The DEWALT DCE512B 20V MAX cordless jobsite fan brings real airflow to hot garages, workshops, and job sites without hunting for an outlet. As part of the 20V MAX platform, this axial blade fan moves up to 650 CFM from a variable-speed dial, while the IP54-rated housing shrugs off dust and water splashes. It’s a practical cooling solution for contractors, DIYers, and weekend woodworkers who need a fan that can go where they go.
If you’re wondering how loud the DCE512B is, DeWalt doesn’t publish an official decibel rating, but the variable-speed dial is the key to quiet operation. On low speed, the fan settles into a background hum that works well for indoor renovations or shared spaces; when you need maximum airflow, crank it up and accept the added noise. That flexibility makes it one of the better cordless fans for noise-sensitive work.
The axial 3-blade design pushes a concentrated stream of air, and with a high-capacity 20V MAX battery you can get up to 4.5 hours of runtime at lower speeds. Battery and charger are sold separately, but the fan works with the same batteries you already own. Use it freestanding, hang it from the integrated hook, or mount it where you need airflow.
IP54 dust and water resistance means you can use the DEWALT DCE512B around sawdust, drywall dust, and light mist without coddling it. The integrated hook and stable base give you mounting flexibility, and the tool-only design keeps the price down if you’ve already got 20V MAX batteries.

The DCE512B is designed to move plenty of air without sounding like a leaf blower. While the exact dB rating isn’t published, the variable-speed dial makes it easy to drop the noise level when you need to concentrate. Low speed is a good choice for indoor renovations or shared spaces; crank it up when you’re working alone in the open and want maximum cooling.
Set it on the floor, hang it from a ladder or truss, or mount it with the integrated hook. The axial 3-blade design pushes a focused stream of air up to 650 CFM, and the IP54-rated housing stands up to dust and mists on active jobsites.
Use any DEWALT 20V MAX battery (sold separately). A high-capacity battery can deliver up to 4.5 hours of runtime on lower speeds, which is enough for a full morning of work. When the battery runs low, swap in a spare and keep going.
DeWalt doesn’t publish an official decibel rating, but the variable-speed dial lets you run the fan on low for noticeably quieter operation. Low speed is suitable for indoor or enclosed workspaces where noise matters.
There is no official dB rating published by DeWalt for the DCE512B. The fan’s noise output changes with speed setting; lower speed means lower noise and less airflow.
Runtime depends on the 20V MAX battery and the speed setting. With a high-capacity battery, expect up to 4.5 hours on lower speeds; a compact battery or max speed will reduce that time.
Yes. The integrated hanging hook and stable base allow freestanding use, hanging from a ladder or truss, and mounting in various positions.









Blows hard.
Great fan for the garage. It's portable and moves a lot of air.
I've worked in hot attics all summer, and this fan has been a lifesaver. The 650 CFM is no joke—it really cools down a space. I love that it can stand, hang, or mount, which gives me flexibility. The IP54 rating means it can handle dust and splashes. Battery life is reasonable if you use a large battery. The variable speed is a nice touch. Definitely worth the money.
This fan is awesome! I use it in my workshop. It's quiet enough to not annoy me.
Works as expected.
I bought this for my husband's birthday and he uses it every day in his woodshop. He loves that it's cordless so he can move it anywhere. The airflow is strong and adjustable, which he says is perfect for drying glue or cooling off. The hook is also handy for hanging it from the ceiling. It's a bit heavy, but it's built well. Great buy overall.
Good fan. Moves plenty of air. Built to last.
My son loves it.
This fan is a beast. Cools my shed fast. Battery drains quicker than I'd like though.
I was skeptical about a battery-powered fan, but this one performs like a corded model. On high, it really pushes air, and the sound is not too loud. I like the IP54 rating since I use it outdoors. The hang feature is perfect for camping. It's not the cheapest, but the quality is there. I'd recommend it to anyone needing portable airflow.
Strong and quiet.
Nice fan. I use it in the garage. It doesn't take up much space.
I was so excited about this fan but it died on me.
This fan has saved me during summer classes on campus. I can clip it to my desk, and it's powerful enough to keep me cool. The battery lasts about two hours on high, which is enough for a study session. It's also not too heavy to carry in my backpack. The only issue is the price, but it's a DEWALT, so you pay for the brand. Still, no regrets.
Really moves air.
