MONTREAL—The Circul-Aire subsidiary of Dectron Internationale, Roswell, Ga., has introduced Circulaire Cleanaire, efficient and sustainable gas-phase air filtration media for removing chemical odors and airborne gaseous contaminants in industrial complexes, laboratories, office buildings, healthcare facilities, schools, hotels, museums, and other commercial buildings where indoor air quality (IAQ) is critical.
The Circulaire Cleanaire proprietary process produces a randomly-shaped, coarse-surfaced, granular media resulting in multi-faceted macro surface adsorption capacity that’s superior to the industry’s conventional smooth-surfaced and symmetrically-shaped media pellets. Each granule’s rough surface increases contact and adsorption with air stream gaseous contaminants, thus creating a more efficient and adsorbent process. Consequently, Circulaire Cleanaire media lasts longer, which significantly reduces a building’s annual HVAC maintenance and media replacement costs, according to recent laboratory tests conducted by Christopher Flaherty, director of Laboratory Services, and Dr. Chang-Seo Lee, associated with the Department of Building, Civil & Environmental Engineering at Concordia University, Montreal.
The Circulaire Cleanaire coconut-based composition makes it a significantly greener gas-phase media to use with less environmental impact during disposal than the coal-based carbon media used by the competing gas-phase filtration manufacturers. Circulaire Cleanaire is a dual mix of MM-1000NS and MM-9000CLT media that is designed to remove all gaseous contaminant by-products from vehicle emissions such as nitrogen dioxide, sulphur dioxide and nitric oxide, as well as ozone, volatile organic compounds (VOC), plus lower molecular weight aldehydes and hydrocarbons.
