The “Tornado-Flex In Sack” is an air ventilation duct made from single-ply polyester reinforced PVC vinyl fabric, reinforced with a spring steel wire helix designed to provide protection and durability for the hose. The PVC vinyl fabric also offers good resistance to various chemicals and fumes, making this hose appropriate for a wide variety of applications. This hose is generally used to move large volumes of air, smoke, and fumes using portable and temporary ventilation blowers under positive pressure.
The “Tornado-Flex In Sack” has a temperature range of -20 degrees to +180 degrees Fahrenheit, which permits the hose to operate near warm machinery. This air ventilation duct is also manufactured with flame retardant materials and can be used in environments where safety is a concern.
The unique feature of this product is that it includes its own self-storage bag that the industrial hose can be stored into for easy storage and portability. Since this hose has a 10 to 1 compression ratio, compressing and storing the hose after use comes with ease. This portable air transfer hose is perfect for temporary applications that require the movement of large volumes of air, smoke, and fumes. The ability to carry the sack from one job to the next is a big reason why this hose is chosen over other hoses. In addition to the spiral steel wire helix, this air transfer hose features an external wear strip that offers additional external abrasion protection and drag resistance. This is an important feature since this portable industrial hose is expected to experience more external abrasion than other static hoses.
The “Tornado-Flex In Sack” rubber hose is offered in 15 and 25-foot sections, each in yellow with a black wear strip. This rubber hose is cut with one end being an enclosed belted cuff and the other featuring an enclosed nylon ring. Both ends allow for quick and effective connection to other “Tornado-Flex In Sack” hoses of the same size. The ID sizes offered for this product range from 6 to 24 inches with an ID tolerance of -0.00 to +0.375 inches. This industrial hose is also easily compressible, allowing it to fit into its storage bag for quick on-the-go portability. The portability of this air transfer hose makes this great for air, smoke, and fume applications such as air duct cleaning, confined space ventilation, smoke ejectors, humidity control, HVAC, and other general-purpose jobs.
