Capitano II and Mariner II The Capitano II and Mariner II compressor systems are very utilitarian. Both utilize one of our performance proven three stage pressure lubricated compressors with capacities of 6.0 to 8.4 SCFM Charge Rate and delivery pressures up to 5000 PSIG. Packaging can be as spartan as a portable compressor or as sophisticated as our Bauer Classic II design.
