ABSTRACT:
A film handling apparatus blower system. The system includes a blower having a high-pressure, low-volume section and low-pressure, high-volume section. The high-pressure, low-volume section is a scroll-type centrifugal blower with a circular impeller of cellular material to minimize discernible noise, an axial intake port, and a high-pressure outlet port. The high-pressure outlet port is coupled to a duct which directs the output high-pressure air flow into a film cassette. The low-pressure, high volume section is also a scroll-type centrifugal blower having a bladed fan wheel, an axial intake port, and three low-pressure outlet ports. One low-pressure outlet port is coupled to a duct which directs output air flow to a location for flow adjacent the rearward portion of a projection lamp. A second low-pressure outlet port is coupled to a duct which directs output air flow to a location for flow adjacent the frontal portion of the projection lamp. A third low-pressure outlet port is coupled to a duct which directs output air flow across the AC drive motor of the film handling apparatus.
