Description
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 clinics, waiting rooms.
FOOD SOLUTIONS: Control of air contamination during food processing.
Electrostatic filtration systems are already widely used and tested in civil and industrial environments. Based on the phenomenon of electrostatic precipitation, this type of filtration is characterized by:
1. Very high filtration efficiency, with yields greater than 99%.
2. Contemporary abatement of microorganisms such as bacteria, yeasts, molds and germs.
3. Reliable pressure drop through the filter.
4. The life cycle of the filters is equal to the useful life of the entire unit, with minimal maintenance requirements.
5. Very high level of product reliability.
This allows for a quick recovery of the higher initial investment compared to a traditional filtration system, such as the pocket type, thanks to the reduction in electric consumption of the ventilation sections, as the pressure drop is very low and maintenance costs extremely low since it is not necessary to periodically replace the filters.
Plants characteristics with Electrostatic precipitators (electrostatic filters):
• high efficiency, on the top of E class filtration according to EN 1822 (E10 – E11) till to 2 m/s of speed velocity on the electronic filter;
• low costant pressure drop, compared to the pocket filters currently in use;
• maximum performance linearity (efficiency, pressure drop) during the operative life;
• maximum extension of the operative life (high load capacity in terms of weight of retained pollutants).
These are the basic features, to which is added an extremely important plus: an efficient anti fungal and antibacterial action, in order to avoid the proliferation of bacteria colonies and mold in certain favourable conditions of temperature and humidity, often encountered in typical treatment plants air. For these reasons, and in order to reduce environmental impact, Expansion Electronic has implemented a retrofit’s action that allows you to replace the normal mechanical filters with those of new electrostatic generation one. The advantages are mainly two:
– The lower energy consumption, “energy saving” given by the lower pressure drop and then the re-sizing of existing ventilation fan systems. Thanks to this action is guaranteed a good reduction in CO2 emissions.
– A considerable reduction of the amount of non-recyclable material.
CERTIFICATIONS
Certifications guarantee yields and product performance and are a tool that drives companies to reliable and high-quality choices. To guarantee what said before and to demonstrate once again the reliability and the excellence of Expansion Electronic’s products, our active electrostatic filters were tested by independent and international authorities such as for example the Hygiene Institute of Air ILH of Berlin, Polytechnic of Turin and the Technical Research Institute SP of Sweden. These authorities released the following certifications:
- EN ISO 16890 classifies the air filters on the basis of their ability to retain the dispersed airborne particulate matter (PM10, PM2,5 and PM1) – EN ISO 16890 CERTIFICATION BROCHURE WITH COMPARATIVE TABLES AND FORMULAS
- UL867 is a U.S. standard that relates to the safety of equipment and specifically deals with the Safety of Electrostatic Air Filters. MORE INFORMATIONS
- UNI 11254:2007 classifies the Expansion Electronic filters in four filtration grades (A, B, C, D)
- EN 1822:2005 certfies the Expansion Electronic filters as Absolut Filter, that is class E10-E11
- ILH BERLIN certifies the hygienic and antibacterial effects of Expansion Electronic electrostatic filters that eliminate 99% of molds and bacteria from the air
- Certification of the University of Lucerne certifies the non-release of the particulates and particles captured and deposited on the electrostatic filter if the ventilation unit and / or the filter itself switches off
- Science Partner Swedish technical institute certifies the ozone emissions of our electrostatic filters which are the lowest in the category, that is five times lower than the levels established by the WHO
- Policlinico San Matteo of Pavia certifies the abatement of molds, microbes and bacteria in the air and inside the air distribution channels by the combination of electrostatic filters and negative ionization
- CRN, National Research Council, certifies the reduction efficiency of airborne pollutants between 80 and 100% of Expansion Electronic air purifiers with active electrostatic filter
- CETIAT, Center Technique Des Industries Aérauliques Et Thermiques, certifies the efficiency of the C series purifiers on particles with sizes between 0.5 and 0.8 microns
- BSRIA classifies the air purifiers with active electrostatic filter model Idillium 170 according to the S22/99 specifications.

The machines and plants manufactured by EXPANSION ELECTRONIC are distributed all over the world thanks to its efficient network of distributors. The research into the finest materials and components and the drive towards continuous technological evolution, in order to constantly assure maximum reliability, have generated a number of important references that add value and prestige to our products and our company.
We are very proud of this as it allows us to address the new challenges of the future with optimism and acts as a guarantee for our customers who put their total trust in us.
