Abstract

PURPOSE:To prevent the amount of ventilation from decreasing by a method wherein the filter in front of the suction hole of a ventilating fan frame body is replaced automatically by fresh filter in synchronization with the operation of the ventilating fan. CONSTITUTION:When an electric power source switch 10 is shut, a motor 2 for driving a fan 3 and a motor 13 for driving the shaft 12 of the 2nd storing part are driven, the air is absorbed for ventilation in the direction of the arrow B and simultaneously a filter 9 is wound on the shaft 12 and advances. Accordingly, the filter 9 in front of the suction hole is changed sequentially to fresh filter 9, renewed always, hard to be jammed up as compared to the static filter, oil dust collecting effect is fixed and the quantity of ventilation can be prevented from decreasing.
