What is the oil content of the general air compressor

General air compressor oil content standards vary by type and application scenarios:

1. ordinary air compressor: The national standard stipulates that the liquid oil content in compressed air shall not exceed 5 mg/m & sup3;, and the oil vapor content shall not exceed 0.5 mg/m & sup3;. The purpose of this standard is to ensure the basic quality of compressed air and to avoid oil contamination of equipment or products.

2. Micro-oil air compressor: The oil content in the outlet air shall not be higher than 0.01 mg/m & sup3;. This type of equipment is suitable for scenarios that require high oil control, but still allow trace amounts of oil.

3. Oil-free air compressor according to the ISO 8573-1 industry standard, the oil content of compressed air must be less than 0.01 mg/m & sup3;(I. e. CLASS 0 level), can be identified as oil-free compressed air. Granklin water lubricated single screw air compressor through the water film instead of lubricating oil, to achieve zero oil pollution in the compression process, fully meet this stringent standard.

4. Oil-injected screw air compressor: Generally, the oil content of compressed air is not more than 3ppm (that is, the oil content per cubic meter is not more than 3mg). If the oil content exceeds this value, it is regarded as "high fuel consumption" or "flying oil", which needs to be solved by maintenance or replacement of oil and gas separator and other components.

Oil content differences in industry applications:

• food and pharmaceutical industry: The oil content of compressed air should be strictly controlled at 0.01 mg/m & sup3; below to prevent oil from contaminating products and ensure food safety and drug quality.
• Electronic industry: The oil content should be less than 0.1 mg/m & sup3; To avoid damage to precision electronic components caused by oil.
• Chemical Industry: The general standard is not more than 5 mg/m & sup3;, but the specific requirements may be adjusted according to process requirements.

Advantages of Grantklin Water Lubricated Single Screw Air Compressor:

• zero oil pollution through water film lubrication and sealing technology, the pollution of compressed air by oil is completely eliminated, and the highest standards of food, medicine, electronics and other industries are met.
• Low temperature operation: Water cooling effectively controls the compression temperature, prolongs the life of the equipment and reduces the risk of fire.
• Low noise design high frequency compression combined with water film damping technology, operating noise is significantly lower than the traditional air compressor.
• Energy saving and high efficiency: The two-stage compression technology reduces energy consumption and saves about 20% energy compared with the first-stage compression under the same working conditions.
