Durozone by DuroDyne 

Retrozone Direct Replacement Damper Motors & CAMS

  










*Please note: Current motors do not ship in original Durozone boxes although they ARE new unused motors. 

Retrozone Inc offers replacement motors for DuroZone branded motors. DuroZone motors include DuroZone 5 year warranty.


The following motors all have the same green motor case. The true difference is the red & green cam setting in each model. 

Carefully choose the model based on your damper specifications and needs.


*Please note: If you have an older style Durozone Damper RD 3 wire motor (black with five white terminals) these are direct replacements with four terminals.

Shown here is an example of an older DuroZone motor with a different style aluminum case. The new green motors may look different but are the correct replacements.
