Vanair PTO Drive Powers Smart Underdeck Systems
Sponsored by Vanair®
Most fleets don’t need more tools — they need smarter mobile power solutions that save weight, open space, and keep uptime high.
That’s exactly what the Vanair® PTO Shaft-Driven Underdeck ALL-IN-ONE Power System® delivers — a PTO drive, engine-driven underdeck air compressor platform that replaces six machines with one seamless install.
In this breakdown, we’ll show how Vanair underdeck air compressors work, what they replace, and why they’re redefining mobile power for modern fleets and service trucks.
The Vanair® Underdeck ALL-IN-ONE Power System — 2024 Equipment Today Top 50 New Product Award Winner.
Award-Winning Innovation
The Vanair® PTO Shaft-Driven Underdeck ALL-IN-ONE Power System® earned Equipment Today’s 2024 Contractors’ Top 50 New Product award for changing how fleets think about power.
It replaces multiple bolt-ons, cuts up to 2,000 lbs, and delivers full mobile power through one engine-driven PTO system — all from a single underdeck air compressor package.
From Six Machines to One
Picture a tire service truck the old way:
Compressor bolted on top
Generator eating bed space
Portable welder strapped down
Battery booster buried in shelves
Charger tucked in a side box
Hydraulic system crammed between it all
That’s six machines. Two thousand pounds. A cluttered bed and constant downtime.
Now imagine all that — compressor, generator, welder, booster, charger, hydraulics — powered by one Vanair underdeck air compressor system mounted under the truck.
That’s the Vanair® Underdeck ALL-IN-ONE Power System®.
You get your bed back.
Your techs move faster.
Your truck lasts longer.
Your fleet runs smarter.
Simplifying the Power Game
For years, fleets have stacked bolt-ons like it’s 2005 — more boxes, more wiring, more maintenance.
Every add-on adds weight, vibration, and cost. Over time, that means higher fuel use, overloaded GVWR, and premature failures.
Vanair® flips that model.
Instead of stacking systems, their engine-driven underdeck air compressor platform powers everything from a single PTO drive.
What It Replaces
125–185 CFM underdeck air compressor
10 kW generator
330 A welder
12 V / 24 V battery booster (optional 36 V / 48 V)
12 V / 24 V charging (optional 36 V / 48 V)
Up to 30 GPM @ 2,000 PSI hydraulic power
This isn’t a bolt-on bundle — it’s a full Vanair power system for service trucks, engineered to work together, live under the body, and free your truck bed.
No tanks blocking drawers.
No holes in fenders.
No wasted space.

Cleaner, Faster, Smarter
Traditional installs are complicated. Each add-on needs separate wiring, mounting, and venting — driving up labor time and cost.
With Vanair underdeck air compressors, everything runs off one PTO drive and engine-driven system.
It uses shared:
Mounting points
Fuel lines
Wiring harnesses
Hydraulic connections
Result: cleaner installs, faster builds, and less maintenance.
Fleet managers report fewer shop visits, better uptime, and simpler specs — all from one underdeck unit.
