HiLAN pneumatic motor GA519/GA520R/GA529
3.2

Intended use

The HiLAN pneumatic motors GA519, GA520R, and GA529 are used for
powering the Aesculap Hi-Line handpieces in microsurgery, neurosurgery,
spinal surgery, ENT, and maxillary surgery, as well as in orthopedics.

Operating principle

3.3.1

HiLAN pneumatic motor

In the HiLAN pneumatic motor, the energy provided by the compressed-
air supply is converted into rotary movement.
The HiLAN pneumatic motor is equipped with a safety stop, which pre-
vents any unintended startup of the HiLAN pneumatic motor.
3.3.2

Compressed-air tubes

All compressed-air tubes have a fast-lock coupling. Consequently, the
compressed-air tube need not be disconnected from the compressed-air
supply when changing the HiLAN pneumatic motor.
3.3.3

Exit-air recycling via the compressed-air tube

■
Complete exit-air recycling (Aesculap Dräger system): The exit air is
passed outside the operating room. Absence of air turbulence in the
operating room: no effect on either ambient air temperature or
hygiene in the operating room.
■
Partial exit-air recycling (DIN connection and others): The exit air
emerges from the tube end, either directly or through a diffuser inside
the operating room.
3.3.4

Foot control

The foot control GA521 is equipped with a forced ventilation system. As
soon as the foot control pedal is released, the supply air is vented on the
motor side. This allows the HiLAN pneumatic motor to stop more rapidly.

Danger of fire and explosion when operating
devices that run on oxygen!
►
Never operate the HiLAN pneumatic motor with
DANGER
oxygen.
►
Operate the HiLAN pneumatic motor with com-
pressed air or nitrogen.
Operating pressures in excess of 10 bar will dam-
age the HiLAN pneumatic motor!
►
Set an operating pressure of between 6 bar and
CAUTION
10 bar.
4.1.1 Operation with central gas supply according to DIN 13260
and EN 737
The gas supply must provide clean, dry air and must be set as follows:
Nominal operating pressure
Maximum allowable operating pressure
Minimum operating pressure
Minimum gas-supply delivery
4.1.2 Operation with compressed-gas cylinders according to
DIN 4664
The following conditions must be met:
■
Compressed air or nitrogen is used
■
An adequate stock of full gas cylinders is in place
■
Cylinder pressure reduced to operating pressure of 6 bar to 10 bar
through a pressure reducer (e.g., GA099)
►
Operating pressure must be read from the scale on the device and set
with the T-screw.
