Deep Dive into the Lineup

CPS 110-100

The perfect entry point for smaller crews. It provides ample power for a single 90lb breaker or multiple smaller pneumatic tools while maintaining a tiny footprint on the job site.

CPS 175-100 & CPS 175-100 T3

The 175 series is the “Goldilocks” of the CP range. It offers a significant jump in airflow to power two tools simultaneously.

• The T3 Variant: Specifically designed for users who prefer the simplicity and ease of maintenance associated with Tier 3 mechanical engines.

CPS 185-100

The flagship of the small mobile range. With 185 cfm, this unit is the industry standard for powering two 90lb hammers, sandblasting equipment, or pneumatic piping projects. It’s the ultimate balance of power-to-weight ratio.

Technical Highlights

• Working Pressure: 100 psig (7 bar)

• Engine Brands: Reliable powerplants (such as Kubota or Perkins)

• Cooling System: High-performance cooling ensures operation in extreme ambient temperatures.

  CP Performance Tip: Always check your tool’s CFM requirements. Running a 185-100 ensures you have the “overhead” needed to maintain steady pressure even during continuous heavy-duty use.
