MODEL 6450RC: ULTRA HEAVY-DUTY WATERPROOF 200 PSI AIR COMPRESSOR

Unparalleled Power

For over a decade, the 6450RC has remained the benchmark of Kleinn’s industry-exclusive waterproof compressor lineup. Designed as the first fully submersible heavy-duty compressor of its kind, it delivers uncompromising performance through mud, water crossings, dust, and extreme off-road conditions.

Built for Relentless Duty

Featuring a massive 100% duty cycle and producing 2.5 CFM, the 6450RC powers demanding onboard air systems, train horns, air lockers, suspension systems, and tires up to 37”. The custom heat-sink wrapped compressor head maximizes cooling while the black stainless braided PTFE-lined leader hose and heavy-duty check valve ensure reliable high-amperage restarts.

Engineered to Survive

The fully sealed waterproof design uses specialized internal seals, modified gaskets, and the included Snorkel Kit remote intake system to protect critical components from moisture and debris. Combined with thermal overload protection and a high-torque magnetic motor, the 6450RC is engineered to outperform in the harshest environments.

 

Why Choose the 6450RC?
  • 100% Duty Cycle: Built for continuous heavy-duty operation.
