AC Infinity Flexible 8-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 25-Feet Long for Heating Cooling Ventilation and Exhaust

スポットクーラー用の延長ダクトとして使ってます。 末端は写真のように綺麗にカットされていませんが、コストパフォーマンスが良いです

I use this with an AC Infinity Ventilation fan that I have converted into a window fan. This allows me to direct air exactly where I want, to my sleeping area. As a result I sleep like a rock. I've been using this for about 2 years now and it is holding up, although if you accidentally step on it or apply a force to it this might result in bending the coils a bit. So far this has only happened minimally. Ideally if you can set it up once and not move it around it should last near indefinitely. If you move it around and you are careful maybe as much as 5 to 10... that's what the judge said when I asked what time it is... Seriously, it's rugged enough if you handle it with a degree of care. I'm staying quite cool with it. This also works to redirect the air from my AC when it's too hot in NYC to uses a window fan. Enjoy for this reason or for growing to hearts content. Just a reminder, that although the latter part of what I'm addressing is now pretty much legal all over the place. Ultimately this adds an advantage to those that do not imbibe by automatically elevating the non-participant to a level of genius. Recommended.

As a sheet metal journeyman that does not typically like flex, this product is good. It does not fall apart, it is not too thin. I have used a lot of flex and this was by far the best.

This is really good stuff

Needed this for heat,was easy installing
