Gases and fumes generated by laser
machines are hazardous to your health. It
is your responsibility to install a dedicated
and rated fume extractor if toxic gases or
fumes are produced during laser cutting
operations.
Dust and embers from laser machines pres-
ent a fire hazard. DO NOT direct exhaust
ports anywhere combustible materials exist,
or combine laser extraction fan with wood-
working dust collection systems.

Water Chiller
Overview
During operation, water is circulated through the
laser tube cooling chambers. As the water flows
through the laser tube, it absorbs heat along the
way. The returned water dissipates heat through
a refrigerant-cooled radiator before returning to
the reservoir and being cycled through the laser
tube again.
The water temperature must be kept below 122ºF
(50ºC) and above 50ºF (10ºC) or the water chiller
will sound an audible alarm and suspend circulat-
ing water. If an overheat alarm occurs regularly,
a larger water chiller system may be required, or
a refrigeration-type water chiller may have to be
installed in environments susceptible to extreme
heat. To prevent water from freezing, add 50/50
non-corrosive anti-freeze to water chiller reservoir.
IMPORTANT: Always use anti-freeze that is listed
as non-corrosive to prevent water hoses from pre-
maturely deteriorating.
Air Pump Overview
Laser cutting operations require an air nozzle to
focus a jet of air that blows fumes, smoke, dust,
and other materials away from the laser beam
focal point. This jet of air also prevents combus-
tion by continuously cooling the area and limiting
fuel at the source of ignition.
During operation, air enters the rear of the pump
through a barbed-fitting on the filter cover. The
air passes through a washable-foam air filter, and
exits out of a metal barbed fitting at the front of
the pump. The air then travels through a hose to
the AIR IN fitting on the auxiliary systems connec-
tion panel, before continuing on to the laser beam
focal point.
Extraction Fan
Overview
The extraction fan is a simple centrifugal-type fan
that blows a large volume of air away from the
machine when operating.
During operation, the extraction fan creates a
negative-airflow vacuum in the machine interior,
which extracts smoke and particulates from the
worktable down through the lower cabinet and
exits the machine via the exhaust ducting.
