Description

2.1 Product overview
The Dräger saver CF (constant-flow) is an emergency escape breathing apparatus that provides respiratory protection to escape from a contaminated or oxygen- deficient environment to a safe breathing environment.
The main features of the product are:

• The respiratory protection equipment is contained in a carrying bag that has a soft or hard case. If the bag is black it indicates that the bag material has anti-static properties. The bag has a neck strap to carry the product.
• The air cylinder is fitted inside the carrying bag but has a pressure gauge (Fig 1, Item 6) that is visible outside the bag. When the cylinder is full it provides a nominal duration of 10 or 15 minutes (see Section 2.1.1).
• The cylinder valve/reducer (Fig 1, Item 4) has an automatic activation device that is operated by removing a two-pronged locking clip (Fig 1, Item 3). The locking clip is connected by a strap to a sprung gate clip (Fig 1, Item 2) that is in turn connected to a D-ring (Fig 1, Item 1) on the inside of the lid. This arrangement automatically removes the locking clip as the carrying bag is opened. When the valve/reducer is activated, it reduces the cylinder pressure to a medium pressure, and a preset nozzle inside the valve/reducer provides a constant flow of breathing air to the escape hood.
• A whistle (Fig 1, Item 5) on the valve/reducer emits a warning when the cylinder pressure falls to 10 bar to indicate the end of the rated duration.
• The escape hood (Fig 2) has a rubber ring that seals around the neck, and an internal nose cup that fits over the nose and mouth to supply air to the wearer.
• There is an anti-tamper tag (or tags) (Fig 3) fitted on the lid of the carrying bag to allow an inspector to quickly identify that the bag has not been opened. The soft-case bag has a single anti-tamper tag (Fig 3, A), and the hard-case bag has two anti-tamper tags (Fig 3, B).

2.1.1 Air cylinders
The saver CF10 version has a 2 litre aluminium cylinder – nominal duration of 10 minutes.
The saver CF15 version has a 3 litre steel cylinder – nominal duration of 15 minutes.
The saver CF15 CC version has a 3 litre carbon-composite cylinder – nominal duration of 15 minutes.
2.2 Intended use
When this product is used with an approved air cylinder it provides the wearer with respiratory protection for escaping from contaminated or oxygen- deficient conditions. The air cylinder used with this product must be a certified Dräger cylinder; otherwise the operation of the product may be impaired. Contact Dräger for further information.
The product version marked with the symbol is recommended where the product is stored in, or regularly exposed to, atmospheres where airborne hydrocarbons or chemical, fuel or oil vapours may be present.
Operating temperature range: -15 °C to 60 °C.
2.3 Limitations on use
The saver CF15 version (with 3 litre steel cylinder) exceeds 5 kg. This is considered to be unsuitable (as defined in EN 1146) to be carried by the wearer for more than 8 hours.
Use in potentially explosive atmospheres
Do not charge the cylinder in a potentially explosive atmosphere.
saver CF Series combinations that are supplied in a black soft-case bag or hard-case bag have anti-static properties and are type tested as suitable for use in potentially explosive atmospheres. The combinations are suitable for use in hazardous areas up to and including zone 0 and zone 20. The combinations can be used in atmospheres containing gases of the gas explosion group IIC.
saver CF Series combinations that are supplied in an orange soft-case bag are not suitable for use in potentially explosive atmospheres.

4.2.2 Air cylinder charging
NOTICE
The charging procedure in this section describes recharging a cylinder that has been fully discharged during use of the saver CF. If during a check the cylinder pressure gauge is found to be in the red area, do not use this procedure and inform trained service personnel or Dräger immediately.
WARNING
Air quality for compressed-air cylinders shall meet the requirements for breathing air according to EN12021.

•  The charging connector is a G5/8 connector as per EN 144-2.

• Refer also to the instructions supplied with the cylinder and the charging unit for recharging the cylinder.

• Only charge compressed-air cylinders which:
  ○ Conform to national standards.
  ○ Feature the original manufacturer’s test date and test mark.
  ○ Have not exceeded the test date indicated on the cylinder by the last testing station.
  ○ Are not damaged.

• Dräger recommend a charge rate of 27 bar/minute (rapid charging will increase the temperature resulting in an incomplete charge).

• To prevent overcharging of the cylinder, Dräger recommend using a pressure-limiting device on the charging compressor.
  1. If the carrying bag is closed, open the lid and remove the hood from the bag.
  2. Remove the air cylinder as follows:
  ○ Soft-case carrying bag: release the hook-and-loop strap and carefully remove the cylinder.
  ○ Hard-case carrying bag: remove the screws from the carrying bag body (Fig 5) (5 mm hexagon key and a 10 mm socket required), fully open the carrying bag body and then carefully remove the cylinder. Remove the lid from the slot on the bag.
  3. Using the probe (Fig 6, Item 1) (Dräger part no. 3310488), press the plunger down and insert the locking clip (Fig 6, Item 2).
  4. Remove the protection cap from the charging port and connect the charging adaptor (Fig 7).
  5. Recharge to the rated working pressure of the cylinder (200 bar).
  NOTICE
  Compression of cylinder air can cause a small temperature increase during refilling, resulting in an incomplete charge. If necessary, top-up the cylinder when it cools.
  As charging commences, the whistle will sound briefly until the cylinder pressure reaches approximately 10 bar.
  6. When the cylinder is fully charged, vent pressure from the charging hose and then remove the charging adaptor from the valve.
  7. Refit the air cylinder as follows:
  ○ Soft-case carrying bag:
  i. Fully insert the cylinder into the carrying bag.
  ii. Fit the pressure gauge shroud into the cut-out section in the side of the bag.
  iii. Connect the hook-and-loop strap around the cylinder.
  ○ Hard-case carrying bag:
  i. Place the cylinder on the fully open case (Fig 8) and fit the neck strap as shown.
  ii. Close the carrying bag body, ensuring that the pressure gauge shroud remains in its holder.
  iii. Fit the securing screws (5 mm hexagon key and a 10 mm socket required). Dräger recommend a torque of 2 Nm (1.5 lbf ft). The nylon in the locknut must exhibit an
  interference with screw threads – if interference is not felt, replace with a new M6 self-locking nut.
  iv. Refit the lid into the slot on the bag.
  NOTICE
  Route the rubber hose in such a way that the bend radius is not too acute and the hose is not stretched, compressed or twisted.
  8. Carefully roll up the escape hood, ensuring that the visor is not creased or folded, and fit the hood into the carrying bag (Fig 9).
  9. Seal the lid along the hook-and-loop fastening strip leaving sufficient opening to insert a hand and, taking care not to detach the locking clip from the cylinder valve, connect the sprung-gate clip (Fig 1, Item 2) to the D-ring (Fig 1, Item 1).
  10. Fit the anti-tamper tag(s) and close the lid (Fig 3).
