A new media-based adsorber for the control of airborne gaseous contaminants, CitySorb CH, is said to be ideal for HVAC uses in geographic areas where ozone may be a concern, or where the use of outside air for indoor contaminant dilution may be a problem because of elevated levels of other gaseous pollutants. The adsorber is available with a variety of media blends to suit different requirements, ranging from standard odor and removal of volatile organic compounds in HVAC systems to the control of corrosive gases, ammonia/amines, or oxidizable gases in specialized industrial settings. It is designed for installation in side-access filter housings or built-up banks using an integral one-inch nominal header. It offers low resistance to airflow, officials say.
