Introduction to ESP
Electrostatic Precipitators or ESPs work by ionizing and trapping grease and smoke particles onto collector plates. They have a high particulate removal efficiency, removing sub-‐micron particles as much as 99.5%. Exhaust air flows through two sets of ionizer cells and collector plates to ensure maximum efficiency. A significant advantage of ESPs is the low pressure drop which means that existing fans do not need to be upgraded.
Three Stages of Filtration
- Stage 1 : Media Pre-‐filter designed to arrest small particulate (Grade EU4).
- Stage 2 : Electrostatic collector removes sub-‐micron particles such as smoke, grease particles and are 95% effective
- Stage 3 : Aluminium Post-‐filter
