This is the housing I designed for a high-powered turbofan. It is compatible with 28.8mm-29mm turbofans, uses two 21700 power cells, and charges via a 2s battery charging board with battery balancing (Type-C interface, protocol: qc2.0 15w).
It supports the installation of a stepless speed control knob and features a self-locking switch slot.
Applications:

It can be fitted with nozzle extensions for dust blowing and inflation. Use it as an air circulation fan for welding, for rapid cooling of hot melt adhesive, and more.
A vacuum cleaner extension can also be installed for cleaning small areas.
Please Note:
It is best to use a turbofan with an integrated electronic speed controller. You can purchase one yourself or check out my Xianyu store (AW's shop)
Separate units can also be used but may be more difficult to assemble. If you encounter assembly problems, leave me a message, and if there are enough requests, I will modify the model for better compatibility.
Other accessories can be purchased online. I will provide a bill of materials with pictures to help you find them, most of these parts are common. (Tip: If you are worried about compatibility or find buying individual parts too much trouble, you can purchase a complete kit from me. I will list it when I have time but shipping might be delayed until mid-to-late February)

Please Note!!!

Building your own turbofan involves inherent risks and requires sufficient skills and experience. Please prioritize safety and do not attempt anything beyond your capabilities.

This is a rather rudimentary assembly guide I've published for your reference.

The turbofan in the video is the stepless speed control version without a battery level indicator. I am now using a push-button speed control version with one-touch high-speed start, three-speed settings, and a battery level indicator module (this can be installed or omitted; wiring instructions are available in my images; it's very convenient).
