There are a lot of crazy drivers out there nowadays. Our appropriately named Safety 228H air horn kit will ensure that you get their attention and they stay out of your way when they hear the massive blast that this single trumpet horn produces. Incredibly compact and easy to install, Our Safety 228H air horn kit has been one of our best entry-level kits for years.

Have you ever been taken by surprise when a firetruck sounds its horn? That’s the same tone you're getting with our Safety 228H air horn kit. With an exceptionally punchy mid-range tone coming from this single black 25-inch bell, it’s no surprise that our Safety air horn is one of our most popular air horns

Our 228H air source unit that we paired with our Safety air horn gives you the power and performance you need in a compact and easy to install package. With the majority of the unit already pre-wired and pre-plumbed for you, installation is a breeze, making it the go-to kit for beginners or anyone with limited space. With the 2-gallon air tank, you will get 5-6 seconds of honk time with the Safety air horn. The tank-mounted Viair 280C air compressor can recover the tank from 110-145 PSI automatically in only 1 minute and 15 seconds! 

  • All-inclusive air horn solution!
  • Complete with pre-installed air valve & fittings
  • 145 PSI Air system
  • Max honk time: 5 to 6 seconds

(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. **

Big Bang for your buck

All products are made extremely well air compressor is smaller than expected compact (good thing ) and the horn it’s self is massive lol . Install probably would have been easy and only couple hours but I went all and made an enclosure with fan and vents and put terminal blocks and fuse box in bed of truck , mounted the horn to frame ran a led push button to drivers door . Horn is loud and demands attention been on for several weeks with no issues and have use frequent and have yet to hear compressor come on so tank size is plenty. Definitely recommend and have to anyone that hears it . Thanks

This horn doesn’t play around!

I was looking for a super loud horn that was different than the typical air horns and train horns you hear. After one honk of the Safety Horn I was hooked! It's violent, like stand in front of a firetruck violent. The amount of volume that comes out of this single bell is rather amazing. From 150 to 20 psi this horn absolutely rips! Amazingly efficient on air, giving you a ton of honk time. All things considered, this is my favorite horn.
