ELECTROSTATIC FILTER Indoor Air Quality with low energy consumption

expension* t/ electronic BETTER AIR FOR A BETTER QUALITY OF LIFE Since 1981 Expansion Electronic designs and manufactures machines and systems to treat the air with electrostatic filtration technology. Recently the company has developed a new filter with incorporated electronics for the indoor air quality, which will immediately find a variety of applications. The patented system is named with the initials of electrostatic filtration, indicating the birth of a new standard in this field. FE SYSTEM PATENTED The electrostatic filters FE SYSTEM have been certified according to EN ISO 16890, which...

EASY INSTALLATION The electrostatic filter FE SYSTEM represents an alternative to the common pocket filters and it is conceived to simplify the usage of electrostatic filters in AHU (Air Handling Unit) and Rooftop. Its adoption within ventilation plans in general, and more specifically in the air conditioning plans, does not imply any variation regarding constructive and dimensional characteristics of the plan. Thanks to its multipolar connection system, assembly and disassembly FE electrostatic filters become simple, it is enough to slide in and out the filtering units inside the support filter...

ENERGY SAVING In the active electrostatic filter FE SYSTEM, the initial pressure drop increases slowly while the filter gets dirty. This characteristic, combined to an extraordinary capacity of pollutants accumulation, allows the filter to have a long operation time between maintenance and the other one. In a traditional pocket filter the initial pressure drop is higher than in a FE SYSTEM, and it increases considerably during its clogging. The pocket filter must be replaced when it reaches the maximum pressure drop of 300 Pa. Comparing the FE SYSTEM with two other different filtering systems,...

The electrostatic filter has an elevated antibacterial power thanks to its high collection efficiency of submicronic particles, then also because of its strong electric field force. In the Test A it has been measured the concentration of some bacteria commonly present in a given ambient air, before and after the electrostatic filter. The efficiency is between 98 and 99,9%. Test B shows how the concentration of moulds in the air gets reduced when the ambient is equipped with an electrostatic air filter. Bacterial colonies growing on a plate exposed to the air.
