It is activated by the light and has the usual overrun of a bathroom fan (because it uses two bathroom fans).

 

Ta. Are the fans a matched pair in terms of lpm?

Just caught up on this thread. A few posts here are a bit concerned with the conductance (thickness and/or conductivity) of the separator material. My conclusion is that typically the resistance is dominated by the boundary layer resistance so the material doesn't matter all that much: https://edavies.me.uk/2014/03/mhrv-area/ , the hard part is making the area large enough in a compact and cheap way.
