AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

除湿機ほ排熱用ホースの為購入。 size 100Φ 、ちょっと大きめでも接続できた。中々 100Φで長さ6mを越えるものがなく、良い商品に巡り逢いました。 ホースの構造もしっかりしていて、かなり伸ばせて使用できるため重宝しています。

Todo bien, gracias

Lo utilizo para sacar aire por medio de un extractor, me parece que tiene una excelente longitud para su precio, excelente!

First thing first, the build is solid, and it seems to insulate well. It fit great and can in some really cool packaging. HOWEVER, I am returning this because the ends of the tube don’t have a clear space for putting in the ring tighteners. The ends are simply just cut, which means you have the spiral wiring going all the way to the end, which your ring tightener will have to go over, thus not a proper seal. If you are a stickler for having flawless insulation on the ends, I would probably get something else.

The construction of this product is very good quality. I bought the 6-inch version of the same product over 5 years ago and it's still in great shape and will last many more years. With this product, there are no light leaks or 'pinholes', like some of the cheaper 'black' ducts that i've purchased in the past. The matte black finish of the outer layer also has a nice aesthetic look to it. Slightly more expensive than some of it's competitors but in my opinion, worth the extra money if you're looking for a quality black duct that doesn't let light through.
