Designed specifically for Class B RVs.

Tires are the foundation of your home while on the road. That’s why tire pressure maintenance is essential for all RVers.

The VIAIR 89P-RVS is a compact 12-volt portable tire inflator specifically designed for Class B RVs. This essential RV tire inflator will fill most Class B tires from 80 to 90 PSI in less than 2 minutes. The 89P-RVS features a new and improved longer air hose to reach your Class B tires. 

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. Easily check tire pressure by using the gauge located on the top of the unit. Each tire inflator comes equipped with hoses long enough to reach your RV tires, a convenient carry bag, and all necessary components. Comes with a 1 year warranty.
