Blowing Off Computer Equipment

Can you use your air compressor compressed air for blowing off computer equipment? Far as I'm concerned, you sure can!

When I go to the computer supply store and see that it costs $9.00 or more for one small can of compressed gas for blowing off computer equipment, I am astonished.

I've had a number of questions about using compressed air for this purpose, cleaning keyboards etc. with a jet of compressed air from a blow gun.

Another one from Fred, prompted me to write this page.

" I was hoping that you could give me some advice regarding an air compressor and filter.

In an effort to look at ways to reduce expenses & cut down on waste, my department is considering purchasing a small air compressor to replace the 80-90 cans of air we purchase each year at a cost of approximately $500.

The machines we utilize in this department are high-speed mail openers. We use the canned air to remove the dust from the sensors, and paper debris that accumulates in the tracks of the machine.

Before proceeding, I ran the idea by our technician who service our transports, and he advised against it because the "unfiltered" compressed air contains harmful particles and moisture that will damage sensitive electronic equipment.

The amount of compressed air we use on a daily basis is minimal. We use it first thing in the morning to clean the few machines we have, and we won't use it again that day unless we have a problem with something jamming.

My original thought was that a 6-10 gallon compressor would be more than enough. Chances are we would only have to charge it up once each morning, and that would give us enough of compressed air for the day. I knew there were filters available for these, but I'm not familiar with them.

When I was looking at an initial, one-time, investment of a few hundred dollars for a compressor & retractable hose, I wasn't considering a filter system (or the replacement filters that would be necessary).

It would be great if we could save a few dollars a year, and be environmentally friendly by not dumping nearly 100 empty cans of air into the trash, but this could easily lead to something that just isn't cost effective."


An excellent question Fred, and I do appreciate the detail to enable me to write a response... right here.
