Genair Air Compressor / Generator

The Genair® is an underdeck unit that combines the power of a 125 to 185 cfm air compressor with the convenience of a patented, integral 7,200 to 11,600-watt AC Genairgenerator. Whether you need an air compressor only, an AC generator only, or your application demands that you run them both at the same time, the Genair® system maximizes the power of your truck’s engine by safely enabling you to access both pneumatic and electic power via your single PTO drive. Precise frequency controls keep output regulated within two percent.

The Genair® system couples directly to the rear of the rotary screw air end. This provides constant power input without belts, pulleys, or tensioning devices. The Genair® also eliminates the need to replace your truck’s alternator, belts, and sheaves to install a power inverter.

Ideal for pipeline sewer inspection, plastic pipe fusion, auxiliary lights, and on-board air compressor and AC electric power requirements.
