PCP Compressor - What Is The Correct Pressure Of Air?
PCP Compressor - What Is The Correct Pressure Of Air?
If you are reading this article then you probably already know what PCP Compressor are, so now we move onto the reviews. The reason I mention this is that 'air pressure' is a big issue for PCP users, and in some cases Scuba divers, even PCP shooters. Well there is a simple reason behind this, well PCP compressors are forced to suck in air while using them, because of this we suffer with 'air pressure'wind resistance'. In my opinion air pressure is caused by a number of factors.
Well if you are reading this article now assume that you know what PCP compressors are, so now we move onto PCP reviews. The first thing I noticed when doing a few PCP reviews was that many people said they were suffering from 'pressure' on their decompression tank, this would of course lead to questions about what air pressure I should be looking at. Well, the simple explanation is 'Air Pressure'.
Most PCP compressors will have an 'Air' gauge which tells you what air pressure you have left in your tank. It's a useful thing to have but is not a good sign of the pressure in the tank because it doesn't tell how full you are; it only tells you the amount of air that was sucked in during the decompression process. Also it can take time to fill the tank completely so this can make it difficult to judge the correct pressure at times.
So to recap what I did for PCP users - I set a target to find the maximum amount of air to be pulled out of the tank, in other words find the maximum amount of air per minute (APM) when pushing air through the hose. This then gives me an idea of the pressure that I need to pump into the tank, it's a very simple system but it makes it much easier to judge the correct pressure. In this way PCP users can determine the right amount of pressure to use for a specific dive.
Some PCP users also claim that they don't suffer from pressure at all, in other words they have more air than they needed, but they don't need to pump more air into the tank. This is another area where more reviews would be useful, as it means I could take more air into the tank. and it will help to keep me from suffering from air pressure problems.
So I hope this helps clear up some questions that you might have had about how much air to expect to take into a PCP compressor and whether you can get it right, I hope you have learned something. Now the best advice I can give is that the most important thing to do is just trust your instinct and do some research if you have any doubt. Once you have the hang of things though you will be able to get accurate readings from your PCP compressor.
