Concentric reducer for round ducts by VSP.

The reducer is used to join round ducts of different diameters in supply and exhaust ventilation systems. The symmetrical conical shape keeps the airflow axis centred, ensuring a smooth change of cross-section, stable aerodynamics and minimal pressure loss.

The nipple ends with rubber seals provide quick installation and a highly airtight connection without additional sealants. Galvanised steel protects against corrosion and adds strength.

The concentric reducer is suitable for supply and exhaust ventilation systems in residential, commercial and industrial buildings.
