Disabling Cascade Fan's Beep
TL;DR:
- Open 11 screws.
- Remove the cap on the buzzer.
- Done.
The Cascade Personal Fan has a very loud beep. I disabled the beep by removing the cap from the buzzer. I am documenting my steps because in my quest, I saw a lot of people with the same issue.
We got a 2-pack from Costco and while the fan is very quiet, the beep is quite loud. Seems like everyone else has the same issue with this fan. All we need is a number 3 Philips screwdriver.

these buzzers and a lot of people are annoyed with the sounds. I saw guides on

The second result for searching ZLFY
is the datasheet. It appears to be a
ZLFY ZL-YDW12055-4005PA-7.5

I used a flathead screwdriver to pop the buzzer cap:
