20 l / min @ 200 bar. Now that _is_ big!


I'd say about 30 l / min actually (but not quite that pressure) A
pressure pot can be used usefully with a 10l/min compressor, but
you're not getting the same sand delivery rate. If you have small
enough nozzles, you can even throttle back to a rate that allows
continuous running, still on a D-I-Y compressor. Bigger nozzles though
need enough airflow to keep the sand moving, so you're limited to an
intermittent duty cycle.
