Fan 115 VAC 4-5/8" x 1-1/2" Sleeve Bearing

I ordered 8 of these low coast fans to make dust collectors for my shop. When I opend the box I found 2 fans damaged ( which were replaced ) and when hooking up found 2 not to work . These I havent received yet. The dust collectors are working great though....

Of course, it's noisy, (I've heard worse) I figured it would be when you can move this much air. The best cooling fan for the money. I quieted it by using rubber grommets and nylon screws.

Bought units to cool entertainment center.
Much too Noisy for application.
Too noisy even when slowed to an idle.
You get what you pay for.
