Matching a Compressor To Your Wetblaster
In order to get the most from the Dana-Ridge wetblast system, it is a good idea to have a compressor that allows the full capabilities of the wetblast unit to be realised. This is true for all dry and wet blasters alike.
Too small a compressor and you will find that the processing times may increase and/or the operational lifetime of your compressor may be reduced as it works harder to keep up with the air demands. Air volume required is less when blasting at lower pressures hence the ranges given.
The volume of available air (CFM/LPM)* is as important as the pressure (Psi/Bar). With these machines there’s no need to exceed 6.2bar (90psi). It won’t harm the machine at all but it will cause increased media usage, reducing the processing advantages.
The air-jets are large enough to allow atomization of the slurry and so the free air delivery is important.
*(CFM= Cubic Feet per Minute, LPM = Litres Per Minute)
There are a few options when it comes to compressed air :-
- Large single-phase compressor (for Mercury or modified Comet)
- Two single-phase compressors joined together (for Comet or Mars)
- Large 3-phase compressor ~7.5 kW (10 hp) or greater (all machines)
- Standard 3-phase to the premises. Mains -powered
- Diesel powered compressor or generator
- Phase converter. Allows 3-phase compressors and machines to be run from single -phase 240V power.
Note: The above advice is general in nature and is only to be used as a guide. When choosing a compressor for your specific workshop/factory circumstances always heed the advice of the compressor manufacturer/supplier.
