MODEL 6450: ULTRA HEAVY-DUTY - HIGH CAPACITY ONBOARD AIR SYSTEM

THE ULTIMATE POWERHOUSE

Step up to elite onboard air performance with the premium Model 6450 system. Driven by our flagship waterproof high-output 100% duty cycle compressor and anchored by a massive 5-gallon air tank, this ultra heavy-duty configuration is meticulously engineered for maximum air volume and non-stop recovery performance. It represents the ultimate power hub for demanding automotive, commercial, and extreme off-road applications where a lack of lung power is never an option.

VERSATILITY WITHOUT LIMITS

The high-capacity 5-gallon tank provides a massive, continuous air reserve capable of blasting multiple large train horns simultaneously, operating high-draw air tools, actuating differential lockers, or managing complete air suspension systems. It offers more than enough volume to easily inflate heavy-duty truck and off-road tires up to 39”. To ensure absolute long-term reliability on the trail, the all-steel reservoir is treated with an internal anti-corrosion coating that guards against moisture and rust scaling.

READY FOR THE TRAIL

Prepared for immediate fieldwork, this powerhouse system includes the premium INF-1 tire inflation kit. Outfitted with a 24-foot heavy-duty extension hose, quick-connect couplers, and a professional-grade inflator handle featuring a luminescent glow-in-the-dark pressure gauge, a clip-lock air chuck, and an integrated pressure release valve, it makes quick, back-to-back trail tire management effortless.

Why Choose the 6450?

  • Submersible Waterproof Compressor: Fully sealed pump layout utilizes specialized internal seals, modified gaskets, and an included Snorkel Kit remote intake framework to pull clean, dry air from inside the vehicle cab during deep river crossings and severe weather. Delivers a dominant 2.1 CFM.
  • 100% Duty Cycle: Heavy-duty 200 PSI compressor is engineered for continuous, non-stop operation under maximum load without needing cooling breaks.
