Air compressor is the basic product of industrial modernization and core equipment for providing air source power and air-operated system. It is a device that converts mechanical energy (usually electromotor) into gas pressure. When air compressor is at work, air absorbed by self-cleaning air filter, through PLC automatic self-cleaning strainer, enters into first-stage compression, then goes to intercooler for cooling due to the high heat after compression,(water moves inside tube, air flows outside tube, water volume requirement is110m/h) then goes to second compression system, to avoid the air pouring into compression chamber (avoid start with pressure), with a hanging check valve in exhaust pipe, exhaust gas pushes away check valve to enter into exhaust silencer, then goes to first aftercooler, second aftercooler, then goes to main exhaust pipe.

Here is the solution for air compressor HT-250（HB196-241）technique process.
