We have a lot of these great little EC fans, 

Fully compatible with a 0-10v signal and EC commutated motor. 

So you can add your own generated 0-10v signal or work with a std potentiometer for easy and cost effective control.

These are new units - selling as the end customer went bust and we have redundant stock.
