Diving equipment – which is a regulator?

One of the key elements of the diving equipment for a scuba diver is a regulator, but everything is a regulator?

Everything starts with the air in the tank and you'll breathe underwater. To enable you to have enough air to stay down for one hour or more (sometimes exact depth depends on the depth and your personal air consumption) of the air in the tank is pressurized to squeeze Lots in. The working pressure in steel tanks is @ 2400psi tanks and aluminum @ 3000PSI.

The first function of a regulator is to reduce the pressure to ambient pressure you are under water, over a predetermined amount so that you can breathe. This is via a brass pieces, chrome and often called "first stage". It is also the piece of equipment that you attach your other air Equipment related to eg inflation BCD and gauges.

The piece of equipment you put in your mouth is called the "second step, which completes the process of reducing the pressure to ambient pressure. As long as you keep the regulator in your mouth and inhale air feeds you. The second stage of work through what is known as a regulator of the request "A" and simply by inhaling lever moves inside the mouthpiece and allows the air along the pipe the first step attached to the tank and the mouth. Respiratory arrest (never be under water) or breathing causes the lever to shut down and stop the flow of air.

When exhale lever closes, air is prevented from entering the mouthpiece and exhaled air is vented out of one side regulator.

Diving and recommends the most modern training organizations such as PADI insist that, for security reasons you also attach a second regulator to your tank so that a diving buddy can breathe tank should enough air or improper operation of equipment. Details may be different for technical or commercial diving.

Since this equipment allows the diver to breathe under the water safely, it is often the first piece equipment that divers will be recommended to buy all your life literally depends on the security of this piece of equipment. Your dive center will be able to recommend manufacturers of good quality and set up the equipment for you.
