YOU LOOK LIKE YOU COULD USE SOME FRESH AIR. 

The HornAir 8OB2 fast-fill onboard air kit is not to be underestimated. With an 8 gallon HornAir air tank, you never need to worry about not having enough air to get the job done again. This air system is more than enough to run air tools or for any heavy-duty pneumatic use as well as using horns.

The powerhouse that fills the massive 8-gallon, 8-port tank is a set of dual Air Zenith OB2 air compressors. This comes together to give you a system that's capable of recovering your 8 gallon tank in a blazing 40 seconds

This package is perfect for load-leveling air springs or air suspension. Also perfect for airing up tires or any other pneumatic use. Please note that if you use horns, you will still need an air valve kit to connect the system properly. 

Unlike some other air systems, HornAir onboard air systems come with a complete wiring kit including a fuse holder. This takes out the guesswork on your end and helps ensure your system is installed correctly. Another great feature of HornAir systems is that they come with a standard 1/2in OD push-to-pull fitting. This means the horns you hook up will get all the air they need.

An increasing number of people are using this for more than just blasting horns! With a system like the 8OB2, you can also use the air supply to:

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