Symmetrical galvanized reducer 125/100 with gasket RSOCU125100

Application and Functionality in Ventilation Systems

This component connects ducts with a diameter of 125 mm to pipes of 100 mm, which is crucial when transitioning between different sections of the installation or connecting devices with smaller outlets. Thanks to its symmetrical design and galvanized steel coating, the reducer is suitable for mechanical ventilation systems, air conditioning, and heat recovery installations. It is compatible with popular types of flexible and rigid ducts used in ventilation systems.

A key feature is the factory-installed EPDM rubber gasket (RCPL). This solution eliminates the need for additional sealing tapes during installation, speeding up the installer's work and ensuring airtightness immediately after fitting the component. Sealing class D confirms that the product meets the requirements for standard ventilation installations.

Compliance with Standards and Operational Safety

The product bears the conformity mark „B", which is a legal requirement for ventilation components placed on the market after June 30, 2019. Possession of this marking is essential during project handover and ensures compliance with current construction regulations and safety standards.

The material of construction – galvanized steel – provides corrosion resistance under conditions typical for residential and public buildings. The EPDM gasket is characterized by durability and flexibility, allowing compensation for minor dimensional deviations of pipes and absorption of vibrations transmitted through the installation.

Construction and Practical Mounting Benefits

The component is designed as a symmetrical reducer made of galvanized steel, ensuring durability under typical operating conditions. The built-in EPDM rubber gasket (RCPL) ensures an airtight connection without the need for additional mounting accessories. As a result, joining pipes with diameters of 125 mm and 100 mm is reduced to simply inserting one element into the other – regardless of the direction of airflow.

• Quick installation: No need to tighten screws or use adhesives shortens on-site work time.
• Universal application: Suitable for mechanical ventilation, air conditioning, heat recovery, and fireplace installations.
• Legal compliance: Possession of the „B" mark facilitates formal acceptance of the installation in accordance with requirements in force since mid-2019.
• Sealing class D: Guarantees appropriate connection quality for standard ventilation circuits.
