An aeration/ventilation device to be mounted on an aperture of a soffit may include a mounting platform to cooperate with the aperture of the soffit, a motor housing connected to the mounting platform, and a fan motor connected to the motor housing to a.) pull/draw cooler air in from the exterior of the soffit (under-eave) area of the building structure thus forcing the cooler air into the soffit interior and on into the attic space. b.) pull/draw hotter air out from the attic space into the interior of the soffit area thus forcing the hotter air out from the under-eave area of the structure. The aeration/ventilation device my use a double, single or multiple fan motors. These fan motors may be fixed to or be adjustable to the pitch angle of the roof structures. The aeration device my also include an electronic control housing to control the operation of the fan motors. The exhaust side of the motors may be fitted with adjustable air thruster device to create the effective exhaust velocity for improved air ventilation and circulation, along with a domed intake screens designed for improved air intake velocity. As well as being equipped with an intake rain guard(s).
