Product Review: VIAIR Air Compressor 450P-RV

“Tire air levels are important, a VIAIR air compressor is a must have for every recreational vehicle.”
RV Living Journey

After having to deal with a deflated tire issue as mentioned in First Stop: Torry Island Campground and having no direct means to alleviate the issue. It came as a must to acquire a portable air compressor to fill tires with air as needed. After weeks of continuous online research reading reviews, forums, and articles, it was settled that the VIAIR 450P-RV Air Compressor would be the one for purchase.

The VIAIR 450P-RV is one of VIAIR’s top of the line portable air compressors capable of airing tires as large as 42” and up to 150 PSI. The VIAIR portable compressor is powered by 12 volts DC. It boasts 100% duty cycle unit and can be operated up to 40 minutes at a time before needing rest. Being connected to the battery, the compressor can draw upwards of 23 amps, so the manual states the engine must be running.

One of the major features is the automatic shut-off function which comes into play in between tire fills. While a typical portable air compress must be turned off between tire fills, this saves the hassle of running back and forth to toggle the switch.
