Exhaust 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 200 CFM (cubic feet per
minute) at 6 inches of static pressure (inches of water)
. Please refer to the sample diagram
on the next page.
The blower
MUST
be mounted on the
OUTSIDE
of the building either on the roof or on a
cement pad next to the building possibly mounted on vibration dampeners. Rigid tubing should
be used for 90% of the distance traveled. The tubing should be smooth walled and have as few
90 degree bends as possible. Two 45 degree bends have better air flow than one 90 degree
bend. Use tubing with a diameter that matches the blower unit (usually 6 inches/1524 mm) and
use a 6 inch(1524 mm) to 4 inch(1016 mm) reducer to couple the tubing down to 4 inches(1016
mm) to within a few feet from 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 can be damaging to the laser system to have cold
air coming into it from the outside. Do not connect the rigid tubing directly to the laser system.
Use a short piece of industrial grade, wire reinforced rubber tubing to connect the end of the
gate, or rigid tubing, to the laser system. This will provide mobility and will dampen blower
vibrations. Use only a few feet 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.
Have the blower wired to a wall switch in the same room.
The chart below is based on the measured distance from the outlet of the laser system to the
inlet of the exhaust blower. It assumes that you will. It is important to purchase a high pressure
blower that meets or exceeds these requirements.
Measured Distance
Blower Required
up to 25 feet / 8 meters
200 CFM @ 6 inches / 1524 mm static pressure
26 - 50 feet / 8 - 15 meters
300 CFM @ 6 inches / 1524 mm static pressure
51 - 75 feet / 15 - 23 meters
400 CFM @ 6 inches / 1524 mm static pressure
76 - 100 feet / 23 - 30 meters
500 CFM @ 6 inches / 1524 mm static pressure
Never 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.
The following diagrams show typical exhaust system layouts. Use these as a guideline to
proper exhaust system installation. Although these diagrams just serve as an example, we
recommend installation of the exhaust system by a licensed contractor to meet safety and local
code requirements. Please contact a local air quality control specialist.
