The Air King EWF-180 Through-the-Wall Exhaust Bath Fan is a 180-CFM exhaust fan that mounts directly through an exterior wall instead of through the ceiling — purpose-built for bathrooms and utility rooms above unfinished basements, in slab-on-grade construction, or in additions where ceiling-mount ducting isn’t practical.
The 180-CFM rating handles a master bathroom or large laundry room sized space and the 6.5-sones rating is acceptable for utility-room ventilation where bathroom-fan quietness isn’t the priority. The white finish blends with standard wall plates, the unit ships with a back draft damper that prevents outdoor air from blowing back in when the fan is off, and the corded electric layout simplifies retrofit installations.
Air King manufactures ventilation fans in West Chester, Pennsylvania — the EWF-180 carries Made in USA designation per the manufacturer’s listing. Pair this through-wall exhaust unit with the Air King AS120 ceiling-mount Advantage fan when a multi-bath house needs both wall-mount and ceiling-mount exhaust units sized to each room.
