Broan NuTone 110 CFM Energy Star Bathroom Fan

The fan is designed for installations where conventional ventilation simply won't fit. When a multi-family application requires it, the fan is narrow enough to be installed in a wall between 2 x 4 studs. When plumbing or electrical obstructions are found behind the drywall in ceiling remodel applications. The fan can still fit without having to move anything, and that means most any room with space constraints can have powerful, quiet, efficient ventilation.
