How Do Scuba Diving Regulators Work?

Video Transcript

"Hi my name is Valerie Kervorkian, and I am with Tarpoon Lagoon Dive Center, Miami Beach, Florida. Let's talk about how a dive regulator actually works. What is a dive regulator? It is an air delivery system that delivers air from the tank to the scuba diver on a demand principle. The diver inhales, air is delivered to the diver. Air is regulated from the first stage of the dive regulator. The first stage of the regulators main function is to break down the high pressure working, the high working pressure in the tank to a more breathable pressure for the diver. The air goes into the first stage on demand, flows through the low pressure hose, and into the mouthpiece called the second stage. The air is delivered through the second stage at the ambient pressure to the diver. A dive regulator works on demand. Air is delivered to the diver when he requests it. A free flowing regulator would indicate that there is a problem with the regulator, something is wrong, and it should be service immediately from your professional dive center. Because a dive regulator is a life support system it is important that it is serviced frequently. Annually is good enough, and even if you don't want it have it fully serviced an annual check up at your dive center is important. Keep your regulator working properly."
