Mastering some basic general data about air compressor operation is very helpful for maintaining equipment and summarizing rules for better use of air compressors.

★ The outlet temperature of the air compressor head is below 95°C for air-cooled machines and below 90°C for water-cooled machines. If it exceeds 110°C, a high-temperature trip will occur.

★ The ambient temperature for air compressor operation is 0-40°C. Too high a temperature will cause the main unit temperature to be too high, while too low a temperature will make it difficult to start the air compressor.

★ The vibration value of the air compressor head is: The main unit vibration value of the air compressor should be less than 7.5mm/s.

2. Air Compressor Three-Filter Operating Data:

★ After oil separation, the exhaust oil content is approximately 1-5 ppm. The typical oil content in compressed air is 3 ppm.

★ The control panel displays: If the air filter differential pressure drops below -0.05 bar, the filter element must be replaced.

★ Air filter filtration: 98% for 1 micron, 99.5% for 2 micron, and 99.9% for 3 micron.

★ Oil filter filtration: 10 μm particle size; the oil filter has a filtration accuracy of up to 0.1 micron. ★ The typical differential pressure of a new oil filter is approximately 0.2 bar. The maximum differential pressure of the oil-gas separator should not exceed 0.8 bar; any excess pressure must be replaced immediately.

★ Oil filter: Initial differential pressure ≤ 0.2 MPa, maximum operating temperature 120°C. Oil filter: Maximum operating temperature less than 120°C, maximum operating pressure 1.4-2.5 MPa.

Air filter: Operating temperature less than 120°C, maximum operating pressure 1.4-1.5 MPa.

3. Other commonly used data： 

★ The temperature difference between the cooling water input and output is about 15 degrees. Too large or too small indicates that there is a problem with the cooling system. And the cooling water flow rate is more than 3.7 liters/second;

★ A. The formula for calculating the gas output of an air compressor is: 1 cubic meter of gas per 6KW; 1 kilowatt gas output is 0.1633 m3. B. (1) British horsepower (HP) (HP) = 0.746KW = 746W;

(2) Metric horsepower (HP) (HP) = 0.735KW = 735W (this unit is usually used for conversion);

★ Air compressor power conversion table: cubic * 6.6;

★ Air compressor oil: The flash point temperature is 200℃ and the freezing point is -20℃.
