As quiet as a ventilation fan humming, these compressors power drills, saws, and other tools without the headache. They don’t require lubrication, so there’s no risk of oil contaminating the air or downstream filters—reducing maintenance and downtime. Compact and lightweight compared to standard air compressors, use their handle to move them where you need and store them when you’re finished. As single stage compressors, they’re best for infrequent use. Plug them into a standard outlet. They turn on when tank pressure drops to the actuation point and off when it reaches the maximum.
