The component in question is a device that regulates the operational pressure of an air compressor. Specifically, it is calibrated to interrupt the electrical supply to the compressor motor when the internal pressure reaches 150 pounds per square inch (psi). This prevents over-pressurization of the tank. For example, once the air tank of a compressor reaches 150 psi, this component halts the motor, conserving energy and preventing potential damage.
This device is crucial for ensuring safe and efficient operation of compressed air systems. By maintaining pressure within defined limits, it safeguards equipment from exceeding its maximum pressure rating, thereby preventing failures and potential hazards. Early pneumatic systems often relied on manual regulation, whereas modern systems utilize such automated devices to enhance reliability and reduce the need for constant monitoring.
