need help

I built this for our High School for friday night football games. I was given 2 trumpet horns, one a International Harverster, the other a Grover, also i used a mk2 kong set that is rated for 200 psi. Will the the 2 trumpet horns be okay to blow at 200 psi. My next issue is i could only fill my large tank to about 160 psi with a large shop compressor. I used the smaller tank that came with the mk2 as a volume tank. what can i do to get a constant 200 psi. im new to the forum and sure could use evryones help.

I would run them between 100-120psi. The Seige kong might be able to take it. But no the others. It will kill the diaphragms.

I have a viair 400c compressor, do you think it will fill my large tank with no problems or do i need the dual 480

It should but will take some time for those two tanks.

How do you feel about nitrogen, i could use it to blow the kongs and fill my small tank with the viair compressor for the trumpet horns.
