Very pleased with this product, the fan is well made and powerful considering the price. The seller was also very helpful when I asked questions about the product.

You'll need a cable gland to attach it to the electronics box, and you'll need to make the hole for that a bit bigger than normal because the screw column in the electronics box is in the way of the cable gland nut.this thing seems quite powerful but I'm a bit wary because it needs to be balanced better which is a bit hard since the squirrel cage fan is too lightweight. There's 2 moveable counterweights on the vanes in mine, maybe needs a few more because they don't look heavy enough.the casting of the motor housing is a bit crooked, the chassis arrived a bit bent from being dropped but it was easy enough to bend back.the speed control is great to have, still have no idea how it works given that induction motors are 50/60 hz dependent. but the fine tune control must be turned down to a lower range, otherwise the motor will hum while it's set low.It'll need a power switch.
