If you operate a Class 8 truck with a Cummins N14 engine and need a reliable replacement air compressor, you've come to the right place. The Cummins N14 Air Compressor for sale at Vaz Auto Solutions has gone through thorough functional testing and mechanical inspection to deliver consistent air supply to your truck's air brake system, air suspension, and pneumatic accessories.
Our used Cummins N14 air compressors are tested for efficiency and durability. Each unit is thoroughly checked for operational integrity including bench-test output pressure, lubrication passage operation, gear drive engagement, and visual inspection of mounting flange and cooling jacket. You get competitive pricing on a proven-functional air compressor with documented donor history.
The Cummins N14 is one of the most successful Class 8 truck diesel engines ever produced. Manufactured from approximately 1991 to 2000, the N14 is a 14-liter Inline-6 diesel and is the direct mechanical predecessor to the modern Cummins ISX / X15 family. The N14 air compressor on this listing is compatible with the entire N14 production lineup:
| Detail | Description |
|---|---|
| Cummins N14-310 | 310 hp variant for moderate-duty applications |
| Cummins N14-370 | 370 hp variant for general-duty long-haul |
| Cummins N14-435 | 435 hp variant for heavier long-haul service |
| Cummins N14-460 | 460 hp variant for high-output long-haul and vocational |
| Cummins N14 Plus | 500 hp top-of-line variant (the legendary "N14 Plus" engine) |
The N14 air compressor is mechanically gear-driven off the engine front cover and is largely the same physical unit across all N14 power ratings. Confirm donor variant when ordering for ECM-related parasitic load matching.
The Cummins N14 was offered across the entire Class 8 truck OEM landscape during 1991-2000 production. This air compressor fits any Class 8 truck originally equipped with a Cummins N14 engine:
Note: This is a Cummins N14-specific air compressor. It is not interchangeable with Caterpillar (CAT C15, CAT 3406), Detroit Diesel (Detroit 60 Series, DD13/DD15), or Mack MP-series engines, which use their own different OE air compressors. Tell us your specific donor engine when ordering.
Beyond Class 8 highway trucks, the Cummins N14 also powered:
These industrial / marine N14 engines use the same air compressor design (where the application requires compressed air output), making this listing cross-compatible with non-on-highway Cummins N14 service applications.
