The ECKO-FLEX 12 in. x 5 m Flexible Ducting is high quality, value priced ducting that fits all 12 inch portable ventilation fans. It features a strap and clamp adjustment and measures 12 in. x 5 meters long. If you need your ventilation fan (like the ECKO K30 12 in. Blower) off-site but still need focused ventilation or air extraction, then this length of flexible ducting is what you need. Reinforced with polyester, the two-ply polyvinyl construction is incredibly strong. It features a helical wire running the length of the tube, keeping it wide open and ensuring maximum airflow, even over a distance (5 meters). The ECKO-FLEX Ducting operates over a vast temperature range (-20 to 180 degrees F) and is flame retardant. Wherever you might need forced ventilation or extraction of gases, the ECKO-FLEX Ducting is the perfect tool. Included with each length of duct is a storage solution for your ECKO-FLEX, a Euramco 12 in. nylon duct bag, which features shoulder straps for ease of transport.
