EVERYONE LOVES PANCAKES.

If you need an onboard air system with big capacity and power in a smaller package, you've found the right kit, the HornAir 444K is what you're looking for. Not only is the HornAir 444K great for train horns, but this constant duty system also packs enough power to meet and exceed many pneumatic needs. Our Nightmare edition comes with a stealth black finish on the Viair 444 compressor to give the system a clean and low profile look.

Included is our matching Black 4-gallon pancake tank that has four 1⁄2” ports on top, two 3⁄8″ ports on top, one 1⁄8” port on top, and one 1⁄4” port on the bottom. Strategic placement of the ports allows you to be able to install your drain cock on the bottom-most port on the tank for optimal draining no matter how the air tank is oriented. The ½ inch ports provide optimal airflow, preventing bottlenecking that occurs in other kits. This tank is great for stashing in a wheel well or other areas you need a 4 gallon tank in a tight spot. 

The stealth black Viair 444C that comes with our Horn Air 444K is a constant duty compressor that was built to handle a heavy workload. With a 100% duty cycle at 100 PSI and a recharge time from 110-150 PSI of just less than a minute, the HornAir 444K makes sure you always have the air that you need. The 444C is part of a new generation of compressors that feature a brand new, patent-pending, intercooler head design that helps disperse heat much more efficiently.

An increasing number of people are using this for more than just blasting horns! With a system like the HornAir 444K, you can also use the air supply to:

• Adjust tire pressure
• Moderate pneumatic use
• Inflate water toys and safety gear
• Supply air to load leveling bags
• Supply air for differential lockers
• Blow up kids toys
• And lots more!

While the HornAir 444K is a complete onboard air system that provides you with everything you need to get up and going, be sure to add a wireless remote, tire Inflation Kit, or an electric drain valve kit to get the most out of one of the best onboard kits you can buy!

Our HornAir systems come complete with all necessary fittings, including a Viair 110/150 Pressure Switch with a built-in relay, safety blow-off, air gauge, and drain cock. Unlike many other onboard air systems, ours comes with 10 and 18 gauge wire, as well as a complete wiring kit including a fuse holder. This takes out the guesswork and helps ensure your system is installed correctly. All of our kits are also backed by a one year manufacturer's defect warranty as well as lifetime tech support!
