I need a small extractor fan with decent closure of the shutters when it's
switched off. We have a "Greenwood Airvac" in our bathroom which is fine
when extracting, but allows a small gale back through the back-draught
flaps when closed.

A couple of the ones in the Screwfix catalogue mention "thermoelectric"
shutter actuators. What's that all about, then?


Have a look at the Vent Axia Lowatt range

I think that these will do what you want.

Thanks muchly.


You're welcome. I didn't look at pricing on these particularly, but
I have one of Vent Axia's other 100mm fans for the cloakroom and it
has run faultlessly for many years.

I also have two of their large axial 150mm duct fans for supplying
cooling air from outside to my comms and server equipment. These run
using speed controllers with thermistors to provide a basic
temperature control. The fans themselves are very solidly made and
run from 20% to full speed.

Certainly you will find cheaper fans, but to be honest, this is the
kind of product that I want to fit and forget about for at least 10
years.

So far I haven't been disappointed with their products.
