A 1st stage regulator is a mechanical device that attaches to the scuba tank. It reduces the air pressure from the tank to an intermediate pressure. This intermediate pressure then moves to the second stage regulator. This further reduces the pressure to a level that is safe for breathing.

The 1st stage regulator also has a high-pressure port. This allows for the attachment of a submersible pressure gauge (SPG) to monitor the air pressure in the tank.

The 1st stage regulator works by using a series of valves and chambers. It does this to reduce the high-pressure air in the scuba tank to an intermediate pressure. The air enters the regulator through the high-pressure port and moves to the first stage chamber.

From there, the air moves to the intermediate pressure chamber. This is where it is further reduces to a pressure of around 140 psi. This pressure then moves to the second stage regulator through a low-pressure hose.

1st stage regulators are crucial for diving because it delivers air to the diver at a safe pressure for breathing. Without a 1st stage regulator, the high-pressure air in the scuba tank would be too much for the diver’s lungs to handle. Without it, it could result in serious injury or even death.

Additionally, the 1st stage regulator allows for the attachment of a submersible pressure gauge. These are an essential piece of equipment for monitoring the air supply in the tank.

There are two main types of 1st stage regulators: piston and diaphragm.

Piston 1st Stage

A piston 1st stage regulator uses a piston to control the air flow.

Diaphragm 1st Stage Regulator

A diaphragm 1st stage regulator uses a flexible diaphragm.

Both types have their advantages and disadvantages, and the choice between the two often comes down to personal preference.

Like all scuba diving equipment, a 1st stage regulator requires regular maintenance and care to ensure it functions properly. Tecline recommend having your regulator serviced by a certified technician at least once a year.

Additionally, it is important to rinse your regulator with fresh water after each dive. Ensuring to store it in a cool, dry place to prevent corrosion.
