6450: Ultra Heavy Duty High-Capacity Onboard Air System

The Ultimate Powerhouse

Take your pneumatic capabilities to the next level with the Model 6450. This is our premier "Ultra Heavy Duty" system, designed for users who require maximum air volume and zero compromise. Featuring a massive 5-gallon air tank and a high-output, 100% duty cycle waterproof compressor, this system is built to handle the most demanding tasks without breaking a sweat.

Versatility Without Limits 


The high-capacity 5-gallon tank provides a massive reservoir of air, making it capable of much more than just firing the loudest air horns. It is the ideal source for inflating tires up to 39”, managing air suspension or lockers, inflating large rafts or sports equipment, and even operating small air tools. The tank is internally coated with a specialized anti-corrosion lining to prevent rust for years of reliable onboard air service.

Ready for the Field 

Dominate the trail and the highway alike. The 6450 includes our INF-1 premium tire inflation kit protected in a custom Kleinn canvas storage case. To match the increased output of the 6450RC compressor, this kit features a 24’ heavy-duty air hose with quick-connect fittings already attached and a professional-grade inflator with an integrated luminescent gauge, clip-lock chuck, and pressure release valve for the fastest and most accurate inflation available.

Why Choose Model 6450?

  • Industry-Leading Submersible Waterproof Compressor: Drive with total confidence through river crossings or monsoons by drawing air from inside the vehicle. This fully waterproof unit delivers a powerful 2.5 cfm flow rate for rapid recovery and high-demand pneumatic tasks.
  • 100% Duty Cycle Performance: Our elite 200PSI compressor is designed for continuous, heavy-duty operation. Featuring a stronger motor than the 6350RC, it's an absolute work-horse
  • High-Capacity Storage: The 5-gallon tank provides ample air volume to inflate tires up to 37", manage air lockers, or deliver long, loud, blasts to the most power-hungry train horns.

However, it is important to note that this warranty does not cover any damage that results from abusive use, operation that is not in line with the product’s intended purpose, or harm resulting from exposure to harsh environmental conditions. In the event that a product is found to be defective within the warranty period following a thorough inspection, Kleinn Automotive Accessories reserves the right to either repair or replace the defective item at no additional charge to the purchaser. It is our goal to ensure that our products meet the high standards that our customers expect, but we also want to clarify that Kleinn is not responsible for covering any costs related to the installation of our products, nor are we liable for any loss or damage that may occur as a result of the repair or replacement process of any product under warranty.
