Thomas Compressor "ULTRA HIGH" Switch Function? - hypoxia - 02-09-2025

What is the purpose of the "Ultra High" switch on the Thomas compressor select (Valid) panel?

According to the sales brochure, there is a 130-135 psi pressure setting for tire inflation.  Honestly, I've never used that switch since Newell provides an air doubler at the air chuck/hose reel in the rear of the coach.  Does your Ultra High switch make any difference?

I also noticed the low hours on your hour meter.  You've been diligent in your leak testing and very successful in eliminating them.  I've got over 900 hours between my two compressors, and I have shop air too.  Still chasing leaks and now sit at about 40 minutes between compressor cycles when parked and away from shop air.

Aha!  That's good to know.  The left hour meter quit a couple of years ago & I replaced it a week ago, it is for the Jun-Air.  I need it working to keep track of oil change times for the Jun-Air.  The right hour meter for the right side Thomas compressor is probably accurate.  I'll use the Jun-Air when occupying the coach & the Thomas when it's parked.  The compressor cycles once every couple of days when not occupied.
