Abstract
Air compressor in which the arrangement structure between a filter part and a discharge resistor reduces interference between the filter part and the discharge resistor and increases the space utilization of the filter part, making the air compressor more compact. The air compressor comprises a housing with a rotary shaft disposed inside it; a compression part connected to the rotary shaft which compresses and discharges introduced air; a motor part driving the rotary shaft; a control board for controlling the motor part, and the filter part which filters noise of external power and supplies the external power to the control board, wherein the filter part includes a capacitor assembly connected to an external power source, a transistor connected to the control board, a current sensor assembly connected to the transistor, and a discharge resistor connected to the capacitor assembly and discharges the residual charge in the capacitor assembly.
