FEATURES + BENEFITS
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 increases service life
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
- 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
Duplex
Duplex compressors are ideal when there are varying demand levels during operation. By alternating demand across two pumps, a duplex compressor also delivers longer pump life. The redundant pumps ensure you’ll always have air, eliminating maintenance downtime.
- Alternator control panel comes mounted with magnetic motor starters and thermal overload protection
- Compressors alternate during normal operation
- Both compressors run when system demands
- Duplex design reduces electrical cost and eliminates downtime
- Factory oil filled
