Symmetrical galvanized reducer 250/200 with gasket RSOCU250200

Symmetrical Reducer for Ventilation Systems

Galvanized reducer with EPDM seal (RCPL) connects ducts with diameters of 250 mm and 200 mm, enabling smooth transitions between different types of ventilation ducts — such as THERMOFLEX, SONODUCT, SPIRO, FLEX, or ALUFLEX. This component is essential during the modernization or installation of mechanical ventilation and heat recovery systems where a change in duct diameter is required without compromising airtightness.

The EPDM rubber seal ensures airtightness at class D, meeting regulatory requirements for ventilation installations after June 30, 2019 — confirmed by the "B" mark on the product. This is not an optional feature; it is a mandatory condition for legal approval for use in new installations.

Galvanized steel is suitable for environments with moderate humidity, typical of ventilation ducts. It does not require additional corrosion protection under conditions common in residential and commercial construction. Installation is simple — the reducer fits directly onto duct ends without the need for additional clamps or seals.

There is no need to search for separate adapters or converters. This single reducer replaces multiple solutions — it works both during the installation of new systems and when replacing components in existing installations.
