Synchron Replacement Motor








Synchron 37944L Replacement Motor for Ztech and Buetler applications

Synchron 37944L replacement “yellow wire” left hand rotation for direct replacement Ztech Buetler motorized damper applications. If your motor carries this part number, this will be the exact replacement motor for your application. Mounts with two screws.


We also offer two Belimo retrofit kits designed to replace the 37944L. These kits are about the same cost and include a far more robust Belimo commercial grade motor in place of the old Synchron motor. Both Belimo kits carry a 5 year warranty and will far outperform the original motor. Check them out below:


Use the LMB Kit 2 (three wire upgrade) 

or TFB Kit 2 (uses the two original wires)
