Frequently Asked Questions

What CFM (Cubic Feet per Minute) rating should I look for?

The ideal CFM depends on your intended use. For rapidly inflating large truck tires (35 inches or larger) or running air tools, we recommend systems with 3.0 CFM or higher at 0 PSI. For smaller tires or occasional top-offs, a compressor with 1.5 to 2.5 CFM may suffice. Higher CFM generally means faster inflation.

What is 'duty cycle' and why is it important?

Duty cycle refers to the percentage of time an air compressor can run within a given period (usually 1 hour) without overheating. A 100% duty cycle means it can run continuously without needing a cool-down. For heavy-duty use like airing up multiple large tires or operating air tools, a higher duty cycle (e.g., 50% or 100% at 100 PSI) is crucial for longevity and consistent performance. Lower duty cycles are fine for intermittent, light use.

Can I use an air tank with my built-in compressor?

Yes, many built-in air compressor systems benefit greatly from an auxiliary air tank. Based on our research, tanks store compressed air, allowing for a burst of high-volume air for tasks like seating tire beads or operating air tools more effectively. They also reduce the compressor’s run time, potentially extending its lifespan. Ensure your compressor is rated to handle the pressure requirements of your chosen tank.

What electrical considerations are there for built-in air compressors?

Built-in air compressors, especially high-performance models, can draw significant amperage. We recommend checking the compressor’s amperage draw and ensuring your truck’s electrical system, including wiring gauge and fuse rating, can safely support it. It’s often advisable to run a dedicated power wire directly from the battery with an appropriate in-line fuse or circuit breaker to prevent overloading existing circuits.

Where is the best place to mount a built-in air compressor on a truck?

The ideal mounting location depends on your truck’s make and model, and the compressor’s size and features. Common locations, based on owner feedback, include under the hood (if space permits and heat is managed), in a truck bed storage box, behind the rear seat, or custom fabricated mounts under the chassis. Prioritize locations that are protected from extreme elements, allow for good airflow for cooling, and are accessible for maintenance.
