The size of the air tank needed for a horn kit from HORN KITS depends on the type of horn, the desired blast duration, and how often the horn will be used. Larger air tanks provide longer and louder horn blasts, while smaller tanks are more compact and suitable for limited-space installations.
For moderate use, a 2- to 3-gallon air tank is usually sufficient. This size allows for a few seconds of continuous horn blasts before the compressor needs to refill the tank. It’s a great option for everyday drivers who want an attention-grabbing horn without excessive air storage requirements.
For those who want extended horn blasts or higher-powered train horns, a 5- to 8-gallon tank is a better choice. These larger tanks store more compressed air, allowing for multiple long blasts before the compressor has to cycle on again. They are ideal for commercial trucks, off-road vehicles, and anyone who wants maximum sound performance.
If space is not a concern, a larger tank is always a good investment. It reduces the frequency of compressor activation, extending the compressor’s lifespan and ensuring consistent air supply. However, the installation area should be considered—bigger tanks require more mounting space, which may not be feasible for every vehicle. By selecting the right air tank size, users can achieve the perfect balance between performance and practicality.
