You can use those to blow the bad drivers right off the road.

What kind of bus are you looking for?  Do you know how much air they take?  What size air line etc?

Yup, they'll work on 90-150 psi... but that isn't Volume! which is measured in CFM.

Good Luck!  Wink

I'll tell you...

An air starter tank would make a great reservoir to feed those monsters!

Seriously, you may want to be thinking about isolating those babies with a pressure protection valve, so the rest of the coach doesn't empty through them, if the valve should "stick open" too long.

You'd like to have enough air left to stop with!!!

happy coaching!

You'll need at least 3/4" air line to run these at all.  Below that they won't sound right, won't have much audible volume, and would be a waste of the roughly $1,000 that they are worth if new or in good working condition.

To provide enough air volume for at least a couple seconds or so of use, you will need a dedicated two gallon tank -- three to five would be better, and five would probably let you use 7/8" or 1" line as well.

The canonical way to add diesel chimes or ship's whistles to buses or trucks is to install the dedicated tank fairly close to the horns and plumb them with large diameter line, then run 3/8" standard DOT air line from your auxiliary tank or supply to the dedicated tank through a pressure-protection valve.  This last item will protect the rest of the air in your aux tank when you vent the horn tank to atmosphere through the chimes.

Bear in mind that these chimes are illegal to use in many, many states, and illegal to even have installed in quite a few (actual railroad locomotives follow a different set of laws).  The statute usually does not call out diesel chimes in particular, but is instead worded to prohibit "excessively loud" horns or horns over a certain output in dBA .  So you might think about installing them where they can not be seen by the casual observer.  FWIW.

He probably won't have enough air for a long enough blast to allow the cop to pinpoint where the sound came from  Grin

There was a nut up in the NW at a Eagle rally that had a set of these mounted on the top of his coach. I do not think he ever used them on the road. They were great for calling everyone when the chow was ready.

The little air horn on my Dina is loud enough.  I couldn't imagine the noise from that big horn. I never even knew I had an air horn for a long time.  There was a button on the floor next to the dimmer swith that I had no idea what it was for.  My friend accidently stepped on it one day and we found out what it was in a hurry.

There is only one time that the air horn has ever been used on the road.  One day it was maybe 2 am going through a tunnel on I80.  The tunnel was empty so the driver blasted the ar horn a few times to hear the echo.  My friend who was way in the back had no idea why the horn was being blasted and came running up to the front in a panic.  He thought we were going to crash or something.
