Abstract

PURPOSE:To obtain a fan having small pressure loss due to a filter and lesser working noise by rotating the filter and blades in the same direction. CONSTITUTION:A circular filter 7 is fixed to the axle of an electric motor 2 with setscrews 3a together with blades 3 on the suction side. As the motor 2 works, the blades 3 and the filter 7 rotate in the same direction and at the same speed. At this time air current is produced in the ventilation flue 4a enclosed by a window channel 4 but working noise gets quiet as the current flows smoothly between the filter 7 and the blades 3. Attachments on the filter 7 such as fats and oils or dusts, etc. are collected on the external circumference of the filter 7 on account of centrifugal force due to revolution of the filter 7 or flied away beyond the filter 7. Accordingly, the air permeability of the filter 7 does not increase so much, times of cleaning required are reduced and, in addition, the conventional supporting frames can be omitted.
