@pei.liu: Do you know how the wet dust collector with zero consumables efficiently purifies dust? The negative pressure fan draws in dust-laden air, and the water circulation system activates three layers of defense. The water curtain intercepts large particles, the water vortex captures fine dust, and the PP honeycomb panel traps moisture. With three progressive protective layers, the output air is clean and dust-free, with all particles settling into the slag basket. Simply retract the filter belt for easy and efficient maintenance。#DustCollector#enviromental#factory#polish#Malaysia
