Hi Elwood,
Remove the fan assembly and look at the labels. It should indicate the
manufacturer, model, operating voltage and current. You may then go to the
manufacturer's web page or an electronic component distributor (such as
Digikey, Newark or Jameco) and order similar fans. If you want to use
substitutes make sure that the air flows (CFM ...no. of blades), voltage
(ac or dc) and power rating are the same. Pay attention to the noise
ratings as well.
It's quite a task to physically replace these fans, especially those in the
AQX rack. There are intricate soldering and wiring so be careful. Doing
this will cause significant down time of your nmr machine. If you cannot
afford this time lost, then its best to buy the whole replacement fan
assembly from Bruker.
