Replacement for Comair Rotron MD48B2

Hi, I need to replace several MD48B2 fans in a nautel transmitter. Do you have any fans that would work in this application but have upgraded performance over the original fan, as we still have overheating issues with the transmitter? Thanks.

Welcome to the community! We don’t have an option with the same footprint that would have better performance over the original fan. Also, we do carry the original fan CR074-ND,
