The reciprocating air compressor product models built at the Ingersoll Rand factory located in Campbellsville, KY (USA) have a silver decal affixed to the air receiver tank that displays identifying data applicable to that compressor. This decal is typically located near the discharge port on the tank.
Near the top of this decal (in large font) is the serial number of the compressor package.
In the image below, the serial number of this compressor is CBV381348.
Providing the correct serial number when contacting Ingersoll Rand for support will help us look up your compressor and serve you quickly.
NOTE - The serial number located on the tag affixed to the black, cast iron compressor pump is for the pump only. Ingersoll Rand does not use this serial number to identify the compressor.
