Buyer’s Guide: What to Consider

Choosing the right on board air compressor depends on your vehicle, tire size, and usage. Here are five key factors to consider before buying.

• Flow Rate (CFM): Higher CFM means faster tire inflation. For large tires, look for twin-motor compressors with at least 1.5 CFM.
• Duty Cycle: Indicates how long the compressor can run before cooling. Off-road use often requires 50% or higher duty cycle.
• Maximum Pressure (PSI): Most tire compressors reach 100-150 PSI. Ensure the unit can handle your tire's recommended pressure.
• Build Quality & Sealing: Look for anodized cylinders and sealed motors to resist dust, moisture, and heat for long-term reliability.
• Installation & Accessories: Consider included wiring, hoses, and mounting hardware. A longer hose makes reaching all tires easier.

Conclusion

Each of these five compressors serves a different need. The ARB CKMA12 is a proven workhorse for locker and tire duties, while the BUNKER INDUST excels with big tires. The VIAIR Ultra Light offers a complete tank system, and the GELUOXI provides a compact high-flow option.

For a complete ready-to-install setup, the ARB Inflation Kit bundle is hard to beat. Consider your typical terrain, tire size, and whether you need a tank to make the best choice for your rig.
