Title: Air deflectors to accommodate multiple size ventilator outlets

Abstract: A pair of air deflectors attached to the outlet opening of a blower assembly housed within a ventilator housing to accommodate multiple size outlets in the ventilator housing of a ventilation system. The air deflectors include a front portion for attachment to a sidewall flange extending outwardly from the outlet opening of the blower assembly, a transition portion extending rearwardly and inwardly from one side of the front portion, and a flange extending rearwardly from the transition portion for attachment to a sidewall of the blower assembly. The air deflectors attached to the outlet opening of the blower assembly increase air flow, decrease air turbulence and decrease noise within the ventilation system.
