2.3 EXHAUST SYSTEM REQUIREMENTS
To properly exhaust fumes and smoke from the laser engraving system during operation, it is necessary
to provide an exhaust unit moving a minimum of 235 CFM at 6 inches of static pressure. Many
industrial supply companies carry blowers that should meet these requirements.
THROUGH OUR RESEARCH WE HAVE ESTABLISHED GUIDELINES ON THE PROPER CFM
RATINGS REQUIRED FOR THE EXHAUST SYSTEM. THESE RATINGS ARE BASED ON THE
MEASURED DISTANCE BETWEEN THE EXHAUST OUTLET ON THE LASER SYSTEM AND
THE INLET OF THE EXHAUST BLOWER. WE HAVE FOUND A SUITABLE SUPPLIER FOR
THIS TYPE OF EQUIPMENT IF YOU CHOOSE NOT TO USE THIS SUPPLIER, PLEASE
ENSURE THAT THE BLOWER THAT YOU PURCHASE MEETS OR EXCEEDS THE
FOLLOWING SPECIFICATIONS.
DISTANCE BETWEEN
BLOWER AND LASER
CFM RATING AT
6 INCHES STATIC PRESSURE
UP TO 7 FEET 235 @ 6 INCHES STATIC PRESSURE
8 - 14 FEET 410 @ 6 INCHES STATIC PRESSURE
15 - 22 FEET 535 @ 6 INCHES STATIC PRESSURE
23 - 30 FEET 625 @ 6 INCHES STATIC PRESSURE
The blower must be mounted on the outside of the building either on the roof or on a cement pad next
to the building. Rigid duct work should be used between the blower unit and the laser system. The
exhaust tubing should be smooth walled and have as few bends as possible. Use duct work with a
diameter that matches the blower unit and reduce the duct work to four inches just before the point
where it attaches to the laser system. Also consider installing a gate to control air flow and to close off
the exhaust from the outside environment when the laser is not in use. This is especially useful in colder
climates where it is not good to have cold air coming into the laser from the outside. Do not connect the
rigid duct work directly to the laser system. Use a short piece of industrial grade, wire reinforced
rubber tubing to connect the end of the gate, or tubing, to the laser system. This will provide mobility
and will dampen blower vibrations. Do not use a very long piece because it’s spiral construction
reduces air flow. Install a hose clamp on both ends of the hose to prevent leaks and to prevent the hose
from slipping off.
Having the blower wired to a wall switch in the same room will make it easy to turn it off and on.
WARNING
Do not attempt to operate the laser engraving system without a properly installed and
operating exhaust system. Some materials when cut or engraved can produce fumes
that are hazardous in concentrated amounts.
