We have it (since 2004, actually -- has it been that long?!) and it works fine with our American Range (relatively high btus). I really love it. Only problem is that the lights burn out too fast. But otherwise it does what it's supposed to and only gets a bit loud when it's going full blast. Which I use only when I'm grilling hamburgers. We just enclosed the vent pipe in a cabinet, no problem.

We had the Zephyr Whirlwind in our last house. It is a lesser model than the Cyclone (fewer CFM, higher sone rating, so a little louder, and no halogen lighting)...But we found it to perform well, it seemed very quiet to us, and was easy to clean. I wouldn't hesitate to recommend it, and it seems the Cyclone should be even better.

Thank you flyleft and rhome. I was going to get the Broan Allure III but read too many negative comments about it. I like the looks of the cyclone but it has to function well.

We have the Zephyr Typhoon and I can highly recommend it.

I have the Zephyr Breeze. It looks good and is pretty quiet.Haven't used it much, though. I don't know what the difference is vs, the Cyclone, but it was cheaper and doesn;t have the black panel on the outside like in your picture. I think it comes in a couple of different power levels.

We have the Zephyr Hurricane and I would strongly recommend it. Quiet and powerful.

We just installed Zephyr Hurricane and we find it loud. We think there might be something wrong with it, as there is not much difference in the noise level between the 3 speeds. How is yours? Is there a big difference between speed 1 and 3? Also it sounds a little loud at the lowest setting (1).

We have the Zephyr typhoon 36" over a Viking 36" AG range for about 2.5 yrs - It rates up to 850CFM's at highest speeds, sleek, easy to clean & has dimable halogen lighting - at the highest speeds it is not quiet - But...having said that I use highest speeds for very short bursts during cooking process so I don't find it an issue.
