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 comes complete with a remote mountable intake filter assembly, or “Air Filter Snorkel Kit”, allowing you to relocate the air filter up to 6 feet away to keep it away from moisture and debris. It also includes a standard 1/4″ NPT stainless steel braided leader hose with check valve and insulated wiring for fast installation.

My original compressor was 5 or so years old and it decided to quit working It lives a rough life underneath the truck. I got on Hornblasters website did some research and even contacted Hornblasters about some questions. i was emailed back by the end of the day and this locked in my decision. Ordered the new compressor. it was at my house in 3 days. Installed the compressor on the truck and it worked great.
Purchased the Viair 400C in stealth black to replace my old worn out Viair 400C. I swear this compressor is faster and a **** of a lot quieter than my original one.
Absolutely love these guys! I bought the Viair 400c to add to my Conductor Special,(faster fill times) Arrived in Canada three days from ordering. Even with Duty fees it was cheaper than local sources. Install was quick and simple, pics to follow. Having a blast!
