When connected to a ThermoWorks compatible controller (required), the Billows fan quickly gets your smoker up to the target cooking temperature and keeps it there. The powerful fan maintains precise temperature control, whether you’re cooking in a stick-burner, ceramic, barrel, or drum cooker. An optional expansion connection kit is available to pair two Billows with the same controller for large smokers or cookers, but you’re not likely to need it, as powerful as Billows is.
