Réduction 315/200 symétrique galvanisée avec joint RSOCU315200

Application and functionality in ventilation systems

This component enables a smooth transition between ducts with diameters of 315 mm and 200 mm in mechanical ventilation installations. Thanks to its symmetrical design, installation is simplified, and the joint maintains geometric stability, which is crucial when connecting SPIRO, FLEX, or ALUFLEX type ducts. The built-in EPDM rubber gasket (RCPL type) eliminates the need for additional sealing tapes at the joint, accelerating the installer's work and guaranteeing Class D air tightness. Such tightness means that the system does not lose air at connections, resulting in lower energy consumption by fans and maintaining designed flow parameters.

Material and resistance to operating conditions

The product is made of galvanized steel sheet, providing natural corrosion resistance in typical indoor conditions. The galvanization acts as a protective barrier against moisture contained in the ventilation air, extending the fitting's service life without the need for additional painting. The total weight of the component is only 0,86 kg, facilitating transport to higher floors and overhead installation without the need for heavy supporting equipment. External dimensions (approximately 0,33 m in length) allow for easy adaptation to standard mounting frames or hangers.

Compliance with regulatory requirements

A key aspect of this model is the possession of the "B" mark, which is mandatory for ventilation components placed on the market after June 30, 2019. This means that the reducer meets rigorous requirements regarding fire reaction and fire safety in buildings. For designers or supervision inspectors, this is proof that the component can be legally used in installations requiring fire certification.

The reducer directly connects ducts with diameters of 315 mm and 200 mm, while maintaining air tightness class D. The entire assembly is made of galvanized steel with an EPDM rubber gasket (RCPL), ensuring durability in the ventilation environment. The component complies with required standards ("B" mark) and weighs approximately 0,86 kg, facilitating handling during installation works.
