SETUP
• Use low-pressure drop vent louvers
Typically found on clothes dryers and
bathroom vent fans.
Exhaust system configuration example
using the DigiLAB internal exhaust fan.
When using the internal exhaust fan w/
blower assistant, be sure to choose
correct ventilation option on the LCD
during the laser startup sequence.
Recommended features for an
exhaust vent hood:
• IMPORTANT: Choose a single,
lightweight louver/damper which
requires minimal exhaust duct flow to
open.
• Wide mouth anti-gust hood design.
• Damper prevents back-flow of exhaust
air.
• Screen/grate to keep out birds and
rodents.
• Always use rigid or flexible metalized
duct tubing. Never plastic. Plastic box
hood and louvered hood sections are
acceptable.
• Always use the supplied flexible
metalized duct. If additional duct is
required, it must meet Underwriters
Laboratory specification UL181.
• Rigid metal duct tubing can be used
but, all seams must be sealed with foil
tape.
• Semi rigid duct is not recommended
because of the potential for fume leaks
along the spiral crimp.
Use Case 2: The unit will use a secondary
standalone portable filtration system:
Before setting up and
operating the Portable
Filtration System, read the portable
filtration system instruction manual.
Set-up with Portable Filtration System:
Choose a well ventilated area to set-up
the Digilab Laser and portable filtration
system.
If you have purchased the Digilab Laser
Bundle with the filtration system or if you
have purchased another Portable
Filtration System, follow the instructions
below:
Read the instruction manual of the
supplied filtration system to properly set
up the filtration system unit.
Multi louver ducts
