Automatic Compressor

AUTOMATIC COMPRESSOR: this type of compressor uses a reservoir (or tank) . When the reservoir is filled to a certain, preset pressure, (the compressor) shuts itself off automatically. When pressure drops below the preset level during use, resumes filling the reservoir. Auto Shut-off usually means compressor turns off with the airbrush or when air tank is full. Available in many sizes, from small enough for an airbrush to big enough to drive a number of jackhammers.
