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
