FS-Curtis C79A bare air compressor pump is engineered for high-demand applications where durability, reliability, and long service life are critical. As part of FS-Curtis’s respected “Masterline” series, the C79A delivers exceptional performance in some of the most challenging shop, industrial, and commercial environments.

FS-Curtis C79A Bare Air Compressor Pump features a heavy-duty cast-iron construction throughout the crankcase, cylinders, and cylinder heads, ensuring superior strength and heat dissipation. Designed for true industrial use, this pump is built to run harder, cooler, and longer than lighter-duty alternatives, offering extended operating life even under constant workloads.

This model uses a two-stage compression system, compressing air in two steps to improve efficiency, reduce discharge temperatures, and deliver higher pressures with less moisture buildup. The design reduces internal heat and stress, helping the pump maintain optimal performance and longevity. The C79A is ideal for supporting a wide range of air tools, production machinery, and heavy-duty shop equipment.

The splash lubrication system provides continuous, reliable lubrication to all critical moving parts, reducing friction and wear without the complexity of pressure lubrication systems. Combined with the low RPM operation and balanced, ductile iron crankshaft, the C79A runs cooler and quieter, resulting in smoother operation and reduced maintenance requirements over the life of the pump.

An oversized flywheel further enhances cooling and lowers vibration, while the intercooler between stages improves compressor efficiency by reducing the air temperature before it enters the second-stage cylinder. Every component is precision-machined to FS-Curtis’s strict standards, ensuring consistent quality and performance across every unit.

Key Features of the FS-Curtis C79A Bare Pump:

  • Heavy-duty cast-iron crankcase, cylinders, and heads for maximum durability

  • Two-stage compression design for efficient, cooler operation

  • Splash-lubricated system for reliable protection and low maintenance

  • Balanced, ductile iron crankshaft for smoother and quieter operation

  • Low RPM design to minimize heat and stress on internal components

  • Intercooler between stages for improved performance and moisture control

  • Oversized flywheel for better cooling and reduced vibration

  • Built for continuous duty in industrial and commercial settings

Whether you are upgrading your compressor system or replacing a worn-out unit, the FS-Curtis C79A bare pump is built to deliver serious performance with unmatched durability. Backed by FS-Curtis’s century-long reputation for excellence, the C79A is ready to be the heart of your compressed air system for years to come.
