The Vanair Air N Arc 300 gas rotary screw air compressor with generator and welder provides more efficient use of truck bed space and reduces cost by combining five power sources: a rotary screw air compressor, a 7 kW generator, a 300 AMP welder, a battery booster, and a battery charger all in one unit. Designed as a true two generator system, the Air N Arc 300 series allows multi-functioning such as welding and utilizing the generator at the same time for lights.
