One of the highest performing compressors that we carry, the Viair 485C Air Compressor is the compressor of choice for all of our top-of-the-line train horn kits and onboard air systems. That’s because the Viair 485C is the perfect marriage of performance and speed. The first compressor in its class to boast a duty cycle of 100% all the way up to 200 PSI, the Viair 485C can handle most pneumatic tasks you can throw at it, such as tire inflation, running air tools, powering suspension systems and powering the biggest and loudest horns we carry! Due to the Viair 485C sleek new head design, it doesn't need to sacrifice performance for speed, rocking recharge times of a fast-fill, while still giving you the constant duty dependability you need. The Viair 485C will recharge a 2.5-gallon tank from 165-200 PSI in just 1 minute and 15 seconds and recharge a 5-gallon tank from 165-200 PSI in just under two and a half minutes.

The Viair 485C Air Compressor will come complete with a remote mountable intake filter assembly, or “Air Snorkel Kit”, allowing the air intake to be moved to use clean air even if the compressors are mounted in the way of debris, moisture, and other air system contaminants. Includes a standard 3/8″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast installation.
