  • Linsheng,Ltd Automotive Air Compressor, Output Exhaust Pressure Is Too Low: Cause What happens when the exhaust pressure of the air compressor of the car is too low? What is the cause? Linsheng Electrical Company Answer  1. If the actual gas consumption is greater than the gas production of the unit, the connected equipment and pipe network should be inspected, and if there is a leak, repair it in time. If the gas consumption of the system is greater than the air volume of the compressor unit under normal use conditions, the compressor unit of a large size should be replaced or the compressor unit should be added.   2. The unloading pressure setting is too low. Set the unloading pressure value correctly and make full use of efficiency.   3. The air filter element is dirty and blocked, resulting in insufficient intake of the compressor unit and low exhaust pressure. The air filter condition should be checked and replaced if necessary.   4. Solenoid valve failure.
