Questions & Answers

How loud does it have to be to be considered decibel?

At 1m to the side, the lowest setting is 41dBA and the highest setting is 57dBA. I do not know the manufacturer's specifications, but at the lowest setting, the volume is 41dBA and at the highest setting, it is 57dBA.

What is the status of the speed controller?

You do indeed need to plug the cord into an electrical outlet and the inline dial speed controller is part of it (as you can see in the Amazon photo). This device does not require any wiring.

This can be nailed to the wall, right?

You might be able to mount the unit if you purchase a bracket. However, this might not be the case straight out of

It is not round in the intake
3/5

There is an oval shape to it. As a mounting device for this fan, I've used a hard plastic 4 inch flange. The intake part of the iPower 4 inch inline fan is round, but the fan crossbar is too wide, and the intake part of the fan has an oval shape that does not fit If the flange were more flexible, I am not sure it would even work without cutting and sealing up the opening with duct tape (if it was aluminum). The error can either be caused by a production error or a basic engineering Those who return the unit will be reimbursed.

The fan is perfect for your wood stove
5/5

With this fan, as well as some aluminum piping, I made a windmill. During the winter, I have an old fireplace that I use for my wood stove. Until a few months ago, I used this to move hot air around and over cast iron stoves, then out into a I really like it. I am very happy with the.

An air vent is broken
3/5

broke, it relied on adhesive to hold the blade to its rotating rod, and when it got too hot, it snapped. As a result I am returning it and would highly recommend looking for something else. I had it for 8 days and it gave out in 90 degrees F.

A good distribution fan at an affordable price
5/5

It's been running for a month or so now and so far there have been no issues. This item is simple to install but the speed-control seems to be useless since it does not appear to.

I like the way this little fan works
5/5

I like this little fan a lot. * Made of a durable material. There's a fair amount of quiet. There is a lot of noise coming from them.

This is a great option because of the adjustability
5/5

I find that this little fan is ideal for the purpose I have in mind. There is an option for less air flow noise at low speeds or more air flow noise at high speeds.

I was able to fit a 6in vent pipe outlet perfectly
5/5

The quality and the speed control rheostat make this a great investment.

I don't know
3/5

It would have been better to choose a stronger fan than this one, it's just not powerful.
