Viair 400C Chrome Dual Compressor Upgrade

Looking for one of the fastest compressors you can buy? Check out the speed demon Viair 400C Air Compressor, the fastest-filling compressor in its class and the centerpiece in many of our best train horn kits. This compressor produces a stunning  2.62 CFM while pulling no more than 28 amps of power, giving you a lighting-fast recharge time. The Viair 400C can recharge a 2.5-gallon tank from 110-150 PSI in a ridiculously fast 48 seconds and recharge a 5-gallon tank in just over 1 minute and 40 seconds. With speeds this fast, this is the go-to compressor for train horns and air horns, but it also has the ability to do some light tire inflation in case of emergency. 

The Viair 400C Air Compressor comes 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 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast installation.
