When connected to a ThermoWorks compatible controller, like Signals (required), the Billows fan quickly gets your smoker up to the target cooking temperature and keeps it there allowing you to go on with your life while you monitor both your smoker and meat temperatures remotely through the ThermoWorks BBQ App. The powerful 46 CFM 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.

Kamado Mounting Plates (sold separately) may be used to attach Billows to certain types of smokers. See the Question and Answers section below for more details.
