Title: shop exhaust fan
Review: Fan works great and has an acceptable noise level, almost queit. The discharge dampers do not close tightly, they fall shut when the fan is switched off. A gusty breeze will cause them to flap open and shut. Next winter I will have to construct a way to seal off the dampers. I would prefer that the dampers close securely or they are provided with a way to dog them shut.
