The FS-Curtis ML20+ Simplex Air Compressor delivers 20 horsepower and 79.3 CFM at 175 PSI in a rugged, horizontal tank-mounted configuration designed for demanding industrial environments. Built around FS-Curtis' renowned Masterline platform, this 200-gallon ASME-approved tank system combines proven pressure lubrication technology, 100% cast-iron construction where it counts, and premium components engineered for 100% continuous duty operation. Whether you're running a high-volume shop, manufacturing facility, or production line, the ML20+ provides reliable, efficient compressed air with minimal maintenance and maximum uptime.
Simplex compressors like the ML20+ are ideally suited for applications where a single, dependable compressor meets all operational needs. With its factory-installed magnetic motor starter, automatic start-stop control, and NEMA-1 control panel, this unit is ready to integrate seamlessly into your facility. Available in multiple three-phase voltage configurations—200-208V, 230V, and 460V—the ML20+ adapts to your existing power infrastructure. Premium efficiency motors and a slow-turning C98 pump ensure energy savings and extended service life, making this compressor a smart investment for long-term reliability.
The Masterline Advantage: Built Tough to Last
Masterline 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
Centro-Ring pressure lubrication is a proprietary technology and FS-Curtis exclusive that sets the ML20+ apart from the competition. This patented system supplies pressurized oil internally to all bearings and critical wear surfaces through the rifle-drilled crankshaft and connecting rods, ensuring that every moving part receives the lubrication it needs under load. The result? Maximum uptime, reduced wear, and dramatically increased service life.
- Proprietary technology available only from FS-Curtis
- Delivers pressurized oil through the rifle-drilled crankshaft and connecting rods to all bearings and critical wear surfaces
- Helps ensure maximum uptime and significantly increases service life
100% Cast-Iron Construction Where It Counts
The ML20+ features 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. This commitment to heavy-duty materials ensures that your compressor can handle the rigors of industrial use, day in and day out.
- Ductile cast-iron crankshaft and connecting rods are stronger, more corrosion-resistant, and less likely to break under stress
- Slow-turning pump increases pump life and reduces wear on internal components
- Rugged parts and construction deliver industrial performance you can count on
Quality Components – Built for 100% Continuous Duty
Every component in the ML20+ is selected and engineered for reliability and longevity. From the industry-leading stainless-steel valve assemblies that increase airflow and reliability, to the oversized tapered main roller bearings that ensure long life, this compressor is designed to run continuously without compromise. The premium finned intercooler maximizes heat dissipation, while the metal intake filter/silencer (superior to plastic alternatives) and heavy-duty stamped-steel belt guard add to the overall durability.
- 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 provides robust protection
- Suction valve head unloaders for continuous running air compressors
