Regulator set Each primary sidemount cylinder requires a regulator 1st stage, a regulator second stage and a submersible pressure gauge (SPG). The left hand cylinder will also include a low-pressure inflator (LPI) for BCD inflation. If a drysuit is used, the drysuit inflator will be attached to the right hand cylinder.
Draeger twin hose two stage demand regulator. The most striking and well recognized example of vintage scuba gear is the twin-hose or double hose regulator, a popular style of regulator in the early years of scuba diving, since Jacques-Yves Cousteau and Emile Gagnan pioneered the first such design, the C45 Scaphandre Autonome, which was marketed in the USA (along with a tank and harness) as ...
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
A pony bottle or pony cylinder is a small diving cylinder which is fitted with an independent regulator, and is usually carried by a scuba diver as an auxiliary scuba set.In an emergency, such as depletion of the diver's main air supply, it can be used as an alternative air source or bailout bottle to allow a normal ascent in place of a controlled emergency swimming ascent.
In 7.2 to 10 °C (45.0 to 50.0 °F) water, most regulators will ice up if the diver aggressively purges the demand regulator for just 5 to 10 seconds to fill a small lift bag. For this reason an important rule in cold water diving is never to intentionally free flow the regulator.
The news sent Wells Fargo's stock up sharply Thursday as investors speculated that the bank, which has been kept under a tight leash by regulators for years, may be able to rebuild its reputation ...
In open circuit free-flow systems, the air is supplied at an approximately constant rate, and the diver uses only a relatively small part of the passing gas. The original Aqua-Lung regulator was a single stage unit, packaged in a circular brass housing mounted on the cylinder valve behind the diver's neck.
