtration offers tangible practical advantages. The absence of buried pipes eliminates the risks of freezing and underground leaks. This technical security provides peace of mind for homeowners and simplifies maintenance.
Marie Hélène J. from Osny confirms this reliability: "We are very happy with the pool and the heating, and we've never had a breakdown" after 15 years of use. Installing a pool without piping proves to be faster, reducing construction time so families can enjoy their pool sooner.
The pool filtration system adapts to space constraints. Without the need for a technical room, garden design gains creative freedom. This architectural flexibility appeals to owners of small urban plots.
The impact on the global swimming pool industry
With 400 points of sale in 80 countries and €98 million in revenue projected for 2025, Desjoyaux has established itself as the world's leading network for the construction of in-ground swimming pools. This international success is based on the company's investments in improving the quality of its production.
The company produces 8,000 swimming pools per year in its French factory, which is one pool every hour. This industrial capacity, combined with French expertise, has guaranteed consistent quality for four decades.
The system's effectiveness is confirmed in daily use.
As one owner explains: "Our pool is 7m x 3.5m and the filtration unit does its job very well, in addition to being easy to use." Desjoyaux filtration influences the entire sector, remaining a unique patented technology after forty years of continuous improvement.
