SECTION 2: GETTING STARTED
3. Connecting the Exhaust
In this manual, the term "exhaust" refers to either an exhaust fan or a filter unit and the term "exhaust"
is used for simplicity. The important point is that it is mandatory that an exhaust unit or filter system is
incorporated as part of your laser system. Never operate your laser system without a properly functioning
exhaust. The exhaust removes the dust, debris and smell from the engraving cavity and exhausts it to
the outside of the building or to the filter unit. Prior to the installation of the laser system, you may need
a contractor to install the exhaust system. The blower should be mounted outside your building for noise
considerations. Ideally, the blower should not be more than twenty feet (6 meters) from the laser. You
should provide a metal duct (flexible aluminum or galvanized sheet metal) from the blower to the laser.
All Epilog model 16000 laser systems require an exhaust fan that is rated at a minimum of 800 CFM for
external exhaust.
The exhaust requirements for the Fusion Pro 32 and 48 are the same:
•
The Fusion Pro 32 model requires 400 CFM for the primary exhaust port (upper port) and 400 CFM for
the downdraft exhaust port (lower port) totaling 800 CFM.
•
The Fusion Pro 48 model also requires a total of 400 CFM for the two primary exhaust ports (200 CFM
per upper port) and 400 CFM for the downdraft port (lower port) totaling 800 CFM.
Epilog provides recommended exhaust flow rates (CFM) only for direct ventilation exhaust systems
that are ported to the outside. Please note that this is also a recommendation and not a requirement,
because factors such as length and type of tubing from the Epilog laser to the exhaust fan and from the
exhaust fan to the outside of the building can produce significant losses on the true amount of air that
is drawn from the Epilog laser.
Exhaust flow rates (CFM) for filter systems are not specified in this document. However, exhaust flow rates
for filtration units will be lower than a direct ventilation exhaust systems because filters are designed to
be placed directly adjacent to the laser system and do not exhibit the air-flow losses that are typically
found with direct exhaust fans. Epilog has worked with most major filter manufacturers to recommend a
specific filter system for each model of Epilog laser. Please contact your Epilog distributor to match a
filter to the Epilog laser system you are using.
Note: Remember to put the blower switch for the laser system in an obvious and accessible
place so it can be routinely switched on prior to using the engraver. Please connect the
exhaust blower to the laser as shown below and on the following pages.
Remember, you may need a contractor to install
the exhaust. This must be done PRIOR to
installation of the laser system.
Warning: It's important that either
rigid or flexible metal ducting be
used for all connections leading to
and from the laser system and the
exhaust fan. Vinyl, plastic, or any
type of "soft" ducting is potentially flammable
and should not be used unless provided by the
filtration system manufacturer and made from
fire-proof materials.
