Cummins Air Compressors
Cummins air compressors are critical components in heavy‑duty truck air brake systems. These compressors supply pressurized air used for braking, suspension, and other pneumatic systems across many commercial truck platforms. At Advanced Truck Parts, we provide replacement air compressors compatible with several Cummins engine families including ISX, X15, and ISB 6.7.

Cummins Air Compressors by Engine Platform
Most heavy-duty trucks powered by Cummins engines rely on engine‑driven air compressors to maintain proper air system pressure. The compressor works with the air dryer, reservoirs, and brake control valves to keep the vehicle’s pneumatic systems functioning correctly.
Cummins ISX Air Compressors
The Cummins ISX platform is widely used in long‑haul and vocational trucks. Air compressors mounted to the engine provide a continuous supply of compressed air required for brake operation and other air‑powered components.
- Cummins ISX CM870
- Cummins ISX CM871
- Cummins ISX CM2250
- Cummins ISX CM2350
These systems are commonly paired with Bendix‑style compressors designed for high durability in heavy‑duty trucking applications.
Cummins X15 Air Compressors
The Cummins X15 engine replaced the ISX platform in many newer trucks. These engines continue to use engine‑mounted compressors to maintain air pressure for the braking and pneumatic systems.
- Cummins X15 Efficiency Series
- Cummins X15 Performance Series
- Modern highway truck applications
Cummins ISB 6.7 Air Compressors
The Cummins ISB 6.7 engine is common in medium‑duty trucks and vocational equipment. These applications also rely on durable air compressors to maintain system pressure for braking and auxiliary air systems.
- Cummins ISB 6.7 CM2150
- Cummins ISB 6.7 CM2350
- Medium‑duty truck platforms
Common Air Compressor Failure Symptoms
- Slow air pressure build‑up
- Low air system pressure warnings
- Oil contamination in the air system
- Unusual compressor noise
- Frequent air dryer cycling
If the compressor cannot maintain proper pressure, braking performance and other pneumatic systems may be affected.
Verify Fitment Before You Buy
Air compressors vary by engine configuration, mounting style, and drive system. To confirm compatibility before ordering, provide:
- Engine Serial Number (ESN)
- Truck year / make / model
- Engine model (ISX, X15, or 6.7)
- Current compressor part number
This information helps ensure the correct compressor is selected for your Cummins-powered truck.
