The carbon free compressor pump system is a device that utilizes several pistons in a hydraulic or power press manner to compress gas or pump fluids. The device utilizes mechanical advantage of a pulley on the upstroke and uses a clutch device to utilize the gravitational force on the downstroke. In order to accomplish this the device includes a base that allows the compression process to take place and ensure there is only vertical movement. Further, the weight block ensures the system can utilize gravitational force on the downstroke. Further, the plurality of outtakes allows for the gas or fluids to flow out of the system once compressed or pumped. Furthermore, the conical tank takes the compressed gas or pumped fluid and further compresses the gas, increasing the pressure without moving parts. Thus, the device operates on carbon free electricity to compress gas and pump fluids.
