Testing an SB28 blast pot with built in vacuum

Thanks for the demo my friend!

Keen on this. Can you advise what performance I would get out of a 14cfm (9.5cfm free air delivery) compressor?

Hi, it wouldn't work very well at all to be honest. You need much bigger, I would say 18cfm upwards with 150/200 litre tank
