VEVOR 25FT PVC Flexible Duct Hosing for 12 INCH Utility Blower Exhaust Fan (12IN 25FT)

So I bought one of the orange exhaust fans Amazon sells it comes with these tubes that was an 8 inch but the 8 inch flex duct that comes with it is too restrictive and it creates back pressure and actually blows out and after doing quite a bit of research and I was buying a 12 inch the calculations are a 10 inch flex duct is the appropriate size for inch fans Because if you go with 12 inch it doesn’t have enough velocity to move say paint or dust through the flex duck and it settles Where as the 8 inch 48 inch is too restrictive decrease back pressure and it actually blows out. If you have a 10 inch fan blower that you wanna 12 inch flex duct

It’s bigger than I thought, waterproof for sure and seems very durable. I use it on my Kitchen exhaust fan and I can wash it when they are as oil.

This thing is amazing! Ran a swamp cooler to a bedroom which was the intended purpose and yes, I know people have mixed opinions about it but my bedroom is an igloo now.

I got the 8 inch duct hose to connect to a dehumidifier in a crawl space encapsulation. I've have found that the area closer to the door access has a slightly higher percentage of humidity. This has helped to balance the humidity by circulating the air.The Duct Hose is high quality commercial grade, thick vinyl, with a heavy solid wire coil spring. The hangers allow you to suspend the duct, or it would roll around the ground and coil up.I had to buy a diy metal clamp strap with worm gear to keep it secured to the short 8 inch collar of the dehumidifier.

worked great and as described I used it to store my mega christmas tree

Pretty durable, fair price

This was perfect for my needs

So far is in great condition is made of good material 👍
