The system includes a frame configured to be supported on support surface defining a plane. An air storage tank, supported by the frame, has a center of gravity at a first height measured along a direction perpendicular to the plane. A power supply, removably coupled to the frame, has a center of gravity at a second height measured along a direction perpendicular to the plane. A motor, driven by the power supply, has a center of gravity at a third height measured along the direction perpendicular to the plane. An air pump, fluidly coupled to the tank and driven by the motor, has a center of gravity at a fourth height measured along the direction perpendicular to the plane. The first height and the second height may be less than the third height and the fourth height. ## Claims ### Claim 1 An air compressor system comprising: a frame configured to be supported on a support surface, the support surface defining a plane;
