Important Safety Information
Operator's Responsibility for Patient Safety
For correct and effective use of the product and in
order to avoid hazards it is mandatory to carefully
read and to observe all portions of this manual.
The design of this device, accompanying literature, and
the labeling on the equipment, take into consideration
that the purchase and use of the equipment are
restricted to trained professionals, and that certain
inherent characteristics of the equipment are known to
the trained operator. Instructions, warnings, and
caution statements are limited, therefore, largely to the
specifics of the Dräger design. This publication
excludes references to various hazards which are
obvious to a medical professional and operator of
respiratory care equipment, to the consequences of
misuse of such equipment, and to potentially adverse
effects in patients with abnormal conditions. Product
modification or misuse can be dangerous.
Dräger Medical, Inc. disclaims all liability for the consequences of product alterations or modifications, as well
as for the consequences which might result from uses
of the product not covered by its intended use or from
the combination of this product with other products
whether supplied by Dräger or by other manufacturers
if such a combination is not endorsed by
Dräger Medical, Inc.
Limitation of Liability
Dräger Medical, Inc.'s liability, whether arising out of or
related to manufacture and sale of the goods, their installation, demonstration, sales representation, use,
performance, or otherwise, including any liability based
upon Dräger Medical, Inc.'s Product Warranty, is subject to and limited to the exclusive terms and conditions
as set forth, whether based upon breach of warranty or
any other cause of action whatsoever, regardless of
any fault attributable to Dräger Medical, Inc. and
regardless of the form of action (including, without limitation, breach of warranty, negligence, strict liability, or
otherwise).
THE STATED EXPRESSED WARRANTlES ARE IN
LlEU OF ALL OTHER WARRANTIES, EXPRESSED

Dräger Medical, Inc. shall not be liable for, nor shall
buyer be entitled to recover any special incidental, or
consequential damages or for any liability incurred by
buyer to any third party in any way arising out of or
relating to the goods.
The operators of ventilator systems must recognize
their responsibility for choosing appropriate and reliable
electrical and gas supplies for the support of all systems. Backups for the supplies and alarm functions in
case of a supply failure are mandatory while using lifesupporting ventilators. Patient safety may be achieved
through a wide variety of different means ranging from
electronic surveillance of equipment performance and
patient condition to simple, direct observation of clinical
signs. The responsibility for the selection of the best
level of patient monitoring lies solely with the equipment
operator.

Service = measures to maintain specified
condition
Repair = measures to restore specified
condition
Maintenance = inspection, service, and repair,
where necessary
General WARNINGS and CAUTIONS
WARNING !
Strictly follow Operator's Instruction Manual!
Use of the compressor requires full under-
standing and strict observation of all portions
of these instructions. The equipment is only to
be used for the purpose specified under
"Intended Use" (page 9). Observe all
WARNINGS and CAUTIONS as rendered
throughout this manual and on labels on the
equipment.
WARNING !
DANGER, risk of explosion if used in the
presence of flammable anesthetics.
The equipment is neither approved nor certified for use in areas where combustible or
explosive gas mixtures are likely.
WARNING !
Do not spray flammable liquids near the
compressor. Fire hazard!

Controls are designated as »Control Name«, e.g. »NNNN«
WARNING !
Air supply to life-supporting ventilators:
If the compressor is used to supply air to life-
supporting ventilators, an adequate alternative
supply of medical air must be ensured in case
of a malfunction of the compressor!
Life-supporting ventilators supplied with air
from the compressor must be equipped with a
alarm function that is activated if the supply

Precautions During Preparation
Precautions During Care
Precautions During Preparation
WARNING !
Installation of the Medical Air Compressor
may be performed by factory trained service
personnel only. Follow installation procedures
on pages 20 to 23 of this manual.
WARNING !
To maintain grounding integrity, connect only
to a "hospital grade" power outlet. Always
disconnect supply before servicing.
CAUTION !
The medical air compressor must not be started
up before it has been properly installed on a
mobile cart.
The compressor unit may be damaged as a
result of poor air circulation if disregarded!
Precautions During Care
CAUTION !
The compressor housing consist of materials that
are sensitive to certain organic solvents sometimes used for cleaning and disinfecting
(e.g., phenols, halogen releasing compounds,
oxygen releasing compounds, strong organic
acids, etc.). Exposure to such substances may
cause damage that is not always immediately
apparent.
CAUTION !
Follow all accepted hospital procedures for
disinfecting parts contaminated by body fluids
(protective clothing, eyewear, etc.).
CAUTION !
Do not connect more than one ventilator to the
compressor!
Compressor overload may result.
CAUTION !
Do not operate compressor in salty air, as this
may cause the non-return valves in the

While switched on, the compressor continuously
monitors pressure in the central medical air system.
If the pressure drops below 40-5 psi (2,7-0,3 bar), the
compressor will automatically supply medical air to the
ventilator to which it is connected. The compressor
switches off its supply and remains on standby when the
pressure in the medical air pipeline system returns and

are sensitive to certain organic solvents sometimes used for cleaning and disinfecting
(e.g., phenols, halogen releasing compounds,
oxygen releasing compounds, strong organic
acids, etc.). Exposure to such substances may
cause damage that is not always immediately
apparent.
CAUTION !
Follow all accepted hospital procedures for disinfecting parts contaminated by body fluids (protective clothing, eyewear, etc.).
To prevent any damage, we recommend that only detergents and disinfectants are used that are compatible with
the materials used in the compressor and its accessories,
e.g. surface disinfectants on the basis of aldehydes,
alcohol, or quarternary ammonia compounds for
disinfection of the main unit.
Ensure that all disinfectants are registered with the U.S.
Environmental Protection Agency for use as intended.
● Wipe compressor housing, hoses and cable with
disinfectant. Always follow the instruction labels
specifically with respect to prescribed concentrations
and the necessary exposure times.

Ambient air drawn via intake filter 1 is compressed in the
compressor unit 2 and cooled in the cooling coil 3.
Solenoid valve 4 briefly opens the system when the
compressor starts up.
The compressed air is cleaned by prefilter 5. Condensate
is collected and removed via water trap 6.
Heat exchanger 7 re-heats the purified air in order to
prevent further condensation before the air reaches membrane drier 9, where it is dehumidified to a dew point at
least 9 °F (5 °C) below ambient temperature.
The dehumidified air flows via resistor orifice 10 and
non-return valve 11 to the pressure vessel 12, where it is
dispensed at relief valve protected connector 14.
In standby mode, the ventilator draws air from the
medical air pipeline system via port 15, non-return valve
17 and self-closing coupling 13. The compressor unit 2 is
in standby.
Whenever the pressure in the medical air supply drops
below 40-5 psi (2,7-0,3 bar), pressure switch 16 will activate compressor unit 2.
When pressure in the supply pipeline returns to 50 psi
(3,4 bar), pressure switch 16 will switch compressor
unit 2 off again.
Operating Instructions Medical Air Compressor
Pressure regulator 8 limits system pressure to 59 psi
(4 bar) and relief valve 14 protects the unit against
excessively high pressure from the medical air pipeline
system.
