Aluminium and PVC Compound flexible air ducts are specifically produced for discharging welding fumes and dense chemical gases where high mechanical resistance is required. Combi-alu/pvc is produced from multi layer aluminium strengthened with high tension steel spring wire, covered with a nonflammable PVC jacket. Combi-alu/pvc flexible air ducts are also recommended for heating, cooling and air-conditioning systems. An important aspect of Combi-alu/pvc is its non-condensing property. Combi-alu/pvc flexible air ducts are elastic and flexible. They can be easily fitted to circular, oval or rectangular connectors.
