Duster

[Michael_horatio]

Over the years I don't know how many cans of compressed air I've bought for cleaning out computers.
They work fine, but poor value for what they cost and inconsistency in differing brands.

I decided to try one of these little electric battery powered air dusters. $30. I have two computers here that have been overdue for cleaning for a while now. It's not bad really. Not quite as much blast force as the canned compressed air method, but plenty good enough for the average computer cleanup with the help of the little brushes that come with it. Good enough for ordinary dust, but wouldn't work for a really serious caked on crap load of dirt.
Did both machines and still had half a charge left.

You know, I fucking HATE those cans. For the price of 3 of them, that sounds like a very good gizmo.

(and yes, crappy compressed air is both a rip off in that the cans don't last long, as well as often a sticky residue... a "bitterant" to discourage inhalation. The best compressed air cans are "Dustoff" brand)

I often thought about buying a compressor, but for a good one that won't put out condensation, or metal filings, it's a lot of money.

That might just be the ticket. You really don't need a lot of force and to get it with those cans you're usually spewing propellant. It's short quick blasts that are practical. I keep two cans, so they never get cold if I need more than the one use.

How noisy is it? Nails on chalkboard?

To me it's not that bad, but I'm half deaf anyway. It's supposed to spin at about 91000 rpm on high speed so it is definitely a bit loud. Sort of like the dentist's drill only louder. But nothing serious - not like nails on the blackboard. After I did the two machines it took about 35 or 40 minutes plugged in to a USB port on my computer to bring it back up to a full charge. Build quality seems pretty decent - doesn't feel cheap at all.

91000 rpm... I should hope it's well constructed

My first job at Bissell at their plant in my town was processing returns of vacuums and carpet cleaners etc. On the upright models, there was a motor with a thin metal disc-like fan carousel that spun at high speeds. It looked like it wasn't fastened properly and came off. The unit was systematically destroyed by this rogue fan, good thing the user wasn't hurt. Plastic was melted and cut and you could see where it went through the baffle, down into the dust chamber/housing and destroyed that, cutting right through it (again, a melted kind of cut from the friction). Wow, I was impressed

I thought that speed sounded like an exaggeration, seemed hard to believe. But looking at some of the more expensive models: they state speeds of 90,000 to 150,000 rpm on the highest speed.
But, like I said, the one I have feels quite heavy and solid.

Ya, something like that could put Bissell out of business if that fan got out.

I might look into that after I move.
