Air N Arc® 300 Hydraulic ALL-IN-ONE Power System®


The Air N Arc® 300 Hydraulic All–In-One Power System® features the innovation of being hydraulically driven, while still offering all the advantages of the Air N Arc® 300 engine drive system including a 40 CFM rotary screw air compressor, 300 AMP welder, 300 AMP 12V charger and 12V/24V booster, and 7 kW generator. Designed as a true two generator system, the Air N Arc® 300 Hydraulic allows simultaneous dual functionality such as welding and generator for lights for nighttime service. The system offers a small footprint for side pack or behind-the-cab mounting and is ideal for trucks with hydraulics already installed, such as crane trucks.

Dimensions listed are not a complete representation of total space necessary.  Please consult Vanair for overall space and air requirements.

Product improvement is a continuing goal. Design and specifications are subject to change without notice or obligations.

Ratings above are approximate and are based on 120° F hydraulic fluid temperature. Add 400 PSI minimum to hydraulic requirements for hydraulic system peak pressure ratings. Machine hydraulic relief valve is set at 3200 PSI. Consult Vanair for specific details. Do not weld with the electrode holder connected to the negative port and the work piece connected to the vehicle. Bodily harm and equipment damage may occur.

Hydraulic System Requirements

All hydraulic ratings and pressures are at the machine and do not take into account the pressure drops of individual hydraulic systems. These
pressure drops need to be taken into account and added to the rating of the hydraulic pump and components. Vanair highly recommends
consulting a hydraulic supply expert for specifying the correct hydraulic pump size and type, oil reservoir size, hydraulic cooler, hydraulic
pressure relief, and other hydraulic supply components for your application. Please take into consideration the following: the hydraulic flow
and pressure requirements of the air compressor, the continuous hydraulic load when the compressor is running, the duty cycle and ambient
operating temperatures, and any other hydraulic equipment that may share the same hydraulic supply system (Vanair recommends a dedicated
pump and hydraulic circuit).
