Water. This owns every compressed air user nuts !!! Every time they utilize an air tool, blow-off weapon, and even fill the inflatable blow-up mattress, water appears together with the compressed air.

The water is an issue if the compressed air is moving through a tool that can rust or be adversely impacted by air-borne particles, and, offered enough ' fill-ups and clears ' a considerable quantity of water will appear in anything which you run or pump up With compressed air.

Why?

Well, we understand that relative humidity is the step of water wetness in the air revealed as a portion. At a relative humidity of 90% for instance (sticky and truly hot) the environment is holding 90% of the overall quantity of water vapor it can hold. When the relative humidity in the air surpasses 100%, it generally rains.

That, regrettably, appears to take place primarily on weekends!:–RRB-

Now, let ' s take a few of that environment with it ' s 90% relative humidity and compress it. Exactly what do we desire the last atmospheric pressure to be; 30 PSI, potentially 45 Pounds per Square Inch? We will utilize 45 PSI as an example.

Free air, the environment we breathe, has a typical PSI of 14.7 (or 15 PSI to make it simpler mathematics). We ' re going to take complimentary air at 15 PSI and make it 45 PSI by compressing it. We will take 3 cubic feet of air at 15 PSI, and pack all 3 into the area of one to make one cubic foot of compressed air, now at 45 PSI.

If the relative in the environment humidity is 90%, and we are packing 3 cubic feet of environment into one cubic foot, then the relative humidity of the compressed air will nearly right away surpass 100%. As an outcome, as long as the relative humidity of the air in the compressor tank is over 100%, it will drizzle in your compressor ' s receiver. That water will collect on the bottom of the receiver, and will definitely fill it without it ' s drained pipes.

Then, each time compressed air is drawn from the compressor tank to your application, complimentary water will follow it down your lines to your air tools, your work environment, your blow-up mattress and so on

To make matters worse, compressing air produces heat. Air that would generally be prepared and not have the ability to hold anymore water vapor at one temperature level, can really hold more than 100% humidity when it gets hotter. When the air inside the tank is hot, the compressed air that is draining of your compressor tank has a greater than typical humidity level.

What takes place to air as it streams? It cools! Exactly what takes place to the water vapor in the air as the air cools? It covers (condenses) back into complimentary water.

More water!

The water created by your air compressor, together with the water vapor brought along in the compressed air itself, both add to the water issue for the compressed air user.

And that ' s why you have water with the compressed air, streaming from your air line each time you open the air line valve.
