Milwaukee has announced a new M12 cordless fan, model 0820-20.
The new fan, which Milwaukee officially describes as the M12 Mounting Fan, is said to be the highest performing 12V jobsite fan.
Milwaukee says the 0820-20 cordless fan delivers 18V-class air speed, and is a compact cooling solution [that] can adapt to various situations with the durability to withstand jobsite conditions.

As the Mounting Fan name implies, there are quite a few different ways for the fan to be mounted to jobsite structures and surfaces.

The fan features multiple mounting methods:
- Keyholes (for use with screws)
- Pass-through holes
- Spring-loaded clamp with 2″ capacity
- Magnets

The fan can be fixed to horizontal or vertically-oriented 2x dimensional lumber studs and beams.

It can also be magnetically mounted to flat ferromagnetic surfaces, such as steel electrical panels.

But, it also looks to be strong enough to be mounted to vertical ferromagnetic surfaces as well, such as iron or steel pipes.
The fan features 3 speed settings, and it can be aimed a full 360° for convenient aiming.

Discussion
Here is what Milwaukee Tool’s product manager is quoted as saying about the new fan in press materials:
With the combination of air performance and multiple mounting solutions, the M12 Mounting Fan delivers performance comparable to other 18V jobsite fans with more versatility.
I’m a little skeptical about how a smaller 12V-class cordless can could compare to 18V-class fans. So, let’s do a quick comparison.
M12 Fan: 14 MPH max, 400 CFM max
Milwaukee’s M18 cordless fan is said to deliver 18 MPH max speed and 284 CFM max airflow. The newest Dewalt 20V Max cordless fan delivers 650 CFM max, and it doesn’t have published speed specs.
A lot of other brands’ 18V-class cordless fans don’t have published speed or airflow specs.
Based on the images and dimensional specs, the new Milwaukee M12 cordless fan is likely best considered as a personal cooling fan. That’s not a bad thing, and is how most cordless fans are intended to be used.
The versatile mounting options increases the chances you’ll be able to position the fan closer to where you’re working, which will improve its effectiveness.
Its compact size might also increase its portability.
