Designed for anyone that wants their air and wants it now, the HornAir 440 brings you a complete 150 PSI onboard air system with the fastest filling compressor in its class. A staple in many of our train horn kits, the HornAir 440 is perfect for horns or emergency air inflation applications where you need a fast refill rate.  

Included is our 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.

Powering our HornAir 440 is Viair’s speed demon of a compressor, the ViAir 400C. As one of the fastest compressors in its class, the ViAir 400C can fill our 4-gallon tank in as fast as 1 minute & 45 seconds while only pulling 28 amps!

The HornAir 440 is great for light pneumatic applications such as emergency tire inflation or load-leveling air springs and makes a perfect match with many of our train horns. With such a fast-fill time, it means being able to blast your horns more often in quicker succession!  With it being a separate tank and compressor unit it is fully sealed and able to be mounted outside exposed to the elements.

While the Horn Air 440 is a complete onboard air system that provides you with everything you need to get up and going, be sure to add on 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 year manufacturer's warranty as well as lifetime tech support!

     Please Note: This HornAir system is not recommended for AirChime horns. We recommend using at least a 4-gallon tank with larger-scale train horns like the P3, P5, K3, and K5; however, this kit is perfect for HornBlasters Shocker horns and Outlaw and Bandit series horns.
