Submersible Pressure Gauge and Gauge ConsoleThe submersible pressure gauge (also called a pressure gauge or SPG) allows a diver to monitor the amount of air in his scuba tank so that he doesn't run out of air underwater. 0000039623 00000 n @@@!EYZ/W]5KNaRp3i6X@J8J>~vI9BuZj>m.c MF}~M-k>+j|V[JvWSZ};IbHD,>f}#! 0000794413 00000 n When the first stage body is tightened onto a tank, it creates a water-tight seal to the tank valve. The units of pressure may be given in bar (metric), or in psi (pounds per a square inch, imperial). This low-pressure hose carries intermediate-pressure air from the regulator first stage to the Buoyancy Compensator's (BC) inflator. It takes the intermediate pressure air from the regulator hose and reduces it to ambient pressure--a pressure equivalent to the air or water pressure surrounding a diver, allowing a diver to breathe from the second stage safely. 0000021740 00000 n 0000047437 00000 n How are the instruments al-Zahrawi describes in his encyclopedia compared with those used today? 0000000016 00000 n 0000057647 00000 n 2. 0000051146 00000 n 0000358358 00000 n 0000795447 00000 n Divers need to be sure that their inflator hose attachment will fit on to the BC inflator they plan to use.

It is absolutely essential in diving, for it allows divers to avoid running out of air underwater. 0000005596 00000 n 0000061161 00000 n %PDF-1.4 % The pressure gauge is connected to the regulator first stage by a high-pressure hose (HP hose) that feeds high-pressure air from the tank directly to the pressure gauge. 0000020673 00000 n Low-Pressure HoseLow-pressure hoses (LP hoses) transport air from a regulator first stage to its second stages. The alternate second stage is a back-up, that ordinarily is not used. When performing a brake service, why might it be a good idea to disassemble one wheel at a time? 4. The regulator second stage is attached to the first stage by a low-pressure hose. 0000001451 00000 n 0000002769 00000 n This sleeve must be held back to connect the hose to the BC inflator mechanism. In general, the alternate second stage should be attached to the Buoyancy Compensator (BC) or diver somewhere between the bottom of the diver's chin and the lower corners of his rib cage. Many second stage adjustments have a setting labeled "pre-dive" to help prevent free flow at the surface, and one labeled "dive" for easy breathing once underwater. A second -- in this case, red -- needle indicates the maximum depth a diver reaches on a given dive. The regulator second stage is the part of the scuba diving regulator that a diver actually breathes from. Alternate second stages are usually bright colors, such as neon yellow, which allows them to be quickly located. 0000036428 00000 n Alternate second stage mouthpieces should be a standard size to fit any diver's mouth--not a custom mouthpiece. 2. 0000006145 00000 n 0000025343 00000 n 0000058308 00000 n 3. The low-pressure inflator hose connects a regulator first stage to a buoyancy compensator's (BC) inflation mechanism, allowing divers to add air to the BC at the touch of a button. A black needle indicates a diver's current depth. An alternate second stage's LP hose is usually longer than the LP hose attached to the primary second stage. This feature helps to prevent regulator free flow (a state when air flows rapidly out of the regulator second stage without the diver breathing from it), which typically occurs when the breathing resistance has been lowered too much.

Five basic parts are usually included in a standard open water scuba diving regulator. The yoke is the metal oval that fits over the tank valve to hold the regulator in place. This seals closed the opening on the first stage. 0000003161 00000 n However, when the first stage body is disconnected from the tank, it is possible for water to enter the opening in the first stage, through which air passes from the tank to the regulator. 0000795359 00000 n The purpose of the purge button is to flood the second stage with air, forcing water out of the second stage. 0000019555 00000 n 0000006019 00000 n 0000022740 00000 n The compressed air inside a scuba tank is at an extremely high pressure, which could injure a diver who tries to breathe directly from the tank, and the regulator is necessary to reduce the pressure of the compressed air to a pressure the diver can breathe. YokeThe regulator first stage body is held against the scuba tank's valve through one of two methods: a yoke or a DIN fitting. This allows divers to add air to the BC from the tank at the touch of the button. 0000046257 00000 n 0000037829 00000 n 0000040227 00000 n 0000794160 00000 n 0000038351 00000 n 0000036166 00000 n There seems to be a problem serving the request at this time, {"modules":["unloadOptimization","bandwidthDetection"],"unloadOptimization":{"browsers":{"Firefox":true,"Chrome":true}},"bandwidthDetection":{"url":"https://ir.ebaystatic.com/cr/v/c1/thirtysevens.jpg","maxViews":4,"imgSize":37,"expiry":300000,"timeout":250}}. 0000358128 00000 n 0000004459 00000 n Vd60(x*p 2r@Pp v b endstream endobj 182 0 obj <>>> endobj 183 0 obj <> endobj 184 0 obj >/PageWidthList<0 425.197>>>>>>/Resources<>/Font<>/ProcSet[/PDF/Text]/Properties<>>>/Rotate 0/TrimBox[0.0 0.0 425.197 595.276]/Type/Page>> endobj 185 0 obj <> endobj 186 0 obj <> endobj 187 0 obj <>stream Schematics- Apollo USA Scooters (DPV, Underwater Vehicles), AV-2 Evolution 202439 - Present updated 2017.0330, AV-2 Evolution 201788 - 202438 updated 2019.0529, AV-2 Evolution 201582 - 201787 updated 2017.0421, AV-2 Evolution 201197 - 201581 updated 2017.0330, AV-2 Evolution 200569 - 201196 updated 2017.0330, Important Guidelines For Safe Use of AV1 2016.09, Important Key Original Parts No Longer Available 2016.08, Bio Filter, Model Year 2004 - Present Moisture & Clean Air Updated 6, Bio Filter, Model Year 2000 - 2004 Moisture & Clean Air, Owners ManualsSchematics - Dry Suit Valves, Schematics - Regulators 1st Stages Identify model number by features and 2nd stage, A320 Nitrox DIN 5/8, Chromed Brass Sold with 2nd Stages BAS - Bio, A320 Nitrox DIN M26, Chromed Brass Sold with 2nd Stages BAS - Bio, A320 Nitrox Yoke, Chromed Brass Sold with 2nd Stages BAS - Bio, A120, Aluminum, Fixed Yoke, 2 HP Ports Sold with 2nd Stage Bio - Prestige ex2000, A110 Moisture System, Aluminum, Fixed Yoke Sold with 2nd Stage Bio - Prestige ex2000, A107 Moisture System, Chromed Brass 2nd Stages Prestige ex2000 - Prestige Balanced, A105 Moisture System, Chromed Brass Sold with 2nd Stage Prestige not balanced (NB), A102, Chromed Brass, 2 HP Ports 2nd Bio - Ecodiver - Prestige ex2000 - Prestige Balanced - Prestige, A102, Chromed Brass, 2 HP Ports, through Model Year 1993 Sold with 2nd Stage Prestige (NB), A101, Chromed Brass, 1 HP Port 2nd Ecodiver - Prestige ex2000 - Prestige Balanced - Prestige(NB), Schematics - Regulators 2nd Stages Identify model by full name on top cover, Bio Model Year 2007 Not marked with year, check schematic to compare with earlier model, Bio Cover appears same as later model above, check schematic to compare versions, Ecodiver, Prestige ex2000, Prestige Balanced, Prestige not balanced, Schematics - BCD Inflators, Safety / Quick Relief Valves, Power Inflator, Ecodiver - EX2000Corrugated Hose, Prestige, Safety/Quick Valves, Bio Control - Prestige, Specialty: All Vehicles & Regulator Service, Specialty: Dry Suits, Regulators and All General Service, 10545 Aurora Avenue North, Seattle, WA 98133, Phone 800.231.0909 425.290.9890 Fax 877.756.7240 E-mail apollous@mac.com | 2022 Apollo Sports USA Inc.
