Is It Normal For A Newly Installed Electrostatic Precipitator To Keep Making Crackling Noises?

Jun 10, 2025

The "crackling" noises of an electrostatic precipitator are abnormal. The reasons are as follows:

The "crackling" noises of an electrostatic precipitator are abnormal. The noises are caused by too much water vapor inside the purifier or too much particulate matter entering. When the electrostatic precipitator keeps making crackling noises, the electric field of the purifier cannot purify the oil smoke, and the oil smoke will be discharged directly from the purifier.

If the electrostatic precipitator keeps making "crackling" noises, it is recommended to contact after-sales service as soon as possible, otherwise the power supply may be burned out, and even cause a fire in serious cases.

Environmental protection is very strict now. It is recommended to clean and maintain the electrostatic precipitator regularly to ensure the purification effect, so that the exhaust oil smoke can pass the inspection.

So under what circumstances is it easy for an electrostatic precipitator to make "crackling" noises? Generally speaking, there are several situations:

1. After the electric field is cleaned, it is not dried and there is too much water vapor.

2. The high-voltage power supply of the electrostatic precipitator is adjusted too high.

3. The particles entering the electric field of the electrostatic precipitator are too large.

4. The insulation of the electric field of the electrostatic precipitator is broken down.

All the problems can be roughly classified into the above four reasons. If you encounter the above situation when using the electrostatic precipitator, it is recommended to contact the purifier manufacturer and let professionals handle it.
