Compressor
The simple fact: ‘more energy = more production’ certainly also applies to compressed air blasting. The compressor must therefore match the type of blasting and the size of the project.
In fact, with more compressed air capacity, larger nozzles can be used that give a larger blast pattern. This enables faster work. Depending on the specific company or project situation, you can choose a stationary electric compressor or a mobile, often diesel-powered, model.
Dry & clean compressed air
To prevent abrasive clogging, ensure a constant abrasive flow and guarantee a better surface result (ready for further processing), dry and clean compressed air is indispensable. In mobile compressors, this air quality is achieved using a (built-in) compressed air aftercooler and filters. In a stationary setup, this is further improved with a refrigeration dryer, which is usually supplied by the supplier of the complete compressor solution.
Compressed air consumption
The compressed air consumption of a pressure blast system is largely determined by two factors:
- the nozzle orifice diameter
- the set blasting pressure.
Machine type or size have no influence. However, the compressed air consumption of the nozzle must be combined with the consumption of any additional components to select the appropriate compressor capacity.
You can download our table showing compressed air consumption in m³/min and cfm for different nozzle diameters and blasting pressures. Using our calculation sheet, all diameters and blasting pressures can be calculated by yourself.
