I bought the things to run this horn up at 200 PSI, has anyone ran this horn at the full 200? I’ve heard good and bad things about it, but if i have to replace the diaphragms every 2 years that’s not a very big deal. So, if anyone has done this, flame on!
i run my k3 at 200 psi and ijust love them bro http://www.youtube.com/watch?v=yzl-x-6XwcY thats my k3ha and the camera isn’t good so the horns are wayy louder
It’s up to you. It doesn’t make it noticeably louder and it just screws things up in the long run. It’s your choice, some people do, some people don’t. I, personally, would never run that much pressure to any of my horns.
I like to use this example and think of it as a ratio as the prices between the two items weigh out the same… The factory intends 120-145 PSI to the horns. The manufacturer of a car puts a limit on a car’s motor for a reason (to keep it from blowing up). It might not hurt the motor right off but it will in the long run. Then you have to spend over a grand on a new motor. That’s the way I look at it on my horns. Plus, not only will it mess up the diaghragms; it can damage the nozzles too. That will cost quite a penny to get repaired… oh and here’s my ratio on prices so this analogy is justified…
Car $20,000 car motor $1,000+
Horn $400 Diaphragms and machine work $1-300
But I’m the crazy collector just looking out for people… I’ve got my flame suit on for this.
I really don’t know that much about air pressure and regulation, and I have a question. Just because your tank is filled at 200 psi does not necessarily mean that you are running 200 psi to the horn, right? I mean, I have 200 psi in the tank, but then the solenoid is only 3/8" and my air hose and air fittings are 1/2". Is there any real way to calculate what the pressure at the manifold is, or would you have to mount a gauge right on the manifold?
WTF! you dont want your horns to sound like a train’s would
right? you dont even want them to sound good either? then run them at 200 psi and fu ck what those people at micro precesion say cause they dont know s***! ok really though please run your nathan horns at 145psi tops.
sorry for the hostility i feel like im beating a dead dog though
Settle down Beavis! I just hooked mine up using the pressure switch that came with my compressors. I really don’t want to buy another pressure switch.
in short you are right. when you manipulate the volume you manipulate the pressure and thats essentially how a regulator works(though it is much more complicated than that)
ok your tank is holding air at 200 psi. that compressed air is leaving through 1/2 inch line and when you hit the horn the pressure in the line drops much quicker than the pressure in the tank and it turns into a game of catch up for the air trying to get out. As an example of varying pressures, a finger can be pressed against a wall without making any lasting impression; however, the same finger pushing a thumbtack can easily damage the wall. Although the force applied to the surface is the same, the thumbtack applies more pressure because the point concentrates that force into a smaller area. Pressure is transmitted to solid boundaries or across arbitrary sections of fluid normal to these boundaries or sections at every point. blah blah blah right? physics sucks and so does trying to understand air pressure and volume and how they coincide
^ Nice use of Wiki haha. It does explain it nicely though.
Thank you twist. wiki is the s*** and air pressure and volume are hard as hell to explain
yep, It usually solves my problems
If anyone knows of a cheap 1/2 inch regulator that doesn’t restrict the air flowroo much let me know. Or, am I going about this wrong, should I just replace the pressure switch? I really would pike the 200 psi in the tank, cause it’s a lot more air than a tank filled at 150 psi. Anyways, any ideas?
Lowes home depot if you have an account, grainger.
mc master carr has them for 70bucks.1/2" fittings.it flows 225cfm… just go to their site and search air pressure regulator
hey has it really ever damaged the k3 horns? im curious becuase im leaning towards the same setup, but with a separate battery so no stress on the engine.
Yes, it has and will. I’ve never ran 200 to my horns so I haven’t seen it firsthand, but it will. Plus a train only runs its horns at 125-140 and listen how loud it is lol 200 is NOT needed.
Ok I just bought a New set of K3LA’s.
I am running 200psi and from reading this post is sounds like i dare not do that to the Nathans…
So what pressure switch do i need something/150 ?
James
So what r u recommending ?? do u have an adjustable Pressure switch ??
\James
150 is the best. Its that simple. 200 is just over modulated. 150 vs 200 psi is also more stress on the compressors, and your electrical system. Higher air pressure means the compressor pulls more amps.
i run mine at 175 and i love it
Im gonna order a new Pressure Switch for my K3la.
currently running 200psi…
should i get the Viair 145psi
or the No Name 150 psi ???
