The invention relates to an air compressor. The air compressor comprises a machine shell, a female screw and a male screw, wherein the female screw and the male screw are arranged in the machine shelland mutually engaged. Tooth shapes of the female screw and the male screw are both asymmetric arcs. According to the air compressor, by means of design and theoretical calculation, the external diameter and the length of a rotor are increased, a newly-designed line type is adopted for the rotor, and therefore the air compressor is good in sealing performance, low in power consumption ad high in efficiency. 本发明涉及种空气压缩机，包括机壳、设于机壳内且相互啮合的阴螺杆和阳螺杆，阴螺杆和阳螺杆的齿形均为非对称圆弧形。本发明的空气压缩机通过设计及理论演算，加大了转子的外径和长度，转子采用了新设计的线型，从而使其密封性好、功耗低、效率高。
