Hon&Guan 5 inch Air Duct - 16 FT Long, Black Flexible Ducting HVAC Ventilation Air Hose for Grow Tents, Dryer Rooms,Kitchen

Not worth for the money No heat resistance between the layer. So chance to heat the outer layer and smell the plastic

I installed a RV furnace in an off grid cabin, and bout these for the ducts. These are, by far, much more heavy duty than the cheap foil ducts used the the RV industry. And they were far less expensive.

I use this insulated flexible hose to heat my rooftop tent from a diesel heater, and it works really well. It is long enough to reach comfortably and the insulation helps keep the heat where it needs to be. The material feels durable and flexible, and the included duct clamps make installation easy and secure. It has held up well through regular use and exposure to outdoor conditions. A solid, reliable product that does exactly what it is supposed to do.

I used it to make giant worms for a Beetlejuice display. It worked great for that. I had it tied up in trees with fishing wire. It was cheaper than any where else I looked and I liked that it was white because I only had to paint the black stripes! My guess is it would also be good for Air conditioners!

Si, se lo puse a un extractor de aire y veo que si funciona
