The VIAIR 480C Stealth Black is the premium 12V piston compressor in the VIAIR lineup. It stands out from the 444C with its increased airflow of 1.86 CFM and especially its main 3/8" stainless steel fitting with integrated check valves — a larger diameter that reduces pressure loss and improves fill time on large tanks. With a 100% duty cycle at 100 PSI and a maximum pressure of 200 PSI, it’s built for the most demanding setups.

• ⚡
  The compressor must only operate with a 40A fuse — higher or lower amperage is not allowed. In multi-compressor setups, each unit must have its own fuse.
• 💧
  Install only in an area protected from water and heat — the compressor is not designed for direct exposure to splashes or extreme temperatures.
• 🛢️
  No lubrication oil needed — the VIAIR 480C is a dry rotor compressor, requiring no periodic maintenance.
• 🔋
  Use only with a battery in good condition and fully charged — low voltage can damage the compressor coil at startup (high starting current).
• 🔩
  Make sure of a secure mounting and good ground cable conductivity between the compressor and the vehicle body.
• 🌬️
  Ensure sufficient fresh air supply — never place the compressor in a completely enclosed space.
