The ambient air in clean air rooms needs to be constantly monitored for the safety of workers and of the production according to the environment. A clean air room is a room where the concentration of particles is controlled in order to minimize the introduction, the generation, retention of particles inside, for instance for chip production or the production of medicines.
The semi-conductor, circuit board and electronics industry have multiple applications for air pollution control equipment from the control of cleaning solvents and acid gas to the capture of particulate matter.
The Clean Air Group, LLC has provided many scrubbers (venturi type, ejector type, packed towers) for the chemical plant area of refineries. These have treated pollutants such as elemental sulfur, maleic anhydride, pthalic anhydride, ethylene oxide, hydrogen sulfide, etc. Our venturi scrubbers can be effectively utilized to handle the off-gases from FCCUs. Other specialized applications (for instance using Stretford Solution in an Ejector scrubber for high efficiency H2S removal) are not unusual for Clean Air...
The primary metals manufacturing industry includes iron & steel production. A variety of clean air solutions are required for capturing, conveying, and collecting emissions from steel rolling mills, including fume exhaust, ventilation and process cooling systems. The iron & steel industry also requires technologies for product recovery, along with dampers and expansion joints, and pumps and valves.
The chemical process industry has been the Clean Air Group, LLC primary market since the Company’s inception in 1917. Our experience with a multitude of chemicals and processes is the foundation of the Clean Air Group, LLC expertise in wet scrubbing. Clean Air Group, LLC broad experience runs from the treatment or relatively simple acid gases to exotic and severely toxic substances including NaCN, HCN, Phosgene and Arsine.
The manufacture of fiber optics involves the integration of various metal compounds to assist with the refraction of light within the fiber. Production of fiber optics create gaseous and sub-micron particulate emissions that are extremely valuable to recapture. A major fiber optic manufacturer has purchased multiple scrubber systems from the Clean Air Group, LLC to not only meet air emission standards but to capture this valuable product. Not only has the Clean Air Group, LLC APC system reduced the customer’s...
A variety of refining and gas field sweetening scrubbing applications have long been a staple application. The Clean Air Group, LLC has been recognized as a preferred vendor for a leading refinery process licensor for the FCCU regeneration gas effluent clean-up. Here, particulates and HCl and Cl2 corrosive gasses are effectively scrubbed at ultra high temperatures, protecting downstream equipment.
Odor control via the use of oxidizing reagents can be effectively accomplished using the Clean Air Group, LLC counter current packed towers. Whether it is H2S, NH3, both or other odorous compounds we have the scrubber technology or absorber technology to satisfy treatment needs.
The primary metals manufacturing industry includes aluminum production. A variety of clean air solutions are required for capturing, conveying, and collecting emissions from aluminum rolling mills, including fume exhaust, ventilation and process cooling systems. The aluminum industry also requires technologies for product recovery, along with dampers and expansion joints, and pumps and valves.
Focuses on low NOx and NOx-related concentrations up to 100 ppm where high resolution is required. Parameters included are NO, NO2, NOx and NOy. Target applications are ambient air monitoring, indoor measurement, clean room measurement and atmospheric research.
The TunnelTech 101 Visibility Monitor (VIS), is an essential part of any road or rail tunnel safety system. It monitors the Visibility within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air for drivers to clearly see the road ahead. The TunnelTech 102 Cold smoke monitor (CSM detects smoke from a fire to rapidly warn the operator of the hazard. Secondly, used in combination with other TunnelTech 101 VIS monitors, the operator can quickly detect the locus of the fire if it is...
Managing overall environmental control is essential for electronics manufacturing processes and operations as well as facilities like battery dry rooms that provide mission critical low dew point conditions.

Sterilization of medical instruments is required in the medical community. Either oxidizers or scrubbers have been used to control Ethylene Oxide (EtO), a gas typically used in the sterilization process. The Clean Air Group, LLC has become the recognized leader in EtO scrubbing with numerous installations at various sterilization facilities. Medical waste incinerator flue-gas treatment is another area of the Clean Air Group, LLC expertise.
The Clean Air Group, LLC has provided multi-stage scrubbing packages to most of the top multi-national pharmaceutical companies for both production process and pilot pharmaceutical process off-gases. These specialized systems are design to accommodate wide variations in operating conditions and many different pollutants. The Clean Air Group, LLC has provided venturi scrubbers for particulate removal and packed towers for water soluble VOC removal from tablet making processes.
Applications in pulp and paper include controlling particulate and VOC emissions from particle board production; sub-micron ammoniated compounds control; sulfur based emission controls; thermal oxidizer pretreatment; and acid mist control. Scrubbers are extremely effective with high removal efficiencies at low pressure drops. Additionally, the Clean Air Group, LLC supplies counter current packed towers for TRS removal, odor removal, Cl2 and ClO2 treatment.
Pelletsare typically manufactured from wood chips and sawdust. The wet raw material in usually grinded in a hammer mill and then dried in a rotary dryer heated by a biomass furnace. The material is then collected in dryer cyclones to be pelletized. The air conveying the wet grinded material is cleaned with a particulate filter before going to the atmosphere. A common type of filter used for this application is the cyclo-filter, which combines the operating principles of cyclones with a cartridge filter on top to...
The Clean Air Group, LLC has designed gas cleaning equipment for rocket engine emissions for the Mercury and Apollo space mission programs as well as for Polaris and ICBM rocket fuel destruction. During the 1980’s, the Company was the sole source for the Strategic Defense Initiative (SDI) program to simulate outerspace using our Process Vacuum and Air Pollution control technology.
Hotel & Resort waste volumes are expected to increase over the next few years, due to an increase in tourism generally. High amounts of food waste and packaging waste are generated on a daily basis and need to be disposed of in a environmentally sound way. Our range of general waste incinerators are broad enough to cater for any sized hotel operation. If you run a large scale island resort or a small independent hotel, we have waste solutions that will fit your budget and waste capacity.
