The experimental analysis of the wood chip removing system during its redesigning in the existing sliding table circular saw and computational fluid dynamic (CFD) numerical simulations of the air flow process is presented in the paper. The attention was focused on the extraction hood and the bottom shelter of the actual existing system. The main aim was to perform experimental research on the pressure distribution inside the hood and at the exit of the bottom shelter and the air flow distribution during operation of wood chip removal system. In the work a systematic experimental study of pressure and numerical modelling of the air flow distribution in the upper cover and bottom shelter during operation for the selected rotational speed of saw blade of 3 500 and 6 000 min-1 with a diameter of  300 mm and  450 mm were carried out. The analyses of results obtained from the experimental measurements and numerical simulations allowed the estimation of the areas with improper air flow hindering the controlled transport of wood chips and to optimize the shape of extraction hood and the bottom shelter. As the result, a new design of the chip suction system was obtained, noticeably improving the chips extraction from the tool operation space.
