Portable Gasoline-Powered Air Compressors


With Handle	With Handles and Wheel

No need to hunt for an outlet—these gasoline-powered compressors power your tools anywhere you go. Their engine is manufactured to tight tolerances, so it’s generally quieter, lasts longer, and requires less maintenance than other engines. As single stage compressors, they’re best for infrequent use. These compressors turn on when tank pressure drops to the actuation point and shut off when it reaches maximum pressure. Pair them with the listed oil (sold separately) to maintain performance and efficiency.

Import regulations restrict sales to the listed jurisdictions.

Continuous Duty—Compressors for continuous duty can run without a cooling period. They’re designed for applications that require a constant supply of compressed air.

Intermittent Duty—Compressors for intermittent duty require a cooling period between uses so they don’t overheat.

Gasoline-Powered Air Compressors

Mount these air compressors on your truck for compressed air where electrical power isn’t available. They're great for powering large equipment out in the field, such as lifts used to move heavy objects. Their engine is manufactured to tight tolerances, so it’s generally quieter, lasts longer, and requires less maintenance than other engines.

These air compressors use pistons to compress air in two stages, which generates higher pressures and flow rates than single-stage compressors. This two-step process—compressing air, cooling it, and compressing it again—prevents heat buildup and reduces wear. They turn on when tank pressure drops to the actuation point and shut off when it reaches maximum pressure.

Compressors require SAE 30 synthetic oil (sold separately) to maintain their performance and efficiency.
