Shart 127H Air Horn Kit

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

 As a single-bell horn two feet in length, our Shart air horn is has a much deeper tone than 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 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 is a compact kit, you still get all the power and performance you could need. Our 1.5-gallon tank supplies enough air for up to 4 seconds of honk time and the tank-mounted Viair 275C air compressor recovers 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... Failure to mount this product as directed will void the warranty)

**Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models. **
