Acid Fume Scrubber

Product Description

The acid fume scrubbers or fume scrubbing system remove chemical mists and droplets from the exhaust air. These acid fume removal scrubber has high chemical removal rate and so it helps in avoiding the discharge of hazardous fumes that might harm the workers and corrode equipment.


he contaminated air is exposed to the chemical solution. The chemical solution reacts with the air and the pollutants in the air gets neutralized. For efficient operation of the acid fume scrubber, the acid fumes must be exposed to large surface area of the neutralizing solution. The fumes pass over a wet packed bed. The packing material surfaces are covered by the neutralizing solution resulting in a removal rate for the fume chemicals that can reach 99 percent.

The air flow capacity of the acid fume scrubber ranges from 500 to 25000 CFM and it requires very less water consumption. Acid fume scrubber is constructed of black polypropylene with is UV protection and are built with double contaminant for more safety and a drain is provided at the bottom for the easy maintenance.
