text: If a diver descends to 33 feet, or 2 ATA of pressure, the air they breathe is compressed to half of its original volume.
text: The pressure during the dive from the water pressure does not cause the inert gas (i.e. nitrogen if air is used during the dive) to be compressed since it is not in a free gas state when it is in the blood during the dive.
text: Carbon dioxide scrubbing requires moisture for the absorbent material to work effectively, and moist air is undesirable for the other filter media, so carbon dioxide scrubbing is often removed by a pre-filter system before the air is compressed.
text: When the air is compressed, the partial pressure of water vapour is proportionately increased.
text: The back-pressure valve is usually set to near the working pressure of the compressor to ensure that the air is compressed sufficiently for the filters to work effectively.
text: As you squeeze the bottle (increasing pressure) the air inside the dropper is compressed, allowing room for more water to enter the dropper.
text: At a depth of 33 feet, air is already compressed to half.
text: However, the only difference is that the air has been compressed.
text: Wet bells with an air space will have the air space topped up as the bell descends and the air is compressed by increasing hydrostatic pressure.
