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 2.1 CFM, the 6450RC powers demanding onboard air systems, train horns, air lockers, suspension systems, and tires up to 39”. 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 without needing cooling breaks.
  • Fully Submersible: Waterproof sealed compressor housing survives mud, river crossings, and intense monsoons.
  • 2.1 CFM Output: Delivers rapid tank recovery times and efficient, high-volume off-road tire inflation.
  • Snorkel Intake System: Uses a remote filter relocation line to pull clean, dry air directly from inside the vehicle cab.
  • Premium Construction: Outfitted with a durable black stainless braided PTFE-lined leader hose and heavy-duty inline check valve.
  • Compact Powerhouse: Provides the exact same rugged performance DNA as our flagship 6650RC compressor but inside a tighter footprint.

THE VERDICT: The ultimate high-pressure, continuous-duty anchor for modular air architectures. The 6450RC represents the definitive choice for trucks, utility service rigs, and off-road builds that require unbreakable waterproof reliability and non-stop operational performance.

IDEAL APPLICATIONS

  • Onboard Air Systems: Provides optimal support for high-capacity air reservoirs up to 7 gallons.
  • Off-Road Tire Inflation: Offers robust high-pressure lung power to safely air up large tires up to 39”.
  • Train Horn Systems: Serves as a perfect replacement compressor for standalone 6450 / 6450-SLIM hardware or full HK9, HK9-Slimline, and vehicle-specific packages ending in -734.
  • Air Suspension & Lockers: Supplies instant, consistent high-pressure pneumatic delivery to air bags and lock systems on demand.
  • Commercial & Extreme Off-Road: Engineered to thrive in environments with heavy debris, severe moisture, and nonstop, grueling duty demands.

WHAT'S IN THE BOX?

  • (1) Waterproof Air Compressor: 100% continuous duty, fully submersible 200 PSI pump unit
  • Mounting Fasteners: Complete set of high-strength M5 bolts, nuts, flat washers, and split lock washers
  • Filter Housing: Remote-mountable filter cover assembly with pre-installed element and secure attachment clip
  • Spare Filter Elements: (2) Additional replacement air filter elements for long-term maintenance cycles
  • Snorkel Relocation Kit: 12-foot length of 3/8” intake airline for protective routing away from trail water
  • Model 30202 Leader Hose: Premium black stainless steel braided PTFE-lined hose featuring an integrated check valve
  • Ground Connector: Pre-fit terminal eyelet for clean structural chassis grounding paths
  • Identification Marking: Official product barcode label verifying your accurate Kleinn factory serial part number
