AC Infinity Flexible 10-Inch Aluminum Ducting, 25-Feet Long

This is probably the best non-insulated flex duct available with a foil liner. It does provide some modest insulation but not to a real R value. It is however much less bulky and easier to work with than true insulation rated duct. I used it to connect an Aprilair E130 dehumidifier to my return side HVAC ducting and it was perfect for my needs. I do wish it came in white or gray though. I think that option would be a real selling point for this type of product, rather than black. Also, while this is still the thickest non-insulated flex duct duct I’ve found, they count the metal spring that keeps the duct shape as one of the four layers, which is not a very honest way to market this otherwise best of class product.

top, vorne aus dem lüfter kommt fast keine luft raus, was zeigt dass es hier fast keinen strömungswiderstand gibt. rohre mit größeren abständen bei den ringen hatten hier probleme, da das material eingesackt ist und den rohrdurchmesser starkt reduzierte. passiert hier nicht.

Used this with an E080 dehumidifier. Sliped snugly over the inlet and outlet. It was a little tight on the HVAC pipes but still worked. The included clamps work great, I wish there were 4 instead of 2 but no biggie. The material is plenty thick, and very flexible. I had to snake between two pipes that were about 8in and this conformed nicely.

It is what it says it is. It likes just a little being round enough so close I made it work. They need to watch that part in making it. Because In tight places that would be hard to do. But so far it's great. I used it on my heat and air conditioning. I'm going to redo the duct work for return vent I'm going to order more of this.

I needed some ten-inch vent duct for a crawl space dehumidifier. I’ve had experience with the cheap foil ducting and hate working with it. The foil always rips and the wire pokes out. I decided to spend the extra money to try this product and I’m glad I did. This ducting is covered in some sort of thick plastic so no foil is exposed. Inside there’s a woven metallic fabric. The wire coil stays where it should even when flexing the ducting. Made the job much easier.
