The Better Built Compressor
Quality and industrial durability are built into each cast iron pump to give you a solid return on your compressor investment.

Challenge Air Compressor Components

Suction Valve Head Unloaders
For continuous running air compressors, unloader lets unit idle load-free until air supply drops to cut-in pressure; automatically lets unit idle again after high pressure limit is reached.

Heavy Duty Stainless Steel Valves
Standard on all CA Series compressors. Lapped to optical flatness for high efficiency and extended wear. All CA Series valves are oversized and designed for high flow.

Large Intake Filter Silencers
For quiet operation and provides maximum particulate protection.

Deep Finned Cylinders & Heads
Ensures cool, vibration free operation and long life.

Cast Iron Cylinders
Precision bored for high performance and low oil carry-over.

Rings
Long-life industrial design compression and oil control rings for maximum performance.

Cast Iron High Tensile Strength Rods
With replaceable rod bearings and pin bushings. Machined to close tolerances for many years of service.

Ductile Iron Crankshaft
Dynamically balanced, precision-machined, and ground. Assures extended running life for all internal bearings and wearing surfaces.

Cast Iron Crankcase
For strength and durability.

Balanced Flywheel
For smooth operation with high volume airflow to cool heads and cylinders.

Large Main Roller Bearings
Precision fit to hold alignment of all rotating parts.

Oil Sightglass
Conveniently located for reading of oil level in crankcase.

DEPENDABLE, HIGH QUALITY CAST IRON CONSTRUCTION

For more than a century, FSCURTIS has earned the reputation of building the most rugged industrial duty equipment you can buy.
