Dust is not the only air pollutant. Corrosives, VOCs, NOx, SOx, and Hg, pose pollution problems that need to be controlled. IAS offers fully engineered and turnkey air pollution solutions for these contaminants. Additionally, in an industrial ventilation system, the fan tends to be the noisiest component. Therefore, we provide several strategies for reducing unwanted fan noise: inlet and outlet silencers, acoustical blankets, and full acoustical enclosures.
