Broan LP80 Bathroom Fan 80 CFM

Designed for installations where conventional ventilation simply won't fit. Where multi-family applications require it the LoProfileT fan is narrow enough to be installed in a wall between 2x4 studs. When plumbing or electrical obstructions are found behind the drywall in ceiling remodel applications the LoProfileT fan can still fit without having to move anything. And that means most any room with space constraints can have powerful quiet efficient ventilation.Top to Bottom: 4 Overall Width. Side to Side: 14 Overall Depth. Front to Back: 14 Duct Diameter: Round: 6 Housing Width. Side to Side: 11.
