Réduction 200/100 symétrique galvanisée avec joint RSOCU200100

Application in ventilation and air conditioning systems

This component enables a smooth transition between ducts of different diameters, in this case from 200 mm to 100 mm, which is crucial when connecting sections with varying airflow capacities. Thanks to the integrated EPDM rubber gasket, the connection is airtight and resistant to air leakage, directly enhancing the overall efficiency of the installation. The material of construction – galvanized steel – ensures corrosion resistance under standard operating conditions, while air tightness class D guarantees that the system will perform according to design specifications even at higher flow velocities.

Compatibility and installation

The reducer has been designed to fit the most common types of flexible and rigid ducts used in the HVAC industry. It can easily connect elements of systems such as:

• THERMOFLEX
• SONODUCT
• SPIRO
• FLEX
• ALUFLEX

The built-in gasket eliminates the need for additional sealing tapes or adhesives at the joint, speeding up installation and reducing the risk of workmanship errors. This is a universal solution – suitable for both mechanical ventilation systems and heat recovery units, as well as for connections to fireplaces.

Compliance with standards and legal requirements

A key aspect of this product is its compliance with current legal requirements for ventilation installations. The component bears the "B" mark, which is mandatory for products placed on the market after June 30, 2019. This ensures that installers can be confident they are using components meeting the rigorous safety and quality criteria required by Polish and European regulations.

Key technical parameters of this model include a symmetrical reducer with dimensions 200/100 mm, made of galvanized steel with an EPDM gasket (RCPL). The product features air tightness class D, confirming its suitability for demanding ventilation and air conditioning installations.
