    摘要： Described is a method, apparatus, and system for controlling the exhaust of a vacuum device including at least two conduits capable of routing air within the vacuum device, at least two baffles, at least two air chambers, and at least two exhaust cavities. The baffles and the air chambers are capable of reducing the turbulence of the routed air. The exhaust cavities are capable of discharging the routed air from the vacuum device as two or more converging air streams thus minimizing any adverse effects on the environment or the operator. The system can further include a diffuser capable of increasing the turbulence of the routed air after the vacuum device discharges the routed air to improve the thermal dissipation of the discharged routed air. The system can further include a mounting device capable of coupling the vacuum device to a vacuum operator for increased portability.
