1 Safety Warnings
This device is intended to be used as part of a safety system which may be used to protect personnel
and equipment from possible injury, damage, or loss.
As such it must be installed and wired according to these instructions and tested by suitably qualified
persons. No attempt may be made to tamper with the parts, open them, or use them outside of the
parameters contained herein.
The units are only designed to be fixed to surfaces using their inbuilt fixing holes. They must not
come into contact with each other or any other moving part when in use. The parts should never be
subject to impact or mechanical strain.
Safety switches should never be defeated or bypassed. It is imperative that all steps are taken to
ensure that any spare actuators are made unavailable, such that they cannot be used to defeat the
switch or reduce the protection offered by the system in any way.

2 Concept
I-Extract is Lasermet’s fume extraction system specifically designed for the extraction and filtration
of gases and emissions created by lasers during laser welding, laser cutting and laser cladding
processes.
Designed as an integrated part of Lasermet’s “Laser Castle” laser safety cabin, the I-Extract has
ample power to extract the appropriate volume of emitted gases produced in the cabin.
The specific CFM (cubic feet per minute) figures are available for specific cabins.
A powerful, three phase electric motor powers the extraction fan.
The overall enclosure is manufactured using galvanised sheet metal with a powder coated finish.
Lasermet provides a full range of laser interlock equipment including control systems, interlock
switches, illuminated warning signs, laser shutters, door locks, external power supplies etc. which
can be connected to provide a complete laser interlock system. Full support, design and installation
is available from Lasermet, please contact us for any queries. Contact details are given at the end of
this manual.

4 Filter
The Lasermet filter assembly has two-stage filtration.
1) EN779 Class M6 Pre-Filter 50mm deep
 Ordering information Lasermet Part Number LMFP-50
2) EN1822 Class H13 HEPA Filter Cell 292mm deep
 Ordering information Lasermet Part Number LMFH-292
4.1 Replacement Schedule
It is recommended that the differential pressure is monitored across each filter stage and the filters
replaced when the first of the following occurs:
1) The M6 reaches final pressure drop 250Pa. The H13 reaches final pressure drop 600Pa
2) Each filter reaches 2.5 times its initial pressure drop.
3) The pre-filter has been installed for 1 year, the final filter 3 years.
4.2 Filter Change
To remove the filter cells, it is necessary to remove the filter access doors. These are secured by
hand knobs so no tools should be required to remove them.
It is recommended the person carrying out the filter change wears appropriate protective
equipment e.g. overalls, dust mask, gloves.
Note: The fan should be isolated from power while the filter change is carried out.
