Abstract:
A dual fan blower module of the present invention includes a housing defining a central motor compartment and first and second scroll chambers. The scroll chambers are axially aligned with and located on opposite sides of the motor compartment. A motor is mounted within the motor compartment and has first and second shaft ends extending axially therefrom. The first shaft end extends into the first scroll chamber and the second shaft end extends into the second scroll chamber. A first fan is mounted onto the first shaft end within the first scroll chamber for rotational movement within the first scroll chamber and a second fan is mounted onto the second shaft end within the second scroll chamber for rotational movement within the second scroll chamber. Each of the first and second scroll chambers includes an expansion channel extending axially inward toward the motor.
