Wet Dust Arrestor

The Dustair wet arrestor is a highly efficient wet scrubber / dust collector made in sizes standard varying from 1,000 cfm to 20,000 cfm and above to suit specific applications. The basic operating principle is a simple and yet well proven system utilizing the negative pressure of the fan to induce a water spray through the internal scrolls of the wet collector. The result that this gives is a highly efficient water scrubbing system, but without the inherent problems of pumps, pipework or spray nozzles. This means that the unit is relatively self cleaning on many dusts and requires very little maintenance. The system is also very simply engineered to provide good facilities and access for any maintenance and cleaning arrangements that may be required. The scrubber cleans the air by driving the dust laden atmosphere into a plenum chamber, then forcing it at high velocity through narrow slots. This picks up water through heavy turbulence created at the narrow scroll orifice. Additional centrifugal force is then applied to the air path to induce constant wetting of the dust before this is finally trapped and thrown back to the clean side of the filter for settling. The efficiency of the system is maintained by a water levelling device which requires very simple setting initially and then no further modification is required.
