Air Compressors Need Clean Air Too!
The air we breathe everyday is full of contamination. It has water vapor and airborne particulates that we inhale into our lungs. The vast majority is not harmful and we barely notice that its even there. However, to your air compressor these harmless contaminants can become quite harmful due to the compression process. During the compression process an air compressor concentrates natural contaminants in the air and this process makes them harmful to air compressors and its components. Overtime they begin to erode your components, valves and be passed on to your air tools. Lets look at water condensation. Water vapor is a normal part of the air we breathe, especially if you live in a humid climate. It is harmless at normal atmospheric pressures. However when the pressure is raised in the compression process, hot air is pushed through hoses and fittings and when it contacts the cooler air condensation forms. Water can be very damaging to your air compressor and air tools over time and removing it is a priority. Water is not the only liquid that can damage your system. Even, lubrication can cause damage if excessive amounts are in your air system. Older air compressors especially have this problem. As they get older and parts begin to wear out, lubricating oils leak into the compressed air can damage the unit. Don’t forget solids too. Rust, dirt and metal are all present and will attack your compressed air system. The results of air contamination are reduced efficiency and increased maintenance costs on both your air compressor and air tools. There are several ways to attack these problems and protect your air compressor.
Aftercoolers
Aftercoolers will cool the air temperature as it is discharged from the compressor. As a general rule for every 20 degrees F cooled, approximately half of the moisture is condensed. Aftercoolers bring discharge air temperature down from 200 – 400 degrees F to within 20 -50 degrees of the ambient air temperature. This process will cause most of the moisture to condense into a liquid state. Then the water can be removed from the system before it can cause any damage. An aftercooler can generally remove around 60% of the moisture from the air.
Dryers
Dryers also remove moisture from the air compressor system by reducing temperature. Dryers generally remove around 30% of the moisture. This is in addition to the 60% the aftercooler removed. This is why you commonly see an aftercooler and a dryer both hooked up to an air compressor to produce the driest air possible.
Coalescing Filters
Now that you are removing most of the water vapor from your air compressor using a aftercooler/dryer combination, that still leaves solid particulates in your system. These are commonly rust, metal and dirt. Lets face it, an auto shop is not the cleanest environment! Filters can be added to your shop air compressor to remove these particles. Filters do not condense water vapor and are only useful for solid particles. They are not a replacement for an aftercooler or dryer.
In order to get the cleanest air possible from your air compressor, I would recommend using all three options on your shop air system. They will pay for themselves in a longer life for your air compressor, better performance and efficiency for your air tools and longer air tool life.

Is using air compressor to clean the laptop a good idea?
I’ve recently bought a hp dv6-1129tx and was just out of curiosity, thinking if it was a good idea to use air compressor to clean the bottom of my laptop in case if anything gets in the cooling area.
I’ve thought of this as my laptop at times heats up if i am processing a lot and i am not able to function normally.
That’s where I would start first if my computer was over heating.

dust is the biggest problem electronics can have. the compressor should work, but i would be careful not to force dust into areas that would not vent it. small cans of compressed air are available and would not be too excessive. try it out..sounds like fun…

Probaly a bad idea. Air compressor might be too strong. Get a can from office max and use that air. Make sure there is no dust blocking the vents. Make sure you rest labtop on a hard surface ( no beds) They even have cool packs you put under the labtop to cool it. My experience with labtops is when they overheat the video card is probaly going to go….

That would be a big N O on the air compressor idea, due to the moisture coming out of the compressor. I use one of those inexpensive laptop coolers on the bottom of mine which have fans that run while its turned on. One of these are what you need if you wanna run a laptop.

It’s an excellent idea, most computer repair shops use air compressors rather than "canned air", it’s more effective and more economical. A properly built and maintained air compressor system, (compressor,regulator, filter/water separator is capable of supplying clean, dry, regulated air. With a compressor you actually have more control than with "canned air" because you have no way of regulating the pressure coming out of the can.
As long as the temps are not excessive, the big killer for electronics is temperature differential or change, steady warm temps are fine and steady cool temps are fine but the constant changing, (causing expansion and contraction and eventually work hardening, or cracking failure) is what breaks down electronic components. This is why big industrial computer rooms are environmentally controlled.
If the over heating problem is not solved by a thorough "blowing out", consider installing a higher capacity cooling fan.

Don’t use a compressor – too much pressure, too much water, too much static electricity from the air flow. (The static electricity is why you should not use a vacuum cleaner, either.) "Canned air" is a much better choice.
