Choosing a Location for Dremel LC40
Laser Cutter Operation:
Select a location suitable to accommodate
the selected exhaust management method
from Table 3. Always operate the Dremel
LC40 Laser Cutter in a well-ventilated area.
Do not operate the Dremel LC40 Laser
Cutter in a basement, closet or other
location that is not well-ventilated.
Depending on the installation conditions, a
source of make-up air may be needed to
replace air evacuated by Dremel LC40
Laser Cutter exhaust management system.
For an appropriate make-up air solution,
consult an HVAC professional. Ensure
make-up air source complies with exhaust
discharge requirements below.
The location should provide adequate
support surface for the Dremel LC40 Laser
Cutter and Hex Box. Ensure adequate
space around the Dremel LC40 Laser
Cutter for working access and clearance
for exhaust management system (see
Dremel LC40 Laser Cutter & Hex Box™
Clearance Requirements in Specifications
section on page 9).
Requirements for Exhaust Management
Systems A: Onboard Fan and
B: External Booster Fan
Exhaust discharge requirements
• Discharge the exhaust outdoors where it
will not cause a public nuisance, and not
less than the following distances:
o 10 feet from property lines; 10 feet
from operable openings into buildings
(e.g. windows, doors, air intakes); 3
feet from exterior walls and roofs; 10
feet above adjoining grade
• Protect the exhaust opening using an
Exhaust Vent Hood with a corrosion-
resistant screen or grille (not provided).
Openings in the screen or grille should
be between ¼” and ½” and should be
protected against local weather
conditions. Do not use louvered vent
coverings as they can obstruct exhaust
flow. Install Exhaust Vent Hood
according to manufacturer instructions.
Exhaust duct requirements
• Exhaust ducts shall be UL 181 fire rated
and must be compliant with codes and
regulations for hazardous or noxious
exhaust ventilation systems.
• Ducts must be installed so they are not
damaged or ruptured. Install flexible
connection between Dremel LC40 laser
cutter and any hard duct to isolate
vibration from duct and prevent duct
damage. Up to six inches of provided
Exhaust Hose may be used to create
flexible connection.
• Seal all seams and connections with
building code approved sealant or duct
tape.
• Periodically inspect duct for wear or
damage. If any duct appears worn,
constricted or damaged, replace before
further use.
• Minimize the length of duct and number
of bends/elbows. Ensure duct is properly
supported and complies with relevant
building and fire codes.
• Exhaust ducts must be 4” diameter or
greater. When using duct diameter
greater than 4”, transition to larger
diameter immediately at exit from Laser
Cutter Exhaust Shroud.
• All elbows and/or bends must have bend
radius at least 1.5 to 2 times duct
diameter (Fig. 15) as specified in Setting
up Exhaust Management Method
sections below.
