Fractional Efficiency and Pressure Drop - Electrostatic Precipitator
The red curve in the diagram show filtering efficiency versus air velocity for the particle sizes 0.3 µm - 5.0 µm*.
The black curve represents the pressure drop as a function of air velocity.
*) The CTA Electrostatic filter was tested at SINTEF, Norway in 1994 according to ASHRAE 52-76,
Eurovent 4-5, DOS and Atmospheric air.
