Billows is an automatic BBQ control fan that keeps your smoker at a steady target temperature — without constant vent adjustments or fire tending. Paired with a compatible ThermoWorks controller (RFX GATEWAY™, Signals™, Smoke X™, and ThermaQ® 2), Billows regulates airflow into your smoker, increasing or reducing oxygen as needed to maintain consistent heat throughout long cooks.

Once connected, Billows takes over the hard part of low-and-slow cooking. It brings your smoker up to temperature quickly, stabilizes heat with minimal overshoot, and helps recover faster after opening the lid. That control translates to fewer flare-ups and more consistent results over long cooks, whether you’re smoking brisket overnight or running a long weekend rib cook.
