Alpha CD Fan Assembly 1.029719
This Fan is the part in the boiler that removes all the carbon monoxide produced by the boiler and it is the part that provides the oxygen to keep the burner running safely. The fan is monitored and driven via the pcb on the boiler, on the older boilers the fan is connected to an air pressure switch via heat resistant tubing which connects to the fan via venturies that are located in the fan. If the fan fails to run the boiler will be shut off by the printed circuit board making sure no carbon monoxide can be created by the burner when the fan isn't running.

The term OEM stands for "Original Equipment Manufacturer" this part is an original part and was bought from the Original manufacturer of the part.
What does that really mean?
The part was made by a company for a boiler manufacturer such as Wocester Bosch, Baxi, Glowworm etc.
Below is an example:
• Gas Valves on most British Gas Boilers are made by Honeywell, Sit, White Rogers etc. This means that these manufacturers are the OEM for the Boiler Manufacturers, so as long as the original part is purchased (Honeywell, Sit, White Rogers) from the OEM it can be sold as an original OEM product.
OEM parts are also referred to as After Market Parts.
