FE SYSTEM: air filter in energy class A+ that is constant over time

CONTENTS Introduction Carachteristics of EN ISO 16890 Advantages of EN ISO 16890 Comparison for the classification of the filters EN 779 vs EN ISO 16890 Energetic comparison Pocket filter vs electrostatic filter Evaluation of energy consumption KEP: Key Energy Performance Conclusion

INTRODUCTION The introduction of the new global standard UNI EN ISO 16890, which classifies the air filters on the basis of their ability to retain the dispersed airborne particulate matter (PM10, PM2,5 and PM1), is generating a general revolution in the air filtration sector. It replaces the previous and obsolete EN 779:2012 standard (F7, F8, F9), anti-dust air filters for general ventilation. The table 1 shows the classification on the different particulate dimensions according to the new standard. 1. It replaces an existing standard from more than 20 years. 2. The efficiency refers to...

ADVANTAGES OF EN ISO 16890 1. The filters will be more suitable for the real conditions of the desired application. 2. Easier to correlate with international organizations such as WHO (World Health Organization) thanks to the same nomenclature. 3. Possibility to calculate in an engineering way a filtration system. 4. Improvement of the Indoor Air Quality. 5. The norm will be valid worldwide. The main difference between the previous EN 779 standard and the new EN ISO 16890, for the users, lays in the classification system of the HVAC filters efficiency. In order to be classified as PM1,...

r>y expansion Kl/ electronic COMPARISON FOR THE CLASSIFICATION OF THE FILTERS EN 779 VS EN ISO 16890 In the EN 779 standard, the efficiency towards coarse and fine powders was based on particles with an aerodynamic diameter of 0,4 pm. In the ISO EN 16890, the efficiency is defined on the basis of particulate having different dimensions: PM10, PM2,5 and PM1. Table 3 *potassium chloride

ENERGETIC COMPARISON POCKET FILTER vs ELECTROSTATIC FILTER With the new UNI EN ISO 16890, the FE SYSTEM electrostatic filter of Expansion Electronic is the only air filter with energy classification A+ that is real over time.

EVALUATION OF ENERGY CONSUMPTION Formula of energy cost in relation to pressure drop E= q: air flow (m3/s) Δp: avarage pressure drop (Pa) t: work time (h/year) n: efficiency / performance Pocket filter Comparing an electrostatic filter with a pocket filter of equal efficiency, we can see that the annual energy consumption of the pocket filter is 3 times higer.

kep: Key Energy performance An additional indicator of filters performance is the KEP (Key Energy Performance) related to Energy Performance. The KEP is an indicator that represents the goodness of a filter. The higher the indicator is, the lower the environmental impact of the filter will be. ePMx: certificated efficiency of the filter (ePM1=70% = 0.7) Δp: average pressure drop Cx: constant = 35 Pa Electrostatic filter FE SYSTEM Pocket filter

The medical-scientific community also recognizes the problem about micro-particulate and is paying special attention to PM 1, which is considered the most dangerous fraction of PM for human health. This new standard will therefore lead to an improvement in indoor air quality for the benefit of the health and wellbeing of people and production processes. Thanks to their properties, the active electrostatic filters of Expansion Electronic offer very low pressure drops, constant during normal operating life. When the maximum degree of dirt is reached, the electrostatic filter can be maintained...
