2 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

4.2 Maintenance tasks
4.2.1 Visual inspection
Carry out a visual inspection, checking the full breathing apparatus including
all component parts and accessories. Check that the equipment is clean and
undamaged, paying particular attention to pneumatic components, hoses and
connectors. Typical signs of damage that may affect the operation of the
breathing apparatus include impact, abrasion, cutting, corrosion and
discoloration. Report dirty or damaged equipment to trained service personnel
or Dräger, and do not use until faults are rectified and the product is cleaned.
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).
