A blower for a furnace is provided with an inlet guide to increase efficiency and pressure output of the blower. The blower includes a blower housing with an inlet opening and an outlet discharge opening. A cylindrical wall is provided around the inlet opening and projects into a hollow interior of the blower housing. A radial wall extends outward form the cylindrical wall toward the discharge outlet opening to prevent recirculation of gases from the outlet to the inlet during operation of the blower.
