The FS-Curtis ML7.5 Masterline Series represents the gold standard in heavy-duty reciprocating air compressor technology. Engineered for demanding industrial applications, this 7.5 HP vertical simplex compressor combines 80-gallon ASME-approved tank capacity with 28.7 CFM output at 175 PSI, delivering robust, continuous-duty performance for professional workshops, manufacturing facilities, and automotive service centers. Built with FS-Curtis's legendary Centro-Ring pressure lubrication and 100% cast-iron construction throughout all critical components, the ML7.5 is designed to outlast and outperform splash-lubricated alternatives and small rotary compressors in the most challenging working conditions.
Available in both single-phase (1/60/230V) and three-phase configurations (200-208V, 230V, and 460V), this vertical simplex unit offers exceptional flexibility to match your facility's electrical infrastructure. The C79 pump operates at slower speeds to maximize service life, while the space-saving vertical footprint (36" L x 30" W x 75" H) makes it ideal for shops where floor space is at a premium. Each compressor ships factory oil filled and ready for installation, backed by American manufacturing quality and FS-Curtis engineering expertise.

Why Masterline is Built to Last
The Masterline Series is the most robust, heavy-duty reciprocating air compressor lineup available. The perfect combination of quality components and efficient design make the ML Series rugged, affordable, and smart. Because every model is built tough to last a lifetime in demanding working conditions, the ML Series is an outstanding alternative to splash-lubricated reciprocating compressors and small rotary compressors. Choose higher quality. Choose superior durability. Choose ML Series pressure lubricated air compressors.
Centro-Ring Pressure Lubrication – Patented FS-Curtis Design
At the heart of every Masterline compressor is FS-Curtis's exclusive Centro-Ring pressure lubrication system, a proprietary technology that sets these compressors apart from the competition:
- Proprietary technology is an FS-Curtis exclusive
- Supplies pressurized oil internally to all bearings and critical wear surfaces through the rifle-drilled crankshaft and connecting rods
- Helps ensure maximum uptime and increase service life
100% Cast-Iron Where It Counts
100% cast-iron cylinders, cylinder heads, connecting rods, and crankshaft – all cast-iron where it counts for longer life with less maintenance:
- Some pumps claim 100% cast-iron yet still have aluminum cylinders, cylinder heads, connecting rods and crankshafts – not FS-Curtis
- Ductile cast-iron crankshaft and connecting rods are stronger, more corrosion-resistant and less likely to break
- Slow-turning pump increases pump life
- Rugged parts and construction for industrial performance
Quality Components – Built for 100% Continuous Duty
- Industry-leading stainless-steel valve assemblies for increased airflow and reliability
- Oversized tapered main roller bearings to ensure long life
- Premium finned intercooler maximizes heat dissipation
- Metal intake filter/silencer is superior to plastic
- Heavy-duty stamped-steel belt guard
- Suction valve head unloaders for continuous running air compressors
Key Highlights
- 28.7 CFM @ 175 PSI – Powerful airflow from the C79 pump for demanding applications
- 80-gallon ASME-approved tank – Vertical configuration maximizes capacity while minimizing footprint
- Centro-Ring pressure lubrication – Patented FS-Curtis technology for maximum uptime and longevity
- 100% cast-iron construction – Cylinders, heads, connecting rods, and crankshaft built for industrial duty
- Automatic start-stop control with UL-approved pressure switch and magnetic motor starter
Simplex Design for Straightforward Reliability
Simplex compressors are well suited for common applications where only one compressor is needed. The ML7.5 Vertical Simplex is designed to deliver consistent, reliable compressed air for single-location operations without the complexity of dual pump systems. This streamlined configuration means easier maintenance, straightforward troubleshooting, and dependable performance shift after shift.
