Cylinder:
Aluminium lined Carbon Fibre wrap coated in glass fibre wrap finished with an Epoxy Resin top coat (Dräger Tweed).
Carry using main body of valve, facing away from body.
Store valve pointing down.
From closed to fully open, no less than 2 full turns (3.5 Revolutions). Don’t Over Tighten
Marked with cylinder re-test date.
300 bar 2454 litres air – 9ltr water capacity.(1.1 correction factor )
Pressure tested every 5 yrs with 20 year lifespan.
Never completely drain cylinder, leave min of 2 bar in to prevent internal contamination & moisture ingress.
Black & white quartering on shoulders denotes breathable air.
9 x 300/1.1 = 2454 Litres

8. Reducer Anti-tamper disk Longer Thread for 300 bar
Built in Anti-vibration O-ring
Spring loaded reducer mounting
Pneumatic Whistle
2nd wearer ‘Y-Piece’
Pneumatics.
First stage pressure reducer – Nickel Plated Brass, with inbuilt mechanical whistle.
Reduces from 300 bar to 6 -9 bar.
10 year service life.
Threaded hand wheel to connect to cylinder, finger and thumb only!
Compression ‘O’ ring acts as anti-vibration device. (Inbuilt into hand wheel)
Sintered bronze filter.
2 outlet ports, one high pressure, one medium pressure. (Medium pressure port incorporates pressure relief valve – hose lifts very slightly off its seating) bars.
Pneumatic whistle operates between 60 +/- 5 bars
Electronic whistle in the bodyguard operates at 74 Bar (There will be some time delay between operation of both LPWW’s this is normal and due to the electronic monitoring unit detecting cylinder contents).
O-Ring & Bronze Sintered Filter changed every 12 Months
Choke screw set to 25L/Min
Hoses.
Flexible anti-kinking hose made from Ethylene-Propylene-Diene-Monomer (EPDM) rubber.
Medium pressure travels from medium pressure port through a small ‘Y’ piece to the Demand Valve via female quick release coupling. From the other side of the ‘Y’ piece, there is a dual purpose hose for used for second wearer attachment
High pressure travels from high pressure port to Electronic Monitoring Unit (EMU). From here there is a series of wires which are routed through a protective hose to the Body guard 7000.
High pressure hose is different from medium pressure - inside it is a fine bore copper capillary tube coil wound round a multi-stranded phosphor bronze wire. Capillary tube and wire are brazed to each of the end fittings of the tube/wire assembly.
High pressure air flows through the capillary tube.
O-ring for pressure seal
Bronze sintered filter

Spark-proof buckles
Harness & Cylinder Strap.
Two Neoprene Polyester photo luminescent hose retaining flaps with lift to spot locking studs.
Quick release waist belt & shoulder straps constructed from flame retardant woven polyester wrap coated with flame retardant Neoprene. Trident clip buckle made from flame retardant Nylon.
Universal cylinder strap made from 100% Navy Nomex.
Camlock Buckle made from glass filled Nylon.
All straps manufactured containing 50% Kevlar webbing meeting EN 137.
Stainless steel spark-proof shoulder strap buckles.
Designed to carry 2/3 weight on hips.
Curved trident clip on waist belt assembly
The shoulder and waist padding are manufactured using a compression forming process.
The inner padding is produced from a flame retardant, closed cell, fully vulcanised foam. The
inner liner is then covered with outer layers of woven polyester covered with Neoprene. The
outer edges are covered with a stitched binding of the same material as the outer layer.

Reducer output 6-9 bar (dynamic & static pressures )
Reducer relief valve lift off pressure bar.
Choke screw set to 25 lts per minute.
Pneumatic LPWW operates at 60 Bar + or – 5 Bar

16. Pressures 300 Bar – Nominal Charge (100%)
270 Bar – Minimum for full test (New Cylinder) (90%)
245 Bar - Minimum on completion of General test
240 Bar – Minimum Initial Entry (80%)
150 Bar – Minimum Re-entry (50%)
120 Bar – Minimum for Decontamination (40%)
74 Bar – Bodyguard LPWW (25%)
60 +/- 5 Bar – Pneumatic (failsafe LPWW) (20%)
Any rounding up or down of figures are within the tolerances
Bar Pressure x Water Vol. / 1.1 = Remaining volume of air (– 600l for safety margin)
Consumption rate 50l/min
Remaining vol. / consumption rate = Time remaining to whistle
150 bar calculated to give 12 minutes before TOW.
120 bar calculated to give just under 8 minutes before TOW.
74 bar is calculated to give a 12 minute safety margin.
60 Bar gives a 9.8 minute safety margin and is set by Draeger as a failsafe should the Bodyguard fail we still have a LPWW
