Abstract
A draft inducer having a pair of arcuate semi-scrolls within a cylindrical housing defined by a circular inner end plate and a circular outer end plate vertically spaced by a sidewall. A metal conduit element is connected concentrically to the inner end plate and an electric motor is connected adjacent the outer end plate. A fan blower wheel is disposed in the housing coaxially with the conduit element and is drivingly connected to the motor. The semi-scrolls define curved air passages with twin, oppositely directed outlets for discharging fluid flow outdoors at rates minimally effected by ambient wind conditions.
