Abstract
A whole house ventilator which can be installed without framing and cutting joists. Struts below the fan blade serve as a support for a fan motor and for a venturi. Adjustable pre-cut sleeving fits over the joists and around the fan to eliminate framing. A shutter assembly may be surface-mounted to the ceiling below the joists.
