Air Regulator WITH Pressure Switch for On-Board-Air set up / Air Horns & Aux Air ...

Hi Bill, I've got a Viair 150 PSI compressor, a 110-145 psi pressure switch and a 2 gallon tank with a Regulator for the air-horns. I've experimented with a few different air horn types and they all seem to "like" a specific air-pressure "range". Here's my question. Since I'm regulating only the air line to the horns down to about 90 psi - will the unregulated aux air line for filling tires provide a high (max) pressure feed since it's coming off of the tank unregulated? If I were to swap out the Pressure Switch for a 90-110 OR a 80-100, that would limit the overall pressure in the tank and actually be less air available for the aux line, correct? The ideal range for the existing horn is 80-100psi and I don't want to reduce any output from the aux line. Thanks in advance! Rick

In most applications, you want your compressor to fill to it's normal cut out pressure level. If there is a tank, this gives you a greater reservoir of pre-compressed air to draw on without having the necessity of the compressor cycling on and off constantly.

It's also not unusual to have an air regulator in every line to every different application. In this way you can limit the pressure to one application to a low level, and not interfere with the air pressure requirements of another application.

Hope this makes sense.

Cheers,

Bill
