Deep, surface-supplied commercial diving operations call for our 50 CFM and higher (+1416 L/min) heavy-duty, low pressure compressors that are built for offshore diving and for putting multiple divers in the water. The Quincy 5120 is our primary block for these packages, producing 85 to 95 CFM (2407-2690 L/min). For more CFM we are now supplying rotary screw packages that can deliver hundreds of CFM (over 2830 L/min). We can design a heavy-duty package to meet your specific needs.
