Stealth SC Semi closed circuit Mixed Gas DEFENCE COMMERCIAL Underwater Apparatus

Stealth SC (Semi Closed) is a product of operations where simplicity, ease of use the highly successful and operationally and ruggedness are a necessity. Should an proven range of Stealth Underwater extended endurance be required, the twin HEAD OFFICE Breathing Apparatus (UBA). cylinder assembly may be charged to 300 Enterprise Drive bar. This extended endurance is matched Westhill Stealth SC - Principle of Operation by the carbon Dioxide (cO ) scrubber Aberdeen 2 AB32 6TQ Stealth Sc is a back worn semi closed canister, which is based on the field proven T: +44 (0)1224 740145 circuit UBA that is designed for a range Stealth UBA. F: +44 (0)1224 740172 of operations including: • 60m using or gases 1. Mine countermeasures (McM) Explosive • 54m using standard NATO gases Ordnance Disposal (EOD) to a maximum • Brief excursions to a maximum depth of 6

depth of 60m using trimix or heliox gases. msw on 100% O 2 with short duration excursions to 15 msw (dependant upon 2.McM EOD operations to a maximum local exposure regulations) depth of 54m using nitrox gases. GLOBAL LOCATIONS 3. Special Operations to a maximum depth Aberdeen of 6 msw on 100% O 2 with short duration Chertsey excursions to 15 msw (dependant upon Portsmouth local oxygen exposure regulations). Bremen Dubai Cape Town Gas is stored in a back mounted twin 2 litre Perth cylinder assembly, which is monitored by a Sydney gauge and is supplied to the breathing circuit via an adjustable constant Mass Flow (cMF) metering valve. Additionally gas is also supplied to a demand valve that automatically provides counterlung volume during descent, whilst serving as a manual gas addition (bypass) valve.

Aberdeen • Dual Mode Bite Mouthpiece Chertsey Portsmouth Construction Bremen The XBS is housed in a lightweight Dubai eXternal Breathing System moulded plastic case containing two light - Cape Town The eXternal Breathing System (XBS) has weight 9 litre 300 bar composite low Perth been designed for use with Stealth Sc to Sydney magnetic cylinders. Each cylinder has an independent shut off valve, contents gauge, first stage reducer and safety relief valve. Both first stage reducers supply medium- pressure gas to a switch over block enabling the diver to switch between cylinders.

Application The XBS is available in two variants; a two cylinder nitrox system for open discover more circuit emergency bailout and a two cylinder www.divexglobal.com oxygen system for extended decompression.

Due to its low magnetic design, the XBS may be placed in the vicinity of the diver during McM EOD operations. eXternal Breathing System DB109-MDS-483 R2
