RV Portable Compressors for Tire Inflation
Viair 400P-RV & 450P-RV
Our RV Automatic portable air compressors will inflate tire sizes up to 275/80/22.5 tires to a max of 150PSI with ease. While these units are intended for RV use, they can also be used for virtually any tire since they come with accessories for many different inflation needs.
VIAIR’s Automatic tire inflators make tire filling simple! While most portable air compressors must be turned off between tire fills and checking tire pressure, the compressors only operate while the trigger on the inflation gun is pulled. This will certainly save you much needed time, making the overall process of filling your tires seem effortless.

60 Ft. Coil HoseThese compressors come with (2) 30 ft coil hoses for a total length of 60 feet which should be enough length for any size motor home, RV, or trailer. |
Special Tire AttachmentsThe RV tire inflators include a 45 degree chuck and a 90 degree twist on chuck for easy access to rear dually tires where it is hard to get to the inner tire's valve stem. They also come with a gas station style inflation gun with 160psi gauge. |
Automatic Shut Off FunctionPortable compressors with automatic shutoff come into play when moving from tire to tire, and when checking tire pressure in the middle of a tire fill. A typical portable compressor must be turned off between tire fills, and anytime you want to check tire pressure. If you aren’t near the compressor, this can turn into running laps back and forth to the portable compressor to turn the unit on and off. Automatic portables do not work in this fashion and will save you time & effort to get tires inflated. |

| Manufacturer's Notes | The 400P-RV is our fastest filling RV compressor, but can only run continuously at 100psi for 20 mins before needing to cool down. | The 450P-RV is a slower filling compressor, due to the lower CFM, but it can be run continuously at 100psi for up to an hour before needing to cool down. |
