Compressed Air for Pc Cleaning

[Splodge1231]

I am looking to buy some compressed air for cleaning an old PC. How long do you think 200ml will last.

 

Thanks

Depends on how liberally you use it, but should at least for a few months (3-6 probably). I waste it a bit and use it to clean my keyboard, but if careful, it should last for a while.

Dont use compressed air to clean dust.  Use a vacuum.  Blowing air just forces the dust into places you dont want it and scatters it around.

No! Vacuums create static electricity.

That's a terrible suggestion.  It generates static electricity, and can ruin electronics.

 

I got an air compressor so I didn't have to spend tons of money on canned air.

Guess what, moving air generates static electricity.  So blowing air generates static electricity!  Blowing dirt and other stuff into the small areas of your computer is a terrrible suggestion.

That's not what causes static.  It's the metal coil in a vacuum cleaner.  You can get vacuum cleaners that don't have metal coils, and therefore don't create static electricity, but they're much more expensive and are usually fragile.

How does ESD (Electrostatic Discharge) occur?

ESD can occur in a variety of forms. One of the most common is through human contact with sensitive devices. Human touch is only sensitive on ESD levels that exceed 4,000V.

A recent investigation found the human body and its clothing capable of storing between 500V and 2,500V electrostatic during the normal workday. This is far above the level that damages circuits yet below the human perception threshold. Other sources of ESD damage to equipment include:

• Troubleshooting electronic equipment or handling of printed circuit boards without using an electrostatic wrist strap;

• Placement of synthetic materials (i.e. plastic, Styrofoam, etc.) on or near electronic equipment; and

• Rapid movement of air near electronic equipment (including using compressed air to blow dirt off printed circuit boards, circulating fans blowing on electronic equipment, or using an electronic device close to an air handling system).

In all of these scenarios, the accumulation of static charges may occur, but you may never know. Furthermore, a charged object does not necessarily have to contact the item for an ESD event to occur.

Ok, thanks, but you don't need to kill each other
