The Aluminum Flex 280 – Compressible is an aluminum duct that extends from 0.8 meters to 3 meters, a ratio of 1 to 3.7! This metal duct has a single-ply, helically corrugated structure—making it a very durable, as well as lightweight product. These helical corrugations are one part of the reason for why this duct can extend to over three times its compressed length!
In addition, because of aluminum’s natural resistance to high temperatures, this aluminum hose can withstand temperatures of up to 284 degrees Fahrenheit! On the low end, it operates efficiently in temperatures of as low as –22 degrees Fahrenheit. In total, the Aluminum Flex 280 – Compressible presents a very wide temperature range. And, considering its price-point, this hose is one of the most cost-effective high-temperature ducts within our collection!
The Aluminum Flex 280 – Compressible comes prefabricated in a variety of different inside diameter (I.D.) sizes: 3″, 4″, 5″, 6″, 8″, 10″, and 12″. The walls of this flexible metal tubing are 0.1 to 0.11 mm. thick, and it has an I.D. tolerance of 0 to 0.1 inch. Its end finishes are plain cut, and it comes in a classic, metallic-silver colorway. This flexible metal hose is also semi-rigid, which means that, once you bend it into a certain position, it will stay that way without any added support. Of course, you can bend it again to reform the duct into a different position. In sum, it’s likely that you will not need to use any accessories such as elbows to fit your Aluminum Flex 280 – Compressible into looping or bent positions.
This flexible metal duct is designed with air and fume ventilation applications in mind, thus making it well-suited for a variety of residential, commercial, and industrial applications—especially those that intend to transport high-temperature matter. Wood stoves, for instance, need to properly ventilate hot smoke from the wood they burn. The Aluminum Flex 280 – Compressible is a natural fit for these kinds of applications—especially since, oftentimes, a wood stove’s exhaust duct must navigate a circuitous pathway to reach the destination where it expels the stove’s fumes. Other common uses for this metal flex-duct include chemical fume ventilation, circuit board cooling, and air conditioner ducting, among other things.
