What is a 2nd Stage Regulator?
2nd stage regulators are developed to decrease the high pressure in two phases. They need minor adjustments and supply a more consistent delivery pressure despite transformations in inlet pressure. Second Stage Regulators are not utilized for reducing tank pressure and, thus, must be established downstream of a first stage regulator for secure and accurate operation.Second stage regulators operate at a pressure provided by the first stage regulator and also lower that to a pressure that can be operated by devices.
You can buy these 2nd stage regulators from these brands: SEAC, Mares, Apeks, Metalsub and Aqualung.
A 2nd stage regulator is a crucial component of a scuba diving regulator system. It is the part of the regulator that the diver breathes from, delivering air on demand.
A 2nd stage regulator is designed to be used in conjunction with a 1st stage regulator. The 1st stage reduces high pressure air from the scuba tank to an intermediate pressure, which is then delivered to the 2nd stage regulator through a low pressure hose. The 2nd stage is responsible for delivering the air to the diver´s mouth when they inhale and expelling exhaled air when they exhale.
Key features of a 2nd stage regulator include:
Demand Valve: The 2nd stage regulator features a demand valve mechanism that opens when the diver inhales. This allows the flow of air from the 1st stage regulator into the diver´s mouth. The demand valve ensures that air is supplied only when the diver needs it, conserving air and reducing the effort required for breathing.
Exhaust Valve: The 2nd stage regulator also includes an exhaust valve that allows the diver to exhale air and release it from the regulator. The exhaust valve typically releases the exhaled air through ports located on the sides or bottom of the regulator.
Breathing Resistance Adjustment: Many 2nd stage regulators offer a breathing resistance adjustment feature. This allows divers to customize the ease of inhalation based on their personal preference and diving conditions. The adjustment may be in the form of a knob or lever that allows the diver to increase or decrease the airflow resistance.
Purge Button: The 2nd stage regulator is equipped with a purge button or purge valve that allows the diver to clear water from the regulator if it enters during the dive. By pressing the purge button, a burst of air is released, forcing water out of the regulator.
Mouthpiece: The 2nd stage regulator has a mouthpiece that the diver bites on to create a seal and facilitate effective air delivery. The mouthpiece is typically made of comfortable and durable materials such as silicone.
In summary, a 2nd stage regulator is the part of a scuba diving regulator system that delivers air to the diver when they inhale. It incorporates a demand valve, exhaust valve, breathing resistance adjustment, purge button, and mouthpiece to ensure optimal breathing performance and comfort underwater.
