Altitude Air Pressure Calculator
At sea level there is a pressure equivalent to 10 meters of water pressing down on all of us all the time. This is because of the weight of the air above us in the atmosphere. When you travel up a mountain, there is less air above you in the atmosphere. A similar and maybe more obvious situation occurs in water–the deeper you go, the more you feel the pressure of the water above you.
The important effect of this decrease in air pressure is this: in a given volume of air, there are fewer molecules present. This is really just another way of saying that the pressure is lower. (This is called Boyle’s law.) The percentage of those molecules that are oxygen is exactly the same at every altitude: 20.9%. The problem is that there are fewer molecules of everything present, including oxygen.
At 0ft, the standard barometric pressure is 101 kPa (760 mmHg). This means that there is 100% of the oxygen available at sea level.
THE SAFEST, MOST EFFECTIVE OXYGENATION SYSTEMS ON THE PLANET™
Why Choose ACT
There’s a reason ACT is recognized as a global leader in oxygen control systems. Creating a mountain sleep environment that feels comparable to sea level requires far more than simply adding oxygen to a room—it takes advanced technology, careful engineering, and deep experience. When investing in an oxygenation system for your mountain home, these factors should be top priorities.
ACT has the largest residential installed base in the industry and more than 29 years of experience. Oxygen control is a complex discipline, and ACT brings unmatched expertise and a long track record of successful installations. ACT engineers developed the first normobaric (normal pressure) altitude simulation system in the mid-1990s and have continued to advance and refine the technology year after year.
