Although the catering smoke exhaust system belongs to high-power equipment, it still consumes less electricity in a day. The kitchen fume purifier looks very big, but in fact, the components inside do not need to move, and it will not emit light and heat. It mainly produces high and low voltage static electricity, and absorbs oil fume particles through electrostatic force. So its power consumption is generally not very high.

Of course, if you count the fan, the power consumption of the fan with 4000 air volume may be greater than that of the lampblack purifier.
