What is a regulator in scuba diving?
by
A scuba diving regulator is the hub of your dive equipment, and links many pieces of gear – your scuba tank to your BCD, submersible pressure gauge (SPG), alternate air source and you. You’ll always remember your first breath underwater using a regulator – it’s thrilling.
An alternate air source is an additional second stage regulator (mouthpiece) which provides a means for a second person to breathe air from your scuba cylinder supply. This is used in situations where a divers regulator may have failed, allowing that diver to share the air carried in his buddy’s cylinder.
How much does a scuba regulator cost?
Scuba regulator costs will range between $200 to more than $2000. The majority of first and second stage setups will cost around $500-$700. On the higher end regulators will be built out of titanium. Other features to expect on higher end models will be venturi controls, lighter weight, and smaller size.

What scuba regulator do Navy seals use?
The LAR V Draeger rebreather, designated as the MK 25, is a closed circuit SCUBA device. Running on 100% oxygen, all expelled breath is recycled into the closed circuit where it is filtered for carbon-dioxide.
How long does a scuba regulator last?

Should you store scuba tanks full or empty?
Never Store Your Scuba Cylinder Empty
Your scuba cylinder should always be stored with a minimum of 200 psi inside of it. If it is stored completely empty, the absence of pressure inside the cylinder can allow all sorts of things to enter into it.
How long can you leave air in a SCUBA tank?
Do not store tanks that are full of air for prolonged periods of time (no more than 3 months. A tank should be stored with just enough pressure (200 psi) to keep moisture out. Remember the higher the tank pressure, the greater the corrosion that may form inside.
Can you leave scuba tanks in car overnight?
Heat will cause the breathing gas inside the tank to expand, increasing the pressure. It’s recommended that the tanks are in a compartment with open air circulation. Tanks should not be stored in a car during hot weather or any time there is a possibility of excessive temperatures where the tanks are stored.
What is the most important feature to consider when selecting a regulator?
The most important consideration in choosing a regulator is ease of breathing.
What should I look for in a regulator?
How do you size a regulator?
Use the formula: 0.33 x A1 x P1 = Q1 (does not apply to regulators with filters). A1 = seat orfice area in mm² P1 = inletpressure in bar (a) Q1 = max. flow of air in Nm³/hour through the seat orifice area.
Which is better piston or diaphragm regulator?
A diaphragm-based regulator is a simpler mechanism and provides much more accuracy in controlling outlet pressure than a piston-based regulator. On the other hand, a piston-based regulator is tougher and has a higher resistance to damage as diaphragms are more susceptible to rupture.
What are the disadvantages of a diaphragm pump?
Cons of the Diaphragm Metering Pump:
They don’t handle off-gassing chemicals well; gas-locking of head can occur.
Large pumps can experience high pulsation which can cause piping/system damage without pulsation dampeners.
Why do diaphragm pumps fail?
Diaphragm rupture: Causes of a failed or ruptured diaphragm include overuse, abrasion, chemical attack or overpressure to name a few. A rupture means fluid will leak into the air valve and leak through the pump’s muffler.
Are all regulators the same?
Are All Gas Grill Regulators the Same? Every propane gas grill uses an LP regulator, but not all regulators are created equal. Though the purpose is the same, different types of setups require different types of regulators. The type of regulator a grill needs is based on the specific propane application requirements.
What are the 2 types of regulators?
There are two main types of voltage regulators: linear and switching. Both types regulate a system’s voltage, but linear regulators operate with low efficiency and switching regulators operate with high efficiency.
