High Quality, Value Priced Ducting Fits All Portable Ventilation Fans. 8 in. x 25 ft. long. Strap and clamp adjustment. Sporting a full 25 ft. tube of two-ply polyvinyl with polyester reinforcement, you get one rugged length of ducting. All of which is kept open and clear for constant airflow by a reinforced helical wire along the whole length of the duct. And with a temperature range of -20 to 180 degrees F the EckoFlex is fire retardant, so you can be sure your duct will perform well wherever you need forced ventilation or atmosphere extraction; be it ship breakers, sewer entry, engineering, refineries, oil rig work or even as an engineer needing to do a spot of manhole entry. Each length of duct includes a storage solution. Check out the sturdy nylon duct sack from Euramco, a great hardy bag featuring shoulder straps for ease of transport.
