How scuba regulators work

Scuba diving regulators are designed to reduce the high-pressure air in a scuba tank to an ambient pressure that can be safely breathed by humans. Air in a fully filled scuba tank has a pressure rating of 3,000 psi or 205 bars while the respiratory tract of humans is designed for breathing air at a pressure set at 1 bar.

When you turn on the valve of your scuba tank, the high-pressure air contained inside will gush into the first stage of your regulator, which delivers air to the low-pressure ports at 250 to 300 psi (17 to 20 bars). From here, the air is led to the second stage regulator via a low-pressure hose where it’s reduced to a pressure of 15 to 20 psi (1 to 1.3 bar). It’s now breathable for humans and the air is released out of what are known as “demand valves” when the diver inhales.

A scuba regulator set will also have a low-pressure inflator hose that connects to your BCD, allowing you to inflate and deflate your vest to maintain the correct buoyancy underwater.

What is an “octopus”?

An “octopus” is an alternate air source that’s now a mandatory piece of scuba diving equipment. Some dive regulators will come with an alternative air source while others need to be bought separately. They’re normally a bright yellow color so that they’re easily distinguished underwater and can be used as a backup air source if your or your dive buddies’ regulator malfunctions.

What is the advantage of a long low pressure hose?

Regulator low pressure hoses are usually one meter in length while the “octopus” is 1.2 meters, which is fine for most recreational diving. If you’re into technical diving or plan on exploring caves, then a longer low-pressure hose can come in useful as it can be wrapped around your neck, well away from obstructions in tight spaces.

Submersible Pressure Gauges

A submersible pressure gauge displays the air content of your tank and is essential for knowing when you’re running low on air and need to begin your ascent. All scuba regulators are mounted with a submersible pressure gauge while some are also fitted with a compass and a dive computer that displays your underwater time, current and maximum depths, water temperature and surface interval times. A submersible pressure gauge is utilized with the first stage and connected via a high-pressure line, with some systems using a gauge console that offers a more accurate reading of your remaining air.

DIN vs Yoke Valves

Most scuba regulators are fitted with a Yoke valve that is screwed over the tank and is favored by most divers and dive shops for the ease of screwing in. However, you can also opt for a DIN valve, which screws directly into the tank to create a strong seal and is favored for deep and cold-water diving. A DIN valve needs to be fitted with a DIN-fitted scuba tank valve, although adapters for alternating between DIN and Yoke valves are readily available. If you’re going to be diving in both warm and cold water, opt for a DIN system and just use a Yoke valve adapter when necessary.

What type of diving will you be doing?

While most scuba regulators are designed to function at any depth, some are specifically made to respond to the high water pressure demands of deep diving. Others are designed to be used for ice diving when exposed to below freezing temperatures and are often heavier than standard regulators. If you’re doing mostly recreational diving in tropical or cool waters, then a standard regulator will do the job.

Unsealed vs Sealed Regulators

Most regulators are unsealed, which means the water can get into the first stage. These are fine if you’re diving in tropical destinations and will mostly be exposed to warm water. Sealed regulators are designed to prevent cold water from entering the first stage where it can freeze and block the air flow. They come with the addition of an environmental seal that won’t let saltwater or debris inside, making them not only more durable but also more expensive compared to unsealed regulators.

Diaphragm vs Piston

The first stage of a regulator is designed with either a diaphragm or piston construction, with the latter having less moving parts and generally considered more reliable for deep divers. However, they’re also more expensive than diaphragm models, which are perfectly safe and reliable for those diving within recreational limits.

Balanced vs Unbalanced

A balanced regulator means that it will have a consistent airflow no matter how deep you are or how much air is left in your tank. An unbalanced regulator, on the other hand, will become harder to breathe from as you descend deeper or as the level of air in your tank gets low. Most entry-level regulators are unbalanced and are cheaper to service. However, it’s worth investing in a balanced regulator as it will be much more pleasurable to dive with and avoid you laboring for breath.

Number of Ports

Most dive regulators will be equipped with at least four low-pressure ports, plus one or two high-pressure ports. Generally speaking, the more ports you have, the easier it will be to set up your scuba gear the way you want and adapt your kit as you become more experienced. If you’ve got a dive computer with a transmitter, keep in mind that you’ll need at least two high-pressure ports.

Other things to consider when buying a scuba regulator..

Comfort is key in the water, so you want to ensure that the regulator you buy is going to be as user-friendly as possible. Look for a mouthpiece that fits securely and doesn’t require you to bite down firmly (which can rapidly lead to jaw fatigue) and avoid heavy mouthpieces that are prone to falling out. Also, ensure the length of the hoses will allow you to move freely underwater and turn your head when necessary.

You want to avoid regulators that blow bubbles directly into your face on exhale, which can be annoying and reduce your visibility underwater, leading to dangerous situations. It’s also worth taking into account how noisy the regulator is when breathing, which can be distracting for some divers.

Scuba Regulator Maintenance

As scuba regulators are complex and somewhat delicate pieces of equipment, they need to be cared for and maintained if you want them to last as long as possible. When you finish your dive, always dry the dust cap by blowing on it or by releasing a shot of air from your tank, then place it firmly back on your regulator. The unit should then be rinsed in warm, freshwater and hung up to dry away from direct sunlight. Once it’s completely dry, it can then be stored away, ready for your next dive.
