3-Liter Air Source Kit


Suggested Addons

The HornBlasters 3-Liter Air Source Kit, the most cost-effective all-in-one 110 PSI solution for powering your air horns and train horns! This self-contained unit provides you with everything you need to have safe and reliable onboard air. Installation is incredibly easy, as our 3-Liter Air Source Kit comes pre-wired and pre-plumbed with a built-in compressor, pressure switch, gauge, and a 1/4" compression fitting. 

Our pre-installed pressure switch will automatically activate your compressor when your air pressure drops below 85 PSI and automatically shut your compressor off when it reaches the optimal pressure of 110 PSI. This allows you to use your system worry-free without having to monitor your Air Source!

Featuring a fast fill time, our 3-Liter Air Source Kit refills quickly and automatically when you are low on pressure, ready to blast your HornBlaster horns again in no time! This is perfect for light-duty systems where you just want the air for emergencies and don't need a large, high-pressure reserve. 

**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**
