Since 1917, The Clean Air Group, LLC has been driving performance in the air pollution control industry with the strength, experience, and staying power that only a true legacy company can claim. With over 100 years of engineering heritage and successful installations, we are known for tackling complex industrial emissions challenges head-on with proven, high-performance solutions. When the application is demanding, the chemistry is aggressive, and failure is not an option, customers turn to CR Clean Air.
CR Clean Air is recognized for expertise in ethylene oxide, hydrochloric acid, sulfuric acid, and nitric acid scrubbers, along with packed towers, Fiberwind™ candle filters, wet electrostatic precipitators, nitrogen generation systems, and thermal oxidizer support. These applications demand strong command of mass transfer, reaction chemistry, mist elimination, particulate capture, corrosion control, and material selection for long-term reliability.What sets CR Clean Air apart is an application-driven engineering approach. We do not force standard equipment into nonstandard duty. Our systems are developed around actual process conditions, contaminant loading, gas composition, temperature, hydraulics, site constraints, and maintenance requirements. The result is equipment that is more reliable, more maintainable, and better matched to real operating conditions.With a legacy dating back to 1917 and a global installed base, The Clean Air Group, LLC brings proven field experience across retrofits, replacement units, system expansions, and new installations. Our engineering focus includes absorber sizing, packing selection, gas-liquid contact efficiency, pressure drop, residence time, mist control, and metallurgy. We evaluate each application against process chemistry and operating risk, so the selected system is practical to install, operate, and support over the long term.
