104 1 AERSERVICE FORNISCE PRODOTTI E SOLUZIONI TENENDO CONTO DI RIFERIMENTI NORMATIVI NAZIONALI E INTERNAZIONALI APPLICATIONS The FACE mobile 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 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 and, especially, oil-contaminated 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 a fixed capture system is ineffective. In addition, the air cleaner 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 the filtration sections. WELDING AND FINISHING AREA 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.

105 Equipments TROLLEY-MOUNTED AIR CLEANER WITH ELECTROSTATIC FILTRATION CONSTRUCTION FEATURES • Self-loading structure in powder painted sheet steel, complete with wheels and handles, and featuring dimensions and weight such as to allow easy manoeuvrability and ergonomic use. • High-efficiency centrifugal fan located downstream of the filter section in a specific sound-insulated compartment. • Plenum created within the overall dimensions of the unit to calm the airflow and decrease the velocity at which the airflows through the filters, thus producing the maximum filtration efficiency and reducing...

106 FACE ADDED VALUES Structure in powder coated steel, with flow calming plenum to reduce the airflow velocity and noise levels. Soundinsulated SUCTION fan mounted on board the unit, with low power consumption and low noise emission. Extracts and returns to the workplace the same quantity of air, thereby eliminating the need for forced replenishment of the air. The air surrounding the site of the work process is cleaned and changed. Electronic device of the latest generation with filter loading and incorrect phase sequence (phase sequence relay) indicators supplied as standard on all models....
