The Vanair Air N Arc 300 hydraulic rotary screw air compressor with generator and welder has all of the advantages of being hydraulically driven with all of the advantages of a 40 CFM 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 Hydraulic allows simultaneous dual functionality. The system offers a small footprint for side pack or behind-the-cab mounting and is ideal for trucks with hydraulics already installed.
