Milwaukee is coming out with a new M18 cordless jobsite fan, featuring an 18″ fan blade size and brushless motor.

The new Milwaukee cordless fan is recommended for space cooling and ventilation, and features a reinforced metal base and shroud design for greater durability in demanding environments.

The fans can interlock and stack together horizontally for more efficient storage and transport.

Milwaukee says their new M18 cordless fan “delivers corded performance anywhere on the jobsite” and that it “quickly propels air, allowing for fast and efficient cooling, drying, or ventilation.”

I have seen cooling, ventilation, and drying fans and blowers tethered to wall outlets, and when they’re not, extension cords get strung around all over the place.

This seems like a welcome addition to the M18 cordless power tool family.

My one question was about the runtime: is it worth it?

You get 5 hours on high with a 12Ah battery, which seems pretty good, and even 9 hours on low with a 5Ah battery. Keep in mind that this is an 18″ fan. Those numbers seem decent to me.

Here’s my next big question: would One-Key connectivity make sense here?

It was maybe 4-5 years ago when a Milwaukee product manager remarked about how much their One-Key lighting products were being used with the app, with remote control and scheduling functions being popular.

Thinking about this has me wondering if and how One-Key might be useful here, especially if there are multiple fans set up at a worksite.

This is Milwaukee’s 3rd cordless fan. It will be joining their M12 mountable fan (0820) and existing M18 jobsite fan (0886), which are both recommended for personal cooling tasks.
