but this one worked great. It produces enough air for the horns.
Just put it on our RV with our Nathan train horns, it was enough to make 3+ long tones with fast air return. Thought we might need a 5 gallon but this one did a great job. It gives off enough air for the horns, does its job.
Pros
Comes with a 480C oil-free air compressor with a maximum working pressure of 200psi.
