How to choose the right air compressor for the sandblasting machine?

Sandblasting machine from the efficiency and strength of sandblasting can be divided into general pressure sandblasting machine, pressure sandblasting machine, high pressure sandblasting machine. The air compressor connected with the sand blasting machine is generally selected with a pressure of 0.8Mpa, and then the appropriate air compressor is selected according to the size of the air source required by the sand blasting machine. Compared with the other two forms of sandblasting machine, the efficiency of single gun sandblasting is lower than the pressure and high pressure sandblasting machine, and the air compressor required for each gun of this type of sandblasting machine is at least 1 cubic meter per minute, that is, at least 7.5KW air compressor. Both the pressure sandblasting machine and the high pressure sandblasting machine belong to the pressure feed sandblasting machine. The sandblasting efficiency of the single gun is lower than that of the high pressure sandblasting machine. The air compressor required to be equipped with each gun of the pressure sandblasting machine is at least 2 cubic meters per minute, that is, the air compressor required to be equipped with each gun of the high pressure sandblasting machine is at least 3 cubic meters per minute. That is, a 22KW air compressor. In general, the bigger the air compressor, the better.
