Why VIAIR?
Top Sellers
Does the engine need to be running to operate the compressor?

The compressor needs a constant 13.8 Volts for optimal performance, and that is only possible with the engine running.

What is duty-cycle?

It’s the maximum continuous run time of the compressor, expressed in % of 1 hour.

Is a direct-drive motor better than a gear-drive motor?

Direct-drive motors deliver power straight to the piston rod, it is quiet and reliable. Gear-driven motors have an extra layer of friction, creating a louder system that’s prone to rapid performance decline due to deteriorating gear teeth.

From Road to Trail VIAIR's battery powered air compressor pumps are loved by daily commuters, families, and extreme off-road enthusiasts alike for their powerful, reliable performance in a small package. 12V Battery Clamps for Higher Performance Offroading applications have higher performance demands that cigarette lighter plugs are unable to meet. Enthusiasts prefer direct battery connections for their trucks, Jeeps and 4x4s because it accommodates the increased current draw of larger, more powerful compressors. While VIAIR does offer cigarette lighter models, we recommend compressors with battery clamps for serious for offroad use.
