but true. Sucks cold air in through metal heat exchanger.

Unlikely to suck the air after it has been warmed, by recovering
latent heat from the heat exchanger, as this increases the necessary
fan power, more usual to blow ambient air. The salient feature is that
there are two separate circulations.

I'm sure this is all true, but I wouldn't know as I slumped forward into my
dinner and nearly asphyxiated in the mash half way through.
