Publication number: 20230327524Abstract: The present invention relates to an air compressor which improves the space utilization of a filter unit, and reduces the number of constituent parts constituting the filter unit, thereby improving assemblability, reducing manufacturing costs, and minimizing the size of the air compressor itself. The air compressor comprises: a housing; a rotating shaft extending in the longitudinal direction inside the housing; a compression unit disposed in front of the rotating shaft and rotated by the rotating shaft to compress and discharge air that flows in; a motor unit which rotates the rotating shaft; a control board which controls the motor unit; a filter unit which supplies external electrical power to the control board and filters the noise of the electrical power; and a bus bar assembly which transfers the electrical power from the control board to the motor unit.Type: ApplicationFiled: September 8, 2021Publication date: October 12, 2023Inventors: Kyu Sung CHOI, Hyun Chil KIM, Gun Woong PARK, Min Gyu PARK, Chi Yong PARK, Yeol Woo SUNG, Hyun Sup YANG, Jong Sung LEE
