How to select the right compressors:

1.Air consumption:we shall consider the air consumption reasonably because it will be shared by pipeline leakage, the air dryer consumption, sand blasting machine dust remover back blowing and other equipment. If the air volume is larger, the investment in equipment and power will be increased. If the air volume is smaller, the pressure will not reach the rated pressure, and the sandblasting machine and other equipment cannot be used normally. Generally, a margin of 10% shall be reserved.
2.Working pressure:firstly we shall find the working pressure of all equipment, select the maximum air pressure requirement for air compressor. The higher the pressure, the greater the power consumption. If the equipment requires a large pressure difference, it is better to choose different air compressors to reduce the cost.
3.Reasonable air compressor quality and oil content requirements:different precision oil removal filter combinations can be selected to meet the requirements. Requirements for water content: refrigerant air dryer can be selected to dry the compressed air. Requirements for dust content: different dust removal and filter combinations can be selected according to the site environment to meet the requirements. Based on the principle of sufficiency, do not blindly improve the quality to increase the purchase cost of equipment.
4.Selection of air compressor type:
Piston compressor:complex structure, many consumable parts, heavy maintenance work, general reliability, large size, large vibration and noise.
Screw air compressor:strong reliability, convenient operation and maintenance, good power balance, small noise and vibration, large exhaust volume, small size, saving floor space, longer service life, which is strongly recommended to sandblasting machine.
5.Following is the instructions for choosing the air delivery and working pressure of screw compressor for sand blasting machine, or if you have any problem for selecting the model, please feel free to contact Kotech Compressor team:
