Hateful McNasty
Grand HAMster
I don't know my math shots differentThe cs4 is excellent and 6.8 is actually a 74 cubic foot scba tankloooots of air
The Aluminum 80 cu ft (11.1 liters) cylinder is the staple of the diving industry.
So 6.8 would be a 45 cuft +/- ( call it 1/2 the 80)
Still that's not bad on that type compressor. I'd think pretty ok
