Air purifiers are required in a wide variety of applications. Construction sites, renovation sites, clean rooms, hospital rooms, factories, blasting area etc. are few examples. The operating principle is to pass the air through a series of HEPA filters to purify the air. In construction sites and factories, the huge amounts of extremely fine particles pollute the air. While breathing, these particles enter into the lungs of the workers, causing health hazards. We supply a wide variety of industrial air cleaners for these purposes.
