I bought an air compressor at an auction, just the tank and compressor, no electric motor. It is an 80 gallon tank, two stage compressor. The compressor name tag says, Dresser Model TRU-7.5, S/N 250687-07. What size electric motor do I need? Either 120 or 240 volt, and at what RPM is it supposed to run at?Thanks for any info.Mark

Unloader valve working MOST of the time, but one failure almost started a fire. Would like advice on how to determine what's wrong. Disassembled, cleaned and reassembled. Found nothing suspicious. Still doesn't unload each time as it should. Parts estimate please.

I have a LeRoi Dressor Model Q600DC air compressor and would like to try and find a service and parts manual. This fall something failed on the unit and believe it to be electrically related because now it prevents the unit from starting. I found a Q600D manual but the person told me its not the same as the Q600DC. I would appreciate any information you can give me.

I have a 1988 Leroi Serial # 3120x112Model # A219-89 I have a question?If your compressor is low on oil will that preventit from starting. The fuel is not getting to the injectorsthe fuel filter is full but its not getting to the motor.What could the problem be. Can u help me. Thanks Dave.

#Leroi Dresser by David Swaney on 2011-09-23 15:58
I have a LeRoi air compressor, serial # 3120x250. I found another # A219-89. Assembled @ Dresser Industries Inc. Sidney, Ohio. 62-48 I have a few issues with it. First issue is over heating. So I should probably install a new thermastat, but cant seem to find and purchase in my area. The second issue is, leaking at the oil cooler which is located between engine oil filter and engine. Cant seem to find a replacement part for that either. I do automatic underground sprinklers, which need to be blown out every fall to keep from freeze damage duing winter. I am in a bit of a hurry because it is my only compressor and my one thousand costumers are counting on me to blow out there sprinklers. A quick response to solve these problems is very appretiated.
We want to know if we can convert a leroi rotary compressor mod 20-25-30 SS to a vacuum rotary screw and what it needs to convert ,what does it takes and how much it costs to convert if its posible ,thanks in advance for your precious help. greetings from Mexico .
