Sandblasting

To sandblast the following specifications of a compressor are important:

     Since in practice a good result is achieved at a pressure of 4-6 bar, the pressure is not the problem.
    A larger storage tank is required to be able to sand sand comfortably. The tank contains our 'stock' of air. The sandblaster takes air from the storage tank after which the compressor has to replenish it. A 25 liter tank is generally too small. The minimum required for, for example, small blasting is at least 50 liters but better 100 liters.
    The effective volume of air delivered (discharge volume) that the compressor can supply (l / min) must be as high as possible, this volume determines the speed at which the storage tank of the compressor can be supplemented.

Manufacturers often only provide the volume of air that is sucked in per minute (intake volume). This number is much higher (25 to 40%) than the effective volume that is delivered efficiently (emission mode).

If the sandblaster uses more air per minute than the compressor can supply, it will be necessary to wait until the compressor has sufficiently replenished the tank for further blasting.
