Air and AC Power with One PTO Opening Air Compressor and Weatherproof AC Generator

Totally contained underdeck within the truck’s frame rails, the patented Genair® dual power system replaces the need for separate engine-drive air compressors, generators, or power inverters by providing everything you need in a single integrated unit with one PTO opening. The Genair® is the perfect choice for plastic pipe fusion, TV pipeline inspection, and other on-board air compressor/AC electric power demands.
