Most likely the throttle valve is stuck open. On sanders usually sanding debris has coated the throttle valve pin, causing it to stick. Other times the throttle valve seal has worn and needs replacement.
If it's new, it may be too tight yet. Put a bit of oil into the air fitting and run it under no load. It may start to run faster as it wears in and the oil goes through it. After running it for several minutes, try it again and see if that works.
You need to look at the tool cfm requirements because they are posted on the package or usually in the ads. Your compressor will run the sander, just how long at a time will depend upon your tool's cfm. Rick
Normally when the air will not drive the tool, it is because 1- the tool is rusted up inside, 2- there is no lubrication of the moving parts - which can be remedied by putting something like WD40 in the inlet with the air switch open, 3- the drive parts are broken or worn out, 4- not enough air volume/pressure to run the sander.
You probably need to spray some lube as above & see if that will get it to work. Also turn the sander part by hand. Rick
