Especially in laser processes with smoke and nano dusts as emissions,
deposits in hoses, pipes and on extraction elements cannot be
completely avoided. These deposits can become loose and leak out, e.g.
when the hose is changed.
Check hoses, pipes and sensing or extraction elements regularly for
damage, contamination and wear. Replace or clean these as required.
For transport reasons, extraction elements or extraction arms are usually delivered
disassembled along with the system. Please firstly check if all parts have been delivered and
not been damaged during transport.
To avoid overheating of the filter and extraction system, fresh air may
also have to be supplied for cooling (temperature at the intake max.
40°C).
Enclosed Laser Compartment

Provide for sufficient air supply to avoid negative pressure within the compartment
(slots, holes opposite to the extraction connection).

Guide airflow as laminar as possible over a smooth surface (e.g. work table).

Dimension the airflow rate of the filter and extraction system such that no smoke can
escape from the compartment, but at least 0.4 m/s within the laser compartment.
Partially Sealed-off Laser Compartment

Partially open systems require a higher airflow dimensioning than for enclosed
systems. It is necessary to install the extraction as close as possible to the emission
source (e.g. suction nozzle, flat shield or similar) to avoid losses. If required, the
extraction nozzle must be moved along with the laser flame.

Dimension the airflow rate of the filter and extraction system such that no smoke can
escape from the laser compartment.
Extraction Arm Mounted on Extraction and Filter System
•
If not already pre-installed at the factory, the mounting flange and the bracket must
first be mounted on the system. For this, remove the system lid from the extraction
system (to avoid damaging the filters during installation). When mounting on to an
FP150 system, please observe that chips may fall into the electronics. Please
contact your country representative. if in doubt.
•
The extraction arm can now be attached to the mounting flange.
•
Please observe sufficient stability of the system, incl. the mounted extraction arm
(due to the lever) - additional securing devices may be necessary (ground anchors,
etc.).
•
Please observe that if the extraction capacity of the extraction arm is too high, there
may be whistling noises at the extraction tip. In this case, please reduce the
system's extraction capacity by turning it back somewhat.
