As an automotive hobbyist who likes working on my cars, I recently tested the Viair 45040 air compressor kit to see how it performed for tasks like filling tires and powering tools. In this review, I’ll share my hands-on experience using this compressor kit for garage projects.

One of the key features I noticed was the 450C compressor’s max working pressure of 150 PSI. This higher pressure capacity provided ample power for most common automotive uses compared to smaller portable compressors. It had no problem rapidly inflating tires or running air impact wrenches during testing.

The compressor is rated for 1.66 CFM free flow at 0 PSI, which I found provided decent airflow for intermittent use tools. However, when running high-consumption tools continuously, the 2.3-gallon tank started to drop pressure more quickly than larger compressors.

One useful inclusion is the 40 amp relay with mounting tabs. An appropriately sized relay and fuse is important for safety and proper installation when wiring compressors. This ensures the electrical load is handled properly.

Overall, I found this a solid air compressor kit for automotive home gamers looking for portable power to fill tires and operate tools for DIY projects. The 450C compressor provides ample pressure for most tasks. Just keep in mind the compact tank size means it’s better suited for intermittent versus sustained high-demand airflow. Let me know if you have any other questions!
