Paccar Air Compressors
Paccar air compressors are key components in heavy-duty truck air systems, generating compressed air required for brake systems, air suspension, and other pneumatic functions. Consistent compressor performance helps maintain stable air pressure and safe vehicle operation. At Advanced Truck Parts, we supply replacement air compressors compatible with Paccar MX-11 and MX-13 diesel engines used in Kenworth and Peterbilt trucks.

Paccar Air Compressors for Truck Air Systems
Heavy-duty trucks rely on compressed air systems to operate essential components such as air brakes, suspension systems, and auxiliary pneumatic equipment. The air compressor continuously produces pressurized air that is stored in air tanks and distributed throughout the truck.
Paccar MX-13 Air Compressors
The Paccar MX-13 engine is widely used in Kenworth and Peterbilt highway trucks. Air compressors used with MX-13 engines must deliver consistent air pressure during long-haul operation and extended engine load.
- Paccar MX-13 diesel engines
- Kenworth T680 and related platforms
- Peterbilt 579 highway tractors
- Long-haul fleet vehicles
Paccar MX-11 Air Compressors
The Paccar MX-11 engine is commonly found in regional haul and weight-sensitive truck applications. Compressors used on this platform must maintain reliable air pressure for brake systems during frequent driving cycles.
- Paccar MX-11 diesel engines
- Regional haul trucks
- Commercial fleet vehicles
Common Air Compressor Failure Symptoms
- Low air pressure in the brake system
- Slow air tank refill times
- Air leaks or oil carryover
- Unusual compressor noise
- Air system warning indicators
Air compressors wear over time due to continuous operation, heat exposure, and internal component fatigue. Replacing a failing compressor helps restore proper air pressure and maintain reliable brake system performance.
Verify Fitment Before You Buy
Air compressors may vary depending on engine configuration, mounting design, and truck model. To confirm compatibility before ordering, provide:
- Truck year / make / model
- Engine model (MX-11 or MX-13)
- Current compressor part number
- Photos of the compressor or ID tag if available
This information helps ensure the correct Paccar air compressor is selected for your truck.
