A baffle between the blower and the heat exchanger of a ventilation system evenly distributes air flow over the heat exchanger surface which air flow otherwise would be concentrated along one wall of the system housing and through a localized portion of the heat exchanger. The baffle has a flat panel mounted on the wall adjacent the concentrated air flow and has spaced curved vanes extending into the air stream to direct portions of the stream away from the wall. Diffusers between and downstream of the vanes spread out air currents which pass between the vanes.
