CoxTrek ventilation roof duct ø250

The CoxTrek® ventilation roof ducts are specifically designed for mechanical ventilation applications, both for supply and exhaust air. They ensure efficient airflow and reliable air extraction, even in low winds. Thanks to its advanced aerodynamic design, the CoxTrek® roof duct creates a positive draft in the ventilation duct, resulting in low internal resistance and preventing air backdraft in the ducts. The sophisticated design also allows for effective condensation drainage through three drainage holes above the roof surface – without the risk of leakage into the underlay.
