Vanair PTO Shaft-driven Underdeck ALL-IN-ONE Power System is the Lifeline of Portable Jobs

This solution provides a whopping six forms of power, allowing operators to use a wide range of portable tools in remote worksites.


Vanair has introduced the PTO Shaft-Driven Underdeck ALL-IN-ONE Power System for construction projects. Vanair’s new system offers power accessibility for professionals and six forms of power, positioning it as a versatile solution for a wide variety of work trucks and related applications.

The PTO Shaft-Driven Underdeck ALL-IN-ONE Power System has been designed to integrate beneath the vehicle chassis, opening cargo space.

“Our UDSM ALL-IN-ONE Power System streamlines six independent machines into a single unit with one footprint. With the new Underdeck ALL-IN-ONE Power System, we deliver the same comprehensive power, including welding capabilities, without encroaching on any vehicle bed space,” said Ralph Kokot, chief executive officer of Vanair.

Six Forms of Power

  • 125-185 cfm rotary screw air compressor  
  • 10 kW generator
  • 330A welder
  • 12V, 24V and optional 36V and 48V battery boosting capabilities
  • 12V-24V and optional 36V and 48V battery charging capacity
  • Up to 30 gpm @ 2,000 psi of hydraulic-driven power

With Vanair’s underdeck system, users can now replace six separate pieces of equipment, providing additional bed space, maneuverability, reduced maintenance requirements, free vehicle hitches and a weight savings of more than 2,000 pounds. The new design also uses Vanair’s new Sansgear belt drive for the hydraulic system.

Vanair understands the need for professionals to be prepared for wherever the job takes them. With its PTO Shaft-Driven Underdeck ALL-IN-ONE Power System, jobsite personnel will be equipped with the tools needed for welding, powering essential equipment and jump-starting other vehicles.

“Vanair continues to be at the forefront of innovation with our PTO Shaft-Driven Underdeck ALL-IN-ONE Power System. We understand the critical need for reliability and efficiency in equipment for on-the-job performance,” said John Dunn, strategic manager, Underdeck and Utility at Vanair.

“This system not only offers unmatched power and functionality but also ensures minimal downtime, which is crucial for professionals who rely on dependable equipment to get the job done.”

Design and Performance

The Vanair patented and patent-pending, designs have led to innovations that elevate the performance of its PTO Underdeck Mobile Systems. One such feature is the XERO Rapid Blow Down Tank design, which allows for immediate compressor disengagement and reengagement with zero blow-down time. This tank design eliminates the need to wait for the system to blow down completely, preventing oil carryover issues. Moreover, the XERO Tank permits up to a 15% angle of operation from side-to-side or front-to-back, offering versatility and adaptability on the jobsite.

For reliability and security, Vanair equips all its PTO Shaft-Driven Underdeck Power Systems with the FailSafe Dual Sensory Redundancy System as a standard feature. This system provides an uninterrupted power supply by switching to the backup unit in the event of a thermistor or transducer sensor failure. Furthermore, professionals can opt for the optional ThermalGuard Weather Protection Kit, a patented design that preheats the compressor oil and regulators using the vehicle’s warm engine coolant. This feature prevents oil starvation and freeze-ups during frigid conditions.

“We take great pride in offering unmatched cost savings and performance with our UltraLife Air/Oil Separator Element. This innovative element sets new industry standards with its extended lifespan of 6,000 hours, delivering up to six times more separator life compared to other units on the market,” added Dunn.
