Where do I find serial number on my small reciprocating compressor (up to 15 HP)?

For reciprocating air compressors built at the Ingersoll Rand factory located in Campbellsville, KY (USA), look for a silver decal affixed to the air receiver tank that displays identifying data applicable to the compressor.

Here are some examples, based on date of manufacture:

• Current Serial Number Tag (Units built from 2011 – Present): the serial number begins with “CBV” and is followed by six numbers.  The serial number is located on a tag affixed to the side of the air tank:

• For units built from 2000 – 2011: the serial number consists of a ten digit numeric nomenclature and is also located on the side of the air tank:

• For units built prior to 2000: the serial number begins with “30T” and is located on a plate attached to the air compressor:

• For units with model numbers beginning with “P1” or “P1.5”: the serial number will have a different format (typically beginning with the letter “P” or “T”) and will be located on a data decal affixed to the air tank or the compressor housing cover.
