Curtis Masterline

Since its inception in 1897, the Masterline has been 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

• 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 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

ROBUST QUALITY COMPONENTS

Built for increased longevity and 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

• Suction valve head unloaders for continuous running air compressors
