Abstract
A vacuum is provided with multiple exhaust points which provide for quieter, lower velocity discharge of the air from the vacuum source. The multiple exhaust points are supplied from a radially extending chamber that is defined between upper and lower panels. The radially extending chamber has both vertical and radial sections that operate to slow the velocity of the exhaust air to reduce the noise generated by the vacuum.
