Buyer’s Guide: What to Consider
Choosing the right onboard air compressor depends on your rig, tire size, and how you use air. Here are five key factors to consider before you buy.
- Duty Cycle: Look for 100% duty cycle if you plan to run air tools or inflate multiple tires. Lower duty cycles (33%) are fine for occasional use but will overheat with continuous operation.
- CFM Output: Higher CFM means faster inflation. For 35-inch tires, aim for at least 5 CFM. For larger tires or air lockers, consider 10+ CFM to save time and reduce strain.
- Max Pressure: Most compressors hit 150 PSI, which is plenty for tires. If you need to seat beads or run high-pressure tools, ensure the compressor can maintain that pressure consistently.
- Mounting and Portability: Decide between a permanent onboard system with a tank or a portable unit. Tank systems offer reserve air but take up space. Portables are flexible but require setup each time.
- Power Source: 12V compressors run off your vehicle's battery, but check amp draw. Some units can be hardwired, while others use alligator clips. Cordless options offer convenience but limited runtime.
Conclusion
Your onboard air compressor is a lifeline on the trail. Whether you opt for a tank system like the VIAIR or a portable powerhouse like the BUNKER INDUST, the key is matching the compressor’s output to your needs. Think about duty cycle, CFM, and how you’ll mount it.
For most overlanders, a dual-cylinder portable with 150 PSI and thermal protection offers the best balance of performance and convenience. If you run air tools or lockers, invest in a tank system. Choose wisely, and you’ll never be stuck with a flat tire again.
