How Does an Industrial Fume Purifier Work?

2026-04-28

Industrial fume purifiers, particularly electrostatic precipitators (ESPs), are highly effective at removing oil mist and smoke from exhaust streams. The process begins as the fume-laden air passes through a high-voltage ionization section. Here, an electric field imparts a positive charge onto the oil and smoke particles. Next, the air flows through a collector section, which consists of a series of parallel plates with an opposite electrical charge. These plates attract and capture the charged particles, removing them from the air stream. The clean air is then discharged, while the collected oil can be drained away. This technology provides high-efficiency purification (over 95%) with a low pressure drop, making it ideal for commercial kitchens and industrial applications.
