115 volt compressor. This compressor never needs oil or lubrication. On/off switches (not available on Badger's previous diaphragm compressors) are conveniently located directly on the units. Four attached suction cup feet eliminate compressor "movement". Each unit operates one airbrush, with a pressure of 30 PSI for most airbrushes. Portable and light, weighing only 9 pounds, this compressor includes a durable 6 foot cord with three prong plus and a 1/10 horsepower motor.
