The major advantages of electrostatic precipitators are that high collection efficiencies can be achieved even with small particles and the pressure drop across the precipitator is low. the latter characteristic makes precipitators especially attractive when large gas volumes are to be handled.
Electrostatic precipitators esps can handle large volumes of air without significantly slowing down the rate of flow, because of the low pressure drop across the electrostatic filter. kitchen extraction air is a tricky target, due to the complex mixture of grease, smoke, water vapour and temperature.
Electrostatic filtration is a wellknown technology that uses high voltage and ionization fields to capture particles from the air flow, aka electrostatic precipitators esp. esps bases its functioning on electric fields and electrostatic forces applied directly on particles and on microorganisms present in the air.
