Added a 4" dryer tube and I run the exhaust outside. Perfect for exhausting my coffee roaster and not filling my garage up with smoke. Really quiet so I can easily hear 1st and 2nd crack.
I love these in line fans they work great in my 10x10 tent setup. Being able to plug two fans into one controller is a added bonus. They are energy efficient,extremely quiet, and powerful. Thanks Vevor!
I have been using this fan for about a week now. It is quiet and doing what it is intended for. I can only give a 4 star at this time due too the short time.
I installed this with a thermal switch in an attic to help exhaust hot air. It moves a lot of air for its size. It's not silent but it is quiet enough for my needs. It seems to be well built with heavy duty materials. I will be ordering another one.
This fan is an excellent little fan wit lots of programming flexibility and adjustability. The price point is also unbeatable. You wont find a better fan and control package for the money, for the same CFM.
Great fan! Easy to install and get up and running. I do wish it came with 6” ducting, but understand at the value the fan. It’s quiet, has a sensor for temp and humidity. And flexible in its control settings.
