The FS-Curtis ML15+ Simplex delivers 55.8 CFM at 175 PSI from a robust 15HP three-phase motor and C89 pressure-lubricated pump, all mounted on a durable 120-gallon ASME-approved horizontal tank. Built entirely in the USA with 100% cast-iron construction where it counts—cylinders, cylinder heads, connecting rods, and crankshaft—this compressor is engineered for 100% continuous duty in the most demanding industrial environments. With FS-Curtis's patented Centro-Ring pressure lubrication and premium efficiency motors, the ML15+ represents the pinnacle of heavy-duty reciprocating air compressor technology. This simplex configuration is ideal for applications requiring a single, reliable compressor delivering consistent performance day in and day out.
The Masterline Advantage: Built Tough to Last a Lifetime
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
The patented Centro-Ring pressure lubrication system is an FS-Curtis exclusive that sets the ML15+ apart from the competition. This proprietary technology supplies pressurized oil internally to all bearings and critical wear surfaces through the rifle-drilled crankshaft and connecting rods. By ensuring that every moving part receives optimal lubrication, Centro-Ring helps ensure maximum uptime and dramatically increases service life. You'll experience fewer maintenance interventions and longer intervals between service—a true testament to superior engineering.
100% Cast-Iron Where It Counts – All Cast-Iron 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. The ML15+ features genuine 100% cast-iron cylinders, cylinder heads, connecting rods, and crankshaft for unmatched durability. The ductile cast-iron crankshaft and connecting rods are stronger, more corrosion-resistant, and far less likely to break under load. Combined with a slow-turning pump design that reduces wear, these rugged parts and construction deliver true industrial performance that stands the test of time.
Quality Components – Built for 100% Continuous Duty
Every component in the ML15+ is selected and engineered for reliability in continuous-duty applications. Highlights include:
- Industry-leading stainless-steel valve assemblies for increased airflow and reliability
- Oversized tapered main roller bearings to ensure long life under heavy loads
- Premium finned intercooler that maximizes heat dissipation for cooler operation
- Metal intake filter/silencer – superior to plastic for durability
- Heavy-duty stamped-steel belt guard – OSHA-approved and fully enclosed
- Suction valve head unloaders for continuous-running air compressors
- Magnetic motor starter for reliable, safe operation
- Automatic Start-Stop control for convenient, hands-free operation
- Dynamically balanced flywheel for smooth, vibration-free performance
- Slow V-belt drive for quiet operation and extended belt life
- Premium Efficiency Motors (3-phase only) to reduce energy costs
The unit comes factory oil-filled and is equipped with a dial read-out pressure gauge, UL-approved pressure switch, ASME-approved safety relief valve, ASME-approved discharge valve air service valve, manual condensate tank drain valve, tank shut-off valve, and Dual Control with pilot valve (ML5-ML15 D97 Pump). All backed by an ASME-approved 120-gallon horizontal air receiver and housed in a robust NEMA-1 control panel.
