The Range Hood Exterior Blower Assembly pulls air through the exhaust vent to remove smoke, steam and other cooking odors from your home. This kit can be installed as an exhaust motor in your ventilation hood or as an in-line blower in the attic for additional noise reduction. The motor measures approx. 15 1/2" (39.4 cm) W x 32 1/2" (82.6 cm) D x 16 1/2" (41.2 cm) H. This complete kit is a universal accessory that can be used in most homes; be sure to confirm compatibility before purchase. Installing this accessory will require complicated disassembly and prior repair experience. Specialized tools may also be needed. We recommend that you hire a qualified technician to install this blower kit. If installing yourself, remember to shut off the necessary house circuit breaker(s) before you begin.
