Power Duster Compressor and Hose

My workspace has been getting dustier and dustier, so I have been wanting to do something about it. I've used canned air in the past, and that seems to work pretty well for clearing my electronics of dust. Unfortunately, the canned air pressure seems to rapidly decrease while it's being used, and the bottles don't last very long at all.

I started investigating the use of an air compressor for cleaning electronics, and a big concern was water condensing in the air lines and shooting onto the electronics that are being cleaned. I learned with some additional research that this problem also occurs when painting with compressed air, so there are a number of techniques for dealing with liquid in the air. Satisfied that I could deal with the water issue, I started looking for a compressor.

I settled on a DEWALT D55140 Heavy-Duty 1-Gallon 135 PSI Compressor. I selected this particular compressor because of the relatively low price and positive reviews. In particular, this model is supposed to be quieter than others, and I've had positive experiences with DeWalt tools in the past.

I also decided to buy an accessory set with a gun attachment and a 25' coil airhose. To deal with the water issue, I purchased an Air Dryer Kit. I placed one of the desiccant dryers at the compressor, and the other at the end of the hose just before the air gun. The desiccant balls turn from blue to pink as they absorb water so it's easy to see that they're working, and the state of each filter.

With this combination of compressor and accessories, I'm able to maintain 80psi bursts of dry air to knock the dust off of my electronics. It does a very, very good job of quickly knocking the dust off of my stuff, and onto the floor.

From there, I use my old Roomba to pick the dust off the floor, and move it out of my office. If you've never used a Roomba before, it's worth checking out. I have both a Scooba and a Roomba, which I run every day. They do a great job of keeping stuff clean.

The total cost for the compressor and the related parts was about $240. I'm pretty happy with the setup so far. It's definitely resulted in less dust being in my office.
