A fan favorite, our Shart 127H Air Horn Kit is a simple, compact Air Horn Kit that brings enough thunder to make you rumble down under. Our Shart 127H Air Horn Kit is loud, low and nasty. If you are looking for a deeper tone than your average air horn, but don’t have the space or budget for full-fledged train horns, our Shart 127H Air Horn Kit is a great alternative.

 As a single-bell horn two feet in length, our Shart Air Horn is has a much deeper tone that you typically would find in an air horn. Ever since we let our customers name this horn, people have asked if the name describes the tone of the horn or the effect it has on people within earshot. One thing is for sure, you can’t set off this horn without feeling a little bit dirty! 

Our HornAir 127H Air Source Unit that we paired with our Shart Air Horn with is the perfect match. Just like our Shart Air Horn is designed to be simple and easy to install, our HornAir 127H comes with most of the kit already pre-wired and pre-plumbed, making set-up much faster than larger horn kits. Even though the Shart 127H Air Horn Kit is a compact kit, you still get all the power and performance you could need. Our 1.5-gallon tank supplies enough air to Shart for up to 4 seconds and the tank-mounted Viair 275C Air Compressor recharges the tank from 110-145 PSI in a stunning 35 seconds!   

As with all HornBlasters kits, our Shart  Air Horn Kit comes complete with all required components and detailed instructions.

(Note: Tank mounted air compressors are not fully sealed. For this reason, the manufacturer recommends the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc...)
