For those that need an onboard air system that that offers insane reliability, the Horn Air 248 is one of the best complete onboard air kits available. Not only is it amazing when paired with one of our train horns, but the Horn Air 248 can also handle just about any pneumatic task you throw at it. With a quick refill time and a constant duty cycle, you can be confident that you will have an onboard air system you can depend on.

Included is our Black 2-gallon Tank that has four 1⁄4 in ports and two 1⁄2 in ports. 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.

The Viair 480C that comes with our Horn Air 248 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 only 40-50 seconds, the Horn Air 248 will ensure you have the air you need when you need it.

An increasing number of people are using this for more than just blasting horns! With a system like the Horn Air 248, 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 Horn Air 248 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.
