Air Horn Application

by Colin

We are a weather notification company and use direct drive truck air horn kits for our audible siren component of our system. We want to increase sound and decrease compressors, but DO NOT want to use tanks.

We are currently using a direct drive air horn kit made by Kleinn (

We only get about 23 psi from each compressor and ideally would like to power about 4 horns (utilizing splitters) using only 1 compressors.

We found the Firestone RideRite Lite Duty compressor (, but it doesn't seem to put out as much air as the factory compressors we are using.

Do you have any thoughts on how to solve this issue?

More clarity

So, is this a mobile system where you are more or less limited to a 12V system, or is it such that 120V could be used?

If you are limited to 12V, how much current can be suppled, for how long?

How long do the horns need to operate? (I notice one compressor has a 9% duty cycle - meaning it could damage itself in maybe a minute or two)

You can get high output 12 VDC air compressors if you are willing to spend $1500 + for them.

If the budget allows, Google high volume 12 VDC compressors and you will find sources.

Yes we are using a 12v power supply

Compressor and horn
by: Bill

You don't specifically say. Are you limited to a 12 or 24 VDC power supply for the air compressor to drive your air horns?

The logical solution is to use a larger compressor with higher pressure and flow, but if your power supply is limited, so too will the compressor size.
