Safety instructions for fire
hazards
DANGER
The Extraction Unit LAS 260.1 is designed solely for the
extraction of airborne dusts and gases produced during laser
machining in non-flammable concentrations. The filtration
system is designed for the separation of dusts and gases that
are not potentially explosive. It is prohibited to use the
equipment for the extraction of potentially explosive mixtures.
Before using the unit you must inform yourself about the
flammability and/or explosiveness of the vapors, gases, and
dusts that arise during processing. It is prohibited to use the
equipment for the extraction of potentially explosive and
flammable mixtures.
So that you can properly assess the explosion and fire hazard
and define appropriate safety measures, pleaseinform yourself
about the key parameters of your dust that are relevant in terms
of technical safety.
To avoid the risk of fire and explosion, the system must never
be used to extract e.g. hot, glowing, smoldering parts, glowing
ashes/shavings/filings, or smoldering cigarettes.
If the Extraction and Filtration System is used improperly, the
risk of a fire hazard cannot be ruled out, so it is recommended
that a fire extinguisher is provided in the immediate vicinity or
that an extinguishing system is installed.
Fire extinguishers with suitable extinguishing agents should be
chosen based on the reactive properties of the substances
sucked into the overall system.
In the event of fire:
1. Immediately switch off the unit.
2. If possible, close the inlet opening to prevent the supply of
oxygen.
3. If possible, close the outlet openings.
4. Bring the fire extinguisher into position and spray
extinguishing agent through the intake opening.
5. Do not open any other parts of the enclosure.
DANGER
Please note that the filter materials themselves are also
flammable, and that toxic gases and vapors can be released
when they burn.

Function and operation
Intake nozzle
Air distribution
Filter
Outlet grille
Vacuum generator
The blower installed in the LAS 260.1 generates a vacuum at
the intake connector or at the relevant connected collection
elements. As a result, impurities in the air can be collected and
sucked out directly at the point of creation.
The contaminated air is guided through the filters in the
LAS 260.1 and purified.
The purified air passes through an integrated muffler and
comes out through the outlet grille on the rear of the unit. If
recirculated air mode is not required, the outlet grille can simply
be rotated to quickly and easily reconfigure the setup so that
the outlet air is discharged rather than being fed back in. The
filtered air is then directed into an air outlet system.

Device variant and
application
Application LAS
The LAS 260.1 is used for extraction and filtration of dry and
non-combustible dusts in air mixtures that are not potentially
explosive and are produced during laser machining processes.
Areas of application:
- Laser cutting
- Laser engraving
- Laser structuring
- Laser sintering
The LAS 260.1 is to be used on laser workstations or laser
machining stations in such a way that the hazardous
substances that arise are extracted directly at the point where
they are generated.
Filter FK
Pre-filter: Particulate filter cassette F9
- Raw gas intake
-  Pleated filter F9
Filter class ISO ePM1 80% in acc. with ISO 16890
Main filter: Combined filter cassette H14A10
-  Pleated filter H14
Filter class HEPA H14 in acc. with EN 1822
-  Adsorption filter, activated carbon, 10 kg
Thanks to their depth effect, the pre-filters are particularly well
suited to the separation of laser smoke. A large part of the
particles in the laser smoke is adsorbed. Finest suspended
solids are retained by the HEPA H14 filter of the combined filter
cassette H14A10. This guarantees a particle separation rate of
99.995%. The activated carbon layer is used for filtration of
gases, vapors, and odors.
