Tires are the foundation of your home while on the road. That’s why tire pressure maintenance is essential for all RVers. This essential tire inflator features a newly revised 40” 90-degree twist on chuck to make it easier to fill tires while standing. The 450P-RVS will inflate most Class A RV tires from 80 to 90 PSI in just 50 seconds.

The “RVS” line is designated as “RV-Safe” because they are specifically designed and tested for the RV market. Having this indispensable tire inflator in your RV at all times will prevent wasted time locating the nearest gas station, and reduces your risk being stuck on the side of the road.

How to use: To use this compressor, simply attach the heavy-duty battery clamps to the RV’s battery and start the engine. Connect the tire chuck to a tire valve stem and turn the unit on. The 450P-RVS comes with a close-ended gas station-style air gun for added convenience. Each tire inflator comes equipped with hoses long enough to reach your RV tires, a convenient carry bag, and all necessary components.

Portable compressors with automatic shutoff provide an auto stop/start function similar to newer vehicles turn off when at a stop. This feature comes 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 going back and forth from the tire to the portable compressor to turn the unit on and off. Automatic portables will save you time & effort to get tires inflated quickly.
