The BlauFast air ducts are made of high-quality plastic using the co-extrusion technology.
The corrugated external layer of the air ducts provides high strength and flexibility. This construction also enables easy bending anywhere without any extra tools.
The sealing ring is used for extra airtight connection of C class of the air duct and the spigot. The sealing ring must be slipped over the air duct. The lock ring ensures reliable fixation of the air duct.
Besides, the BlauFast air ducts are featured with smooth inner surface to decrease air resistance and boost ventilation performance.
