I recently bought a media cabinet and I already had a 30 gallon compressor. I started a trial run with the cabinet on a pair of calipers. I got no where. The media barely put a dent in the caliper paint. I sprayed for 30 minutes and completed an area about 3"x3". The media was glass bead 70 grit and the compressor was set at 100 psi.
I believe my issue may be the amount of air the compressor moves, and not the PSI. What is the recommended amount that will work on brake calipers? My compressor is a 5.2 CFM. Is glass bead appropriate for enamel paint? What size compressor do I need? What is everyone else using? |

Most decent shop grade blast cabinets need a minimum of 15CFM and a constant over 100 psi. .
My Professional Curtis double stage compressor 20 CFM can barely keep up with my cabinet and drops to 90 psi running continuously on big blast jobs. That is also affected by the size of air jet and nozzle your gun has . . Best to use a single stage compress , not double, on a blast cabinet as it will keep up pressure better. . |
