Compact dust extractor
The machine is equipped with a compact dust extractor (filtering
installation) with or without a CO
2
fire extinguishing device, an
oversized material collector and a spark arrester. The suction
power is 2000 m
3
/h.
The suctioned air is channelled into the compact dust extractor via
a system of pipes. There filter elements (sintered lamellar filters)
take over clarifying the exhaust gases which have been produced
in laser cutting and laser welding. The cycles for purging the filter
inserts are controlled according to the jet-pulse principle
(dependent on differential pressure).
An acoustic alarm goes off and the warning lamp lights up if a fire
is detected in the crude gas space or the clean gas space. The
slide valves in the supply air and exhaust air lines are closed
immediately. The entire interior of the compact dust extractor is
flooded with CO
2
(in the form of gas).
An alarm is triggered if there is a fire in the dust container. The
extinguishing device is not activated.
The CO
2
extinguisher can be manually triggered with the manual
fire alarm.
