Extendo-Duct
Available in sizes 1-1/2′′ through 12′′ ID in standard 20′ lengths. Highly flexible and permits full airflow, even w/ 90 degree bends. Wire-reinforced polypropylene construction allows hose to maintain its shape. Joining two pieces of Extendo-Duct is easy. Just twist the end of one hose into the end of another. No fittings, menders, or couplings needed. Inert polypropylene material produces no off-gassing and is resistant to a wide variety of chemical fumes, making Extendo-Duct ideal for clean room and chemical fume exhaust applications. Extendo-Duct is suitable for use in temperatures ranging from -4 degrees F to 175 degrees F. Applications Include: Ducting for air-conditioning, spot cooling and heating systems. Room air exhaust conveying and ventilation. Dust collection. Fume Removal. OEM equipment applications.
