Wall or ceiling mount, LoProfile is the right fan for a tight fit. The new Broan
LoProfile
Fan is our latest solution 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 2x4 studs.
When plumbing or electrical obstructions are found behind the drywall in
ceiling remodel applications our 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.
