76 1 AERSERVICE FORNISCE PRODOTTI E SOLUZIONI TENENDO CONTO DI RIFERIMENTI NORMATIVI NAZIONALI E INTERNAZIONALI WELDING AND FINISHING AREA APPLICATIONS MF filter modules were developed for use as filtration systems in centralised systems or individual work stations for the extraction of welding fumes. Given the high level of efficiency of the filters installed in the various modules (rigid bags, electrostatic, and activated carbon), they can be extended also to handle other types of fumes; for example, depending on their composition, these filters can handle welding fumes (also oil-laden), for air treatment in civil plants, to eliminate low concentration of airborne solvent, and for general deodorization processes. Given their compact dimensions, the filters can be installed in confined spaces; in addition, for the smaller AIR CLEANERs they can be installed in suspended solutions to help optimise the use of available space in the workplace. Thanks to the new technologies developed by Aerservice on the application of plug-fans, it is possible to further reduce the size of the system and also significantly reduce costs, by applying an auxiliary module on the filter with dimensions that are proportional to those of the filtration module, thereby obtaining a single element (of sufficiently compact size to allow easy installation) incorporating the functions of filtration and air extraction, allowing the maximum level of dynamic installation and connection to various inlet and outlet ducts. 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.
