載の圧縮装置。[Claims for Utility Model Registration] (1) A first and second compressor, a motor for driving each of the compressors, and an air tank to which pressurized air is supplied and stored by each of the compressors. an unloader mechanism that causes the first compressor to stop supplying pressurized air to the air tank; and an unloader mechanism that causes the first compressor to stop supplying pressurized air to the air tank; a detection section that detects that the rotation speed of the engine has fallen below a preset lower limit rotation speed and outputs a rotation speed reduction signal; and an unloader drive means that operates when the rotation speed reduction signal is output from the detection section. and when the power supply voltage of the motor is reduced and the rotational speed of the motor is in the reduced state, the first compressor is kept in an unloaded state and the air tank is applied only by the second compressor. A compression device characterized by supplying and accumulating pressurized air. (2) The compression device according to claim 1, which releases the unloading state of the unloader mechanism when the motor rotation speed exceeds the lower limit rotation speed. (3) The compression device according to claim 1, which releases the unloading state of the unloading mechanism when the power supply voltage supplied to the motor increases to a lower limit voltage or higher.
