INGERSOLL RAND XP375 NO AIR DISCHARGE

IR Similar to XP375

IR Similar to XP375

HAVE A INGERSOLL RAND XP375 WIR COMPRESSOR. COMPRESSOR STARTS, LET IN WARM UP . ONCE IT WARMS UP PRESS SERVICE AIR SWITCH, GET NO AIR FROM SERVICE OUTPUT VAVLE.

Lamar, it's the engine that's warming up. The unloader valve is supposed to lower the RPM when air is being used, and interface with the throttle so that the RPM kicks up and compressed air is produced on demand.

If the engine is running, and you are not producing air, then I'm guessing it's a problem in your unloader / throttle circuit, at least based on your post.

You may need a mechanic to look at that, my friend. I can't do it from here.

I scrounged a photo of a similar tow-behind air compressor from the www.machinerytrader.com website so folks could see what we were talking about.

Cheers,

Bill

No Air
by: Ron

Hi, Ron with Air Compressor Service.

A typical problem described here can also be linked to the drive coupler from the engine to the screw compressor. These tend to break and might be a problem if no control issues are found.

I need repair/user manuals for Ingersoll Rand 100 tow behind.

Rand Air 100

Rand Air 100

The model is a Rand Air 100, and I am assuming it is 100CFM. I picked it up cheap and it definitely has some life left in it. However, it is old and has many small issues, so I can really use the manuals.

Hi Jim: I've posted your request on the "Needs a compressor manual" page. I hope a visitor recognizes your compressor and can post some info for you.

Cheers,

Bill

Hello Ian. It is impossible to be certain due to lack of any real info about the circumstances or the compressor operation.

Lack of cooling, duty cycle, ambient environment, overload of the motor due to mechanical issues... the reasons are many fold.

As a comment here, could you please provide as much info as you can about the circumstances and the conditions of compressor overheating so we can try to help you figure out what is going on?

Cheers,

Bill
