We recommend Sparmax compressors for their reliability and value for money.
When you are thinking of buying a compressor keep in mind what you will be using it for. For example will you be painting cakes or t shirts? The latter would require you get a compressor with twin motors and a holding tank because you will be requiring larger volumes of air. You could even add another airbrush and the compressor could cope with the demand.Where as if you are doing cakes, nails, illustrations etc you may need a smaller compressor because you wont need such a big capacity.
Make sure your compressor has a moisture trap and regulator. This means you have extra control over how much air pressure you require. A moisture trap is an essential and eliminates a lot of issues that come from working in warm conditions.
