Dual Stealth Black Gen 2 485C Onboard Air System (200 PSI · 3.82 CFM · 44 Amp · 12V · 2.5 Gal. Tank)

VIAIR’s Dual 485C Onboard Air System (OBA) is our first OBA with new 485C Gen. 2 compressors that provide 100% duty cycle at 200 PSI. This pre-packaged compressed air solution includes: two Platinum or Stealth Black 485C compressors, a 2.5 gallon air tank, an inline pressure regulator, and all necessary components needed to install a working onboard air system.

The 485C features upgraded internal components that make it a true 200 PSI-rated working pressure pump, and has newly designed thicker vibration isolators that absorb vibration and sound. The modern-inspired head design highlights an eye-catching setup. This Gen. 2 Onboard Air System delivers the vital air source for numerous pneumatic applications.

Please Note: Use thread sealant for proper installation. Thread tape is not recommended. Properly sealed, recommended torque for 1/8” is 10 ~ 11 ft. lbs. Recommended torque for 1/4” and 3/8” is 16 ~ 18 ft. lbs.
