Often overlooked on our entry level compressors are the various shutdown options available, such as pressure, Dial-a-Pressure, temperature, flow and oil level switches. Our most popular option is Dial-a-Pressure that shuts down the compressor at a given set pressure. This type of pressure switch prevents the compressor from running at maximum pressure for extended periods if the operator is not available to turn off the compressor when the tank is full. The basic pressure switch is factory set by us and is designed to be left at the factory setting. We make an adjustable pressure switch standard on our more feature-rich compressor packages.
