1. Discharge volume

　　Displacement At the rated discharge pressure, The volume of gas discharged by the air compressor per unit time is converted to the volume of gas, which is the air compressor's discharge volume (that is, volumetric flow), the unit is m3 / min. Commonly known, the discharge volume of air compressor which means to how many cubic meters of air per minute the machine inlet, not how much cubic compressed air can be discharged from the machine's discharge port every minute.

　　2. Discharge pressure

　　The discharge pressure of the air compressor refers to the gas pressure (gauge pressure) finally discharged from the compressor, and the unit is Mpa. The air compressor industry commonly uses "kg" as the pressure unit, 1 kg = 0.1Mpa. The discharge pressure marked on the nameplate of the air compressor is called the rated discharge pressure, which is also the maximum discharge gauge pressure allowed by the compressor. Exhaust volume and discharge pressure are two very important parameters of an air compressor.

　　3. Temperature of discharge air

　　The air compressor discharge temperature refers to the temperature of the air discharged from the air outlet of the air compressor airend, The unit is ℃ or ℉. The compressor discharge temperature is an important indicator of compressor safety. Due to the nature of the compressed gas, the lubricating oil, the temperature resistance of the sealing material, the rotor running clearance and other factors, the exhaust temperature is limited, and the exhaust temperature is an important performance parameter of the air compressor unit.

　　4. Air compressor input power

　　Air compressor input power refers to the total input power of the air compressor unit (measured from the three-phase input), the unit is KW.
