The Blower that Blows Air

Just push the button for a blast of air…

I picked up this Air Duster (as it says on the tin, or as Amazon calls it “Compressed Air Duster, New Generation Canned Air, 33000 RPM Electric Air Can for Computer Keyboard Electronics Cleaning, 6000mAh Rechargeable Battery, Reusable Dust Destroyer”).

Right, “Reusable Dust Destroyer” is good… Anyway, I got this tip from an exhibit shop pal of mine. He said they stopped buying cans of compressed air and just got one of these instead.

Interestingly enough, I too was using cans of compressed air in my home shop, and I really don’t like buying them just to use them up and throw them away, so this thing is a good replacement. (I do not have a need in my shop for a large compressor, so a small handheld device is much preferred.)

This thing works well for my needs. I have just a few minor gripes. The first is that, at least compared to a can of compressed air, it takes a second or two to deliver a full power blast of air. The blower motor takes a bit of time to spin up to full speed. This is pretty minor, and I can live with it, but if you need immediate satisfaction of blowing air when you pull the trigger, you may be disappointed. If you can wait a few seconds, you’re all good.

It comes with two attachments, a normal nozzle and one with brush bristles. I really only use the normal one, but I guess if I want to clean out a mechanical keyboard, the bristle version could come in handy. It may also work well for cleaning dust off flat surfaces with aid of the bristles.

There is a place to store the one you are not using, but… then you can’t use the device, as it blocks the trigger!

I think the way it’s meant to be used is that you can remove and store the nozzle when you are not using it, but you can’t really keep the other one there since it acts as a trigger guard. This is probably a good solution for portability and travel.

One more way it is different from compressed air cans is that it does not get cold. If you’ve ever purposefully used a can of air to freeze something, this will not do that. If cans of air getting cold always annoyed you, this does not have that problem.

The nozzle is quite large compared to the tiny diameter “straw” that a can of compressed air has, so if you’re going into a tight space, that might make a difference. (I may experiment with 3D printing more nozzles, which should not be difficult.)

Of course you also have to charge up this one before you use it. Honestly I’m not running it that long when I use it, so I’ve probably only charged it twice since I got it four months ago. It comes with a short Micro USB cable which I probably binned because I have dozens of them around already for charging things.

So yeah, the “Reusable Dust Destroyer” has been a nice tool for the shop, and I’m pleased to not be purchasing cans of compressed air once or twice a year anymore.
