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.
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 12 ~ 15 ft. lbs.

United StatesThis thing is fast. And Quiet
United StatesThe staff is always very nice and helpful. The new compressor works great. Thanks for helping get my setup back running.
United StatesMy first train/air horn ever. I did a lot of research on my own and was very torn between companies. I looked at reviews and YouTube videos to come to my conclusion. I was very hesitant to spend the “extra” money on the more expensive option but I chose to buy quality in my mind, AND BOY I’M GLAD I DID!!! I purchased the JKU Wrango kit for my Jeep Wrangler. This kit comes with 2 horns, a 2 gallon tank and a Viair air compressor with all the wiring, tubing, and connections needed. The instructions and pictures where a little confusing at first, but after laying it all out and seeing it as I was reading it made a difference. Easy install to say the least and VERY helpful customer service! Now this is where quality comes in. My buddy bought the “other” brand and we did a comparison. HOLY ****!!!! My horns blew his out of the neighborhood. It’s so loud it’s ridiculous, I’m not even kidding! I’m so glad I went with the HornBlaster brand! I’m about to buy another one for my wife’s Jeep because she love it too!!! It’s so much fun to have and the reactions you get are priceless! If you are in the market and have even though about getting a louder horn you have to get one of these!!! Mind you, I only have 2 trumpets and they sell 5 or 6 trumpets, HOLY ****!!! It’s a win win for me and I highly recommend it!
