Shop air compressor wont put out more than 110 PSI

[GARY MINKER]

NEVER Never, NeVeR use a shop compressor to air up your tires unless you have a drier of some kind in the line. Shop compressors only have one true function and that is to make wet air. The air that comes out of these monstrosities of ANY size are full of water and can really mess up the tires. Water and that powdered balancing crud don't mix either. You need a drier of some kind or Better Yet, buy a nice N or T size bottle of nitrogen and keep a 40 pounder with regulator, gauge and coily hose in the bus with you on the road. You can get it re filled at any welding shop or trade it if it is a rental. Air compressors rot the inside of the tires, promote mold growth and destroy some pressure monitoring systems. Tire shops have dehydrators on their bulk air systems. All the great things written before this post are true enough but the real deal is just don't do it unless it is an emergency. I have kept a 40 pound nitrogen bottle in the rig for 15 years. You can get 150 pounds set on the gauge any time you want because the bottle starts out between 1800 and 2500 psi. A 40 pounder will totally fill 3 tires or more. If you have your rims dismounted and the bead edges polished before remounting CLEAN tires, you will not leak an ounce and rarely use your bottled gas. --- On Mon, 9/21/09, Dorn Hetzel wrote: From: Dorn Hetzel Subject: Re: [WanderlodgeForum] Re: Shop air compressor wont put out more than 110 PSI To: WanderlodgeForum@yahoogroups.com Date: Monday, September 21, 2009, 5:33 PM When the compressor is running and then cuts off, what does the pressure gauge right at the compressor say the pressure is then? If it isn't 120+ at the tank when it cuts off then as someone else said you will need a new pressure switch (if the tank and motor can handle that pressure) or a new compressor if not.
