ELECTROSTATIC FILTER FE SYSTEM

Product catalog summary

Introduction
The document discusses the FE SYSTEM electrostatic filters designed for indoor air quality improvement with low energy consumption. These filters are certified according to EN ISO 16890 and UL867 standards, ensuring high safety and efficiency in air filtration.

Specifications
The filters are available in standard dimensions compatible with pocket filters and feature an incorporated electric circuit that is waterproof and can be cleaned with water. They support a multipolar connection for network supply and have a self-centering system to accommodate manufacturing tolerances.

Performance
The FE SYSTEM offers high-efficiency filtration for particles as small as 0.3-0.4 microns, comparable to classes E10 and E11. It effectively reduces bacteria and viruses in the air and protects heat exchangers and air pipes from pollutants.

Energy Efficiency
The system provides significant energy savings due to low air-flow resistance and maintains constant filtration efficiency up to a 600g fine particle load. Compared to traditional pocket filters, it has a lower initial pressure drop and slower increase in pressure drop over time.

Applications
The filters are suitable for use in air handling units and rooftops across residential, tertiary, and industrial fields, including hospitals and agro-alimentary sectors. They are particularly effective in controlling airborne contamination in various environments.

Installation and Maintenance
The FE SYSTEM is easy to install and maintain, with a simple slide-in and out mechanism for the filter units. The filters are regenerable and can be washed and reused, extending their lifespan significantly.

Technical Data
The document provides detailed technical specifications, including energy consumption, accumulation capacity, air flow capacity, and dimensions for various models. The filters are classified according to multiple standards, ensuring compatibility and performance.

Conclusion
The FE SYSTEM electrostatic filters offer a reliable and efficient solution for improving indoor air quality while minimizing energy consumption. Their ease of installation and maintenance, combined with high filtration efficiency, make them a valuable addition to any air handling system.

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 determines the new classification of filtration for “air filter...

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 systems in general, and more specifically in the air conditioning plants, does not imply any variation regarding constructive and dimensional characteristics of the plants themselves. 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...

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,...

ANTIBACTERIAL EFFECT 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. Measurement...
