Before I bought my Billows, I was a big fan and user of the now discontinued BBQ Guru Party Q. Thermoworks says that the billows will work just find if you just plug it in to one of the WSM vent holes but the last time I did that it really didn't work that well. I got an uneven burn in the charcoal ring, and couldn't maintain temps. Other forum members have suggested a "dog bowl" adaptor that covers the entire vent dial, but I never could quite understand that set up.
So, I measured the inside of the guru fan adaptor, and asked T-works to give me the mating dimension of their nozzle and it seemed like it would fit so I bought it. Today's fit trial was a success. If the weather cooperates, I'll do a cook this weekend and let everyone know how it works. Here's a photo of the "fit trial" on my kitchen counter. Note, the guru adaptor is mostly for use on the WSM. I can work in a Weber Kettle too, but you have to put the right sized hole in the bottom of the kettle and make sure it won't interfere with the one-touch ash sweeper. The air diverter shown below directs the air towards the bottom of the bowl so it's more evenly distributed vs without the damper. I think this will work better but I won't know for sure until I give it a try.
The other benefit of this set up is that when you install the bellows to the WSM without the adaptors... the springs on the billows are kinda strong and can be a challenge to squeeze together and get into the damper hole. With this set up, just wipe the inside of the adaptor with a wet finger and insert the Tworks adaptor... super easy.
