General description of the machine
The portable unit is the ideal solution for the extraction and filtration of welding fumes from variable position
work stations with discontinuous welding operations. The gases and fumes given off during welding are
captured to prevent them from spreading throughout the workplace; the air containing the contaminants is
thoroughly filtered and recycled back to the workplace. This unit is designed for the suction and treatment of
dry fumes produced by work processes such as spot or discontinuous welding wire or electrode welding,
hence involving the emission of low 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 conditions such as occasional or discontinuous use (e.g. 20 hours
out of a 40 hour working week) or in conditions in which the work processes are dynamic to the point at
which a fixed capture system is ineffective. In addition, the filtration unit also purifies the air in the
surrounding environment, thus 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 the filtration sections.
MACHINE CHARACTERISTICS
The portable unit is fitted with a high efficiency suction fan in a negative pressure sound-insulated
compartment which acts as flow calming plenum to reduce the turbulent flow of the treated air before it goes
out through the special output grilles.
The excellent manoeuvrability and highly ergonomic use of this unit ensure it can be utilised in several
different work stations, while the flexible arm is able to operate over a working radius of 3 m.
The machine is supplied as standard with an electrical control panel, IP65 protection, made up of:
-
ON/OFF switch;
-
magneto-thermal protection (for electric motor);
-
differential pressure switch with simultaneous temperature control;
-
machine power supply signal (white light);
-
machine on signal (green light);
-
clogged filter signal (red light).
