The Onboard Air system for those that won’t settle for anything but the best, The HornAir 5485K is a powerhouse of performance. Sporting Viair’s most heavy-duty compressor, the 5485K is our most powerful 5-gallon onboard air system. It’s equipped to handle even the biggest and loudest horns we carry easily, as well as have enough air for any other moderate pneumatic uses.

The HornAir 5485K comes equipped with a 5-gallon tank features seven ½ inch ports and one ¾ inch port, making it perfect for high flow applications and preventing bottleneck issues. 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.

At the heart of the HornAir 5485K is Viair’s 485C compressor. No longer do you have to choose between a fast fill rate or a longer duty cycle.  With a 100% duty cycle at 200 PSI and able to refill our 5-gallon tank from 165-200 PSI in just over 2 minutes, the 485C is the best of both worlds and stands out as the premier compressor to get with any of our kits. Not only is the 485C insanely powerful, but it is also the quietest compressor in its class and only pulls 28 amps!  

An increasing number of people are using this for more than just blasting horns! With a system like the Horn Air 5485K, 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 5485 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!

100% duty cycle at 200psi??? Yep SOLD!!!

First off amazing product here. Far superior than I have ever used or encountered in the past. This pump and tank are amazing together. There quality is quite impressive. The 5 gallon tank was smaller than I envisioned and the pump was way more beefier and much more well made than I was anticipating. Win win for install!!! I am a total amateur garage mechanic with basic automotive skills and this kit was a breeze to install on my 2016 Toyota Tacoma TRD Off Road, and I managed to do it alone... Well the dogs helped (slowed me down)... I have the pump mounted up under the rear bed and the tank is bolted to the spare tire structure with two Shockers Fwd and Aft of the tank. From inside the cab I cannot even hear the pump running. I literally have to come to a complete stop and roll down my windows to hear it, and it's only 7 or so feet behind me. I upgraded the pressure shut off switch and pressure relief valve to 200 psi so I can get a greater volume of air for the onboard air system I installed. Its perfect for airing up after 4x4ing through the desert. Plus the pump is 100% duty cycle at 200psi, (WHAT???) so why not let it perform. I also installed Hornblasters high flow pressure regulator for the Shocker XL's and set it to 150psi for ideal hornage. Totally awesome product here. I could not be more pleased with my purchase.
