View source for Delta Fans Naming Scheme

Delta fans follow a clear 8-segment naming scheme for their fans, in 2 parts separated by a ''hyphen (-).'' Example: <u>AFB1212HE-BF00</u>

# The <u>first segment</u> consists of three alphabets, defining the '''Series Code'''. 
# The <u>second segment</u> is 2-3 digits and defines the '''dimensions''' of the fan frame.
# The <u>third segment</u> is 2 digits specifying the '''operating voltage''' of the fan.
# The <u>fourth segment</u> can be 1-2 alphabets, it describes the '''speed''' of the fan.
# The <u>fifth segment</u> is a singular alphabet, specifying the '''thickness''' of the fan frame.
# The <u>sixth segment</u> describes the '''frame type'''.
# The <u>seventh segment</u> specifies the '''signal output''' of the fan, if any.
# The <u>eight segment</u> specifies the '''signal output voltage''' of the fan
