FS-Curtis CT7.5

FS-Curtis CT7.5 is a 7.5 HP two-stage splash-lubricated piston compressor with the cast-iron CT75 pump, rated 24.2 SCFM at 175 PSI on an 80-gallon vertical ASME tank. The CT75 pump is the next-size-up in the CT line over the CT5’s CT55 and shares the same ISO 9001 ductile-iron crankshaft, stainless-steel reed valves, and 100 percent cast-iron construction. Standard configuration is 230V single-phase, with a 230/460V three-phase variant for shops with three-phase service. The CT7.5 fits naturally as the upgrade for a small shop that has been thermal-cycling a 5 HP unit, or as the right size for a 2-3 bay auto shop on single-phase service. FS-Curtis (formerly Curtis-Toledo) backs the pump with a 2-year warranty extendable to 5 years with registration, and offers strong dealer support for parts and service. Best for 2-3 bay auto and tire shops, mid-size body shops, woodshops with continuous spray demand, and small fabrication shops.
