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
