  • Soffit fan
    Patent number: 6220956
    Abstract: An apparatus for increasing ventilation of heated and/or moisture-laden air from an attic or roof crawl space (12) in a dwelling or the like, a soffit fan (30) acts to accelerate natural convection by creating an air flow (16) from pulling cooler, denser outside air into attic space (12). The cooler air flow (16) displaces the heated and/or moisture-laden attic air; the attic air rises and is expelled through an opening at or near the top of a roof, preferably through a ridge opening (20) in a roof ridge ventilator (18).
