Maintenance on the cooling fans of some of power modules 6SL3352-1AE41-0FA1,6SL3353-1AE41-2DA1

Dear Experts 

We have Sinamics drive system for controlling our motors inside factory , and now is the time to make some maintenance on the cooling fans of some of power modules (6SL3352-1AE41-0FA1,6SL3353-1AE41-2DA1 ) . 

I checked the name plate of the fans in both modules and the siemens product number is the same (6SL3362-0AG00-0AA1) but one of them is from ZIEHL-ABEGG and the other one I don't know , and electrical specification are different (eg .capacitance of the capacitor ).

And I need a unique product number when I want to send the request for a spare part to our store , so please help me which of the codes in the attachment picture is the cooling fans product code ?

thanks a lot
