WELDING AND FINISHING AREA
APPLICATIONS
The FACT portable unit constitutes the ideal solution for extraction and filtration of welding fumes from variable
position work stations with discontinuous welding operations. The gases and fumes given off during welding are
aspirated and treated to prevent them from spreading throughout the workplace; the aspirated air containing the
contaminants is thoroughly filtered and recycled back to the workplace. This unit is designed to aspirate and treat
dry fumes produced by work processes such as spot or continuous wire or electrode welding, hence involving the
emission of medium-high concentrations of pollutants containing gas or suspended welding slag.
National and international regulations allow the use of these devices in replacement of conventional air cleaners
with an articulated arm in special situations such as occasional or discontinuous use (e.g. 20 hours out of a 40
hour working week) or in situations in which the work processes are dynamic to the point at which the use of a fixed
capture system is impractical. In addition, filtration unit also purifies the air in the surrounding environment, so not
only treating the area contaminated by the work process but simultaneously creating air exchange in the workplace
and further decreasing the level of pollutants present. To comply with regulations and to obtain high quality filtration
with consequent safety for the operator, it is essential to perform correct maintenance/periodic replacement of
the filters, which, in our units, provide high capacity for accumulation of contaminants and very low costs for spare
parts of the filtration section.
AERSERVICE SUPPLIES PRODUCTS AND SOLUTIONS TAKING ACCOUNT
OF NATIONAL AND INTERNATIONAL NORMATIVE REFERENCES
OPERATOR SAFETY
Pollutants deriving from industrial and small
workshop processes must be captured as
close as possible to the point of release and
routed to the exterior of the workplace. In
the case of intermittent work processes
however, such pollutants can be aspirated
and filtered out of the air, which is subsequently
returned to the workplace. In this
case, in addition to the use of portable air
cleaner systems the installation of ambient
ventilation systems may be required. Italian
decree D.Lgs. 81/2008 - 2006/15/EC
TECHNOLOGY EMPLOYED
To guarantee and satisfy the applicable
national and international standards
and regulations, we make use of the
best available technology, which, combined
with superior technical know-how,
results in the creation of safe products
that are in compliance with the people
responsible for using the equipment;
for example, the speed of capture of
the pollutant is never considered at
less than 0.5 m/sec during the design
stage (as required by the controlling
authorities).
ENVIRONMENTAL ASPECT
The filtration performance levels guaranteed
are established in accordance
with international specifications that
limit the concentration levels of airborne
pollutants for professional activities
for which a repeatedly exposed worker
does not suffer any form of health
impairment. American Conference of
Industrial Hygienists (ACGIH) – Italian
decree D.M. 20/08/1999. National
and international regulations are referred
to the values specified by ACGIH.
