Duplex Compressors

Duplex air compressors pair two compressor pumps on a single tank with alternating-lead controls for redundancy and capacity scaling without doubling tank footprint. This collection covers duplex reciprocating piston configurations from FS Curtis sized for shops requiring backup compressor capacity or higher peak CFM than a single pump can deliver. Both pumps share the tank but operate independently for true redundancy. Alamo Equipment is an authorized dealer with installation support and parts availability nationwide.
