Connecting The Exhaust - Epilog Fusion M2 32 Manual

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 13000/14000 laser systems require an exhaust fan that is rated at a minimum of 650 CFM for external exhaust.
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.
