The LP80 LoProfile fan is designed for installations where conventional ventilation simply won't fit. When a multi-family application requires it, the LoProfile 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 LoProfile fan can still fit without having to move anything, and that means most any room with space constraints can have powerful, quiet, efficient ventilation.
