Common problem faced in Conventional HVAC systems
The most innovative and effective solution to overcome the limitations of conventional clean room HVAC systems is to use Filter On Electrostatic Precipitator (ESP) type Filtration Systems.
The technology is based on the principle of two stage electrostatic air filtration. Fine sub-micron suspended particles are electrostatically charged using high-voltage electric field, which then get attracted and precipitated on opposite charged electrode plates.
Technological advantages :
Filter On Electrostatic Filtration Systems offer high efficiency even for small submicron particles which form the maximum percentage of floating and suspended particles in air. The efficiency of ESP is equivalent to or rather better than EU9 grade filters.
As compared to any type of filter having EU9 equivalent filtration efficiency, ESP offers very low pressure drop i.e. only 6-12 mm WG.
Since ESP is made of Aluminum plate electrodes, it never requires any replacement over the lifetime (15-20 years). It only requires periodic cleaning. So, no replacement costs at all.
Filter On M-03 model of required capacity can be introduced as a pre-filteration unit either at fresh air intake end or can be attached to the AHU in the mixing chamber.
