Industrial Gold CI7521E80V-CI10

Industrial Gold CI7521E80V-CI10 is a 7.5 HP two-stage reciprocating industrial air compressor delivering 28 SCFM on an 80-gallon vertical tank, wired for 208-230V single-phase. The CI7521 designation identifies a cast-iron two-stage pump in the Industrial Gold industrial lineup; the CI10 suffix indicates an integrated CI10 control package for pressure management and protection. Two-stage compression at 7.5 HP efficiently serves auto shops, maintenance facilities, and light fabrication environments with moderate air demand. The 80-gallon receiver reduces motor cycling and supports simultaneous light-tool operation. 208-230V single-phase wiring suits standard commercial service. Key gaps: rated PSI operating point, weight, duty cycle, and OEM datasheet URL not confirmed in current record.
