DETAILS The use of static air filtration dates back to the early 1900s, when a newly patented device in the United States was employed for the abatement of fumes which came from a sulfuric acid synthesis system. OPERATION PRINCIPLE Thanks to the specialization in different applications and to the evolution of materials and control systems, this principle is now available in many constructive variants of different complexity, which are intended for specific applications such as air treatment and air conditioning (shopping centers, hospitals, offices), or in the food, textile, mechanical or...

MAIN CONSTRUCTIVE FEATURES The FE SYSTEM series consists of a new range of active electrostatic filters, very practical and usable in substitution or in addition to traditional mechanical filters (bag and pocket filters), in new and /or existing installations without adaptation costs. FE SYSTEM electrostatic filters are made up of a metallic aluminum body, which, during the filtration process, intercepts the pollutant by accumulating it on the capture blades. Its adoption in ventilation systems and in particular in the air conditioning industry does not require changes in the structural and...

MAIN CONSTRUCTIVE FEATURES 1 - ADAPTABLE One of the main features of the FE SYSTEM Filters is the applicability in a variety of industries thanks to the standard sizes compatible with the pocket filters. AIR CONDITIONING: Installation inside conditioning units for residential, tertiary and industrial sectors. INDUSTRIAL: Filtration of micro dusts, rubber and plastic fumes, fumes in general, welding fumes (such as ferrous metals, precious metals, control panels) with a maximum concentration of 20 mg/m. HOSPITAL: Control of aerodynamic contamination for hospital rooms, white rooms, outpatient...

3 - INCORPORATED ELECTRONIC Circuit A feature that distinguishes the FE SYSTEM Filters is the built-in electronics that generates the high voltage needed for the operation of the filter. Led Multi-pole connectors can be used to connect multiple filters with one power line (230V to 50Hz) and provide the alarm signal. Integrated electrostatic circuit with complete watertightness. 4 - CERTIFICATED EFFICIENCY The FE SYSTEM filters have been tested by independent and international organizations, which have issued the following certifications: UNI 11254 : 2007 EN 1822 : 2005 EN 779 : 2012 It...

FILTRATION EFFICIENCY I filtri elettrostatici “bitensione” presentano un’elevatissima efficienza di filtrazione, legata anche alla velocità di attraversamento come riportato nella figura seguente. The “dual-voltage” electrostatic filters have very high filtration efficiency, also linked to the crossing speed as shown in the following figure. TABELLA 1: EFFICIENZA FILTRAZIONE a 1m/s e 2m/s FE600 Table 1: Filtration efficiency 1m/s and 2m/s FE600 L’efficienza di filtrazione è dunque non inferiore a E10 (ex H 10) ovvero la classe The filtration efficiency therefore not less than E10 (ex H10),...

ECONOMIC ANALYSIS High performances of electrostatic filters are accompanied by important benefits mainly due to: • Pressure drop on the airflow side is absolutely modest, determined almost exclusively by the metal prefilters G2 or G4. This results in a significant reduction in the energy consumption for ventilation, with the filtration efficiency that stays constant throughout the operating cycle; • The life cycle of the filters is equal to the life of the machine itself (15-20 years): the soiling of the electrostatic filter is signaled by a sensor that allows to program its periodic...
