Which device compresses air?

Explanation:
In a pneumatic system, the device that increases air pressure is the compressor. It draws in ambient air and compresses it to a higher pressure, supplying the system or a storage tank with pressurized air. The other components have different roles: a regulator reduces pressure to a safe, usable level; a solenoid valve controls the flow and direction of the air but doesn’t create compression; a cylinder uses the energy of already-compressed air to move a piston and perform work. So the one that actually compresses air is the compressor.
