Choose pressure and tank capacity
At the core of any horn system is the air source, which provides the air pressure needed to produce the loud sound. HornBlasters recommends choosing an air source that can deliver at least 110–120 PSI for maximum loudness, along with at least a 5–6 gallon air tank to ensure the horns have enough honk time. There are a variety of 110V air compressors and air systems available that can work well for this purpose.
