The FS-Curtis ML10 Duplex air compressor combines the legendary durability of the Masterline series with the efficiency and reliability of a duplex dual-pump configuration. Featuring two 10 HP motors with D97 pumps mounted on a 200-gallon ASME-approved horizontal tank, this powerhouse delivers 79.6 CFM at 175 PSI, making it the ideal solution for facilities with varying air demand. The duplex design intelligently alternates between pumps during normal operation and runs both when peak demand requires it, ensuring you always have air while dramatically extending pump life and reducing electrical costs.
Built for 100% continuous duty in the most demanding industrial environments, the ML10 Duplex represents the most robust, heavy-duty reciprocating air compressor technology available. Every component is engineered for longevity: Centro-Ring pressure lubrication, 100% cast-iron construction where it counts, and quality components throughout. This is an outstanding alternative to splash-lubricated reciprocating compressors and small rotary compressors, delivering superior durability and rugged, affordable performance that's built tough to last a lifetime.
Duplex Design: Smart Air Delivery for Variable Demand
Duplex compressors are ideal when there are varying demand levels during operation. By alternating demand across two pumps, a duplex compressor delivers longer pump life while the redundant pumps ensure you'll always have air, eliminating maintenance downtime. The ML10 Duplex comes equipped with an alternator control panel mounted with magnetic motor starters and thermal overload protection. Compressors alternate during normal operation, and both run when system demands peak capacity. This duplex design reduces electrical cost, maximizes uptime, and eliminates the costly downtime associated with single-pump failures.
Factory oil filled and ready to go, the ML10 Duplex is available in three-phase configurations at 200-208V, 230V, and 460V, each model delivering premium efficiency motor performance for maximum cost savings and reliability. With a 200-gallon horizontal tank, automatic start-stop control, and a 3-position alternator switch, this compressor offers the flexibility and intelligence your operation demands.
Centro-Ring Pressure Lubrication: Patented FS-Curtis Technology
Centro-Ring pressure lubrication is a proprietary technology exclusive to FS-Curtis. This patented design supplies pressurized oil internally to all bearings and critical wear surfaces through rifle-drilled crankshafts and connecting rods, helping ensure maximum uptime and dramatically increasing service life. Unlike splash lubrication systems, Centro-Ring delivers oil precisely where it's needed under pressure, reducing wear and extending the intervals between maintenance. This is advanced engineering that translates directly to lower operating costs and longer compressor life.
100% Cast-Iron Construction: All Cast-Iron Where It Counts
Some pumps claim 100% cast-iron yet still have aluminum cylinders, cylinder heads, connecting rods, and crankshafts—not FS-Curtis. The ML10 Duplex features 100% cast-iron cylinders, cylinder heads, connecting rods, and crankshaft for longer life with less maintenance. The ductile cast-iron crankshaft and connecting rods are stronger, more corrosion-resistant, and far less likely to break under heavy industrial use. Combined with a slow-turning pump design, the rugged parts and construction of the ML Series deliver true industrial performance you can count on day after day.
Quality Components Built for Continuous Duty
Every component in the ML10 Duplex is engineered for 100% continuous duty in demanding environments. Industry-leading stainless-steel valve assemblies maximize airflow and reliability. Oversized tapered main roller bearings ensure long life, while the premium finned intercooler maximizes heat dissipation for cooler, more efficient operation. The metal intake filter/silencer is far superior to plastic alternatives, and the heavy-duty stamped-steel belt guard meets OSHA standards for safe operation. Suction valve head unloaders support continuous running, and the dynamically balanced flywheel with slow V-belt drive further extends service life and reduces vibration.
Additional premium features include a magnetic motor starter, UL-approved pressure switch, ASME-approved safety relief valve and discharge valve, dial read-out pressure gauge, manual condensate tank drain valve, and a tank shut-off valve for easy servicing. With premium efficiency motors (three-phase only), a NEMA-1 alternator control panel, and standard two power source capability, the ML10 Duplex is the smart choice for facilities that demand reliability, efficiency, and American-made quality.
