Focused on compressed air system design, air treatment, piping configuration, equipment maintenance, and common industrial air issues, with practical guidance based on pressure, flow, dew point, air quality, and operating conditions for equipment selection, system optimization, and routine operation and maintenance.
Shanghai Granklin Group Co., Ltd. is a modern enterprise specializing in the design and manufacture of air compressors. Its main products include water-lubricated air compressors, oil-free air compressors, variable frequency air compressors, etc. As a well-known brand in the air compressor industry, Shanghai Grank
Choosing an air compressor with and without oil has its advantages and disadvantages, depending on the application scenario and needs. Oil-based air compressors use oil to lubricate and cool the moving parts inside the compressor, providing a long service life and high work efficiency, and the price is usually
Oil-free screw air compressor is not really oil-free, but its oil content is very low, can reach 0.01ppm or less. This air compressor uses special coatings or materials to reduce or eliminate the parts that need lubricating oil, so that oil pollution is not generated during the compression process
The start-stop sequence of the air compressor and dryer is as follows: start-up sequence: the air compressor should be opened first, and then the dryer should be opened. This is because the dryer needs a stable supply of compressed air to work, and the air compressor is the equipment that provides this supply. In addition, empty
The screw air compressor can be frequency conversion or power frequency, depending on the user's needs and choices. Variable frequency screw air compressor by adjusting the frequency of power supply to the motor, so that the air compressor can run at different speeds, so that the output and compression air
PPM is the abbreviation of the English part per million, which means the number of parts per million or parts per million. It is usually used to express the content of trace substances in the mixture, with weight ratio (PPMw) and volume ratio (PPMv). In the field of air compressor, mentioned
The maintenance of oil-free air compressors mainly includes the following aspects: Regular replacement of the filter element: The filter element is an important component of the air compressor and is used to filter impurities and pollutants in the air. In order to maintain the quality of the compressed gas and protect the internal parts of the compressor, it is necessary
Oil-free air compressor and oil-free air compressor: which is better? In the air compressor market, oil-free air compressor and oil-free air compressor are two common types. They have their own characteristics and are suitable for different application scenarios. So, what kind of air compressor is better? This needs root
There are two main ways to adjust the pressure of the air compressor, which correspond to two different pressure control methods of the air compressor: for the spring-repositionable air compressor, there is usually a rotatable valve at the top. Turn this valve up to increase the pressure and turn it down.
Domestic oil-free air compressor selection guide In industrial production, oil-free air compressors are more and more favored by users with their unique advantages, such as providing pure compressed air, reducing environmental pollution and maintenance costs. In many brands, how to choose a
