This 90° transition piece allows the connection from a round Ø 100 mm duct to a rectangular 55 × 110 mm duct.
Made from fire-retardant, self-extinguishing PVC material, suitable for temperatures up to 80 °C.
The smooth inner surface reduces airflow losses and increases efficiency compared to traditional flexible ducts.
With a compact height of only 55 mm, it is ideal for installation in suspended ceilings or tight spaces.
Easy assembly via plug-in connection (male / female).
Robust and resistant to moisture.
Versatile use in ventilation and exhaust systems, roof penetrations, and solar installations.
Ready for shipment within 24 hours after payment.
