A type of electricity and air supplying equipment, which includes: a clutch mechanism, a belt assembly, a motor having a transmission shaft, a generator unit having a generating wheel, and an air compressor having an air compressing wheel. The clutch mechanism has first and second clutch shafts that can be engaged or disengaged. The belt assembly includes a first belt connected between the transmission shaft and the generating wheel, a second belt connected between the generating wheel and the first clutch shaft, and a third belt connected between the second clutch shaft and the air compressing wheel. The motor drives the generator unit to run and generate electricity, and meanwhile, the generator unit drives the air compressor through the clutch mechanism. Thus, the equipment can use single power for electricity generation and high-pressure air production, while providing heat insulation and easy assembly.
