A scuba regulator is a device that allows the passage of air from the scuba tank to the diver. The regulator essentially connects many other gears of the scuba. A scuba regulator is comprised of three major components. These components are; first stage, second stage and alternate second stage. It is important to note that the three scuba regulator components do not work independently. In order for them to function effectively, they are connected to other devices that also perform similar functions. Together, the components help in the reduction of the pressure of the compressed air thus ensuring that the diver is able to breathe well. 

 

In the first stage the valves of the cylinder are connected directly to the first stage. The first stage receives the high pressure air from the scuba tank. In this first stage, the high pressure is reduced to intermediate pressure. What happens in this stage is that when the high pressure is reduced to intermediate pressure the air is let out through the high pressure hoses. The air is then directed to various attachments, mainly to the second stage, pressure gauge and buoyancy compensator.

 

The second stage also known as the primary regulator functions by transforming the intermediate pressure about to ambient pressure or water pressure. This pressure gets into contact with the various chambers of the second stage. The ambient pressure is then flown through the second stage's mouthpiece. However, the amount of air depends on the preference of the diver or what is commonly known as the diver's demand. For this reason, the second stage is also termed as the demand valve.

 

The second stage is also fitted with a button (purge button) that enables a diver to release water from the regulator. Most important to also note is that a regulator is fixed with an adjustable knob that makes the breathing easy. 

 

The final component, alternate second stage, also known as the octopus regulator plays a vital role just like the other components. The alternate second stage is commonly useful in case of emergencies such as when the primary regulator does not function. It is usually connected to the first stage. Its main distinguishing feature is that it has a long hose that allows is to go round. It is has also got a purge cover usually orange or yellow. The main thing is to make is more visible while under water.

 

Every diver should be able to know the various types or components of scuba regulators and how each functions to ensure their safety while under water. Visit http://www.bestscubaregulators.com if you have questions.
