Designed for installations where conventional ventilation simply won't fit. Where multi-family applications require 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.
