For inspection machines used in checking intricate devices, the environment inside the machine should be usually maintained with care in order to avoid possible contamination. In this study, internal flow analysis for an inspection machine is done subject to air flowing from the top using steady state condition. From the numerical results, the maximum velocity is found to be 0.97m/s in the vicinity of exits. The average pressure over the workpiece is calculated as 101,317㎩ within 1㎩ difference and the net force on the workpiece found to be 34.6N. Also, it is found that there is almost no swirling flow in front of the workpiece.
