Atmosphere

Atmosphere was incorporated in 1998, starting from a 2,000 square foot warehouse in Montreal before outgrowing several facilities and settling in 2008 into a 46,000 square foot green building headquarters and warehouse in Terrebonne, Quebec, a facility notable for one of the largest vegetative green roofs in Canada. The company designs and manufactures ventilation products that are exported from Canada to the United States, Brazil, and Australia.

Product Lines

SupplyHouse carries Atmosphere's Vortex in-line ventilation fans, including the VTX400 and VTX600 series, which use an aerodynamically shaped housing paired with a motor built for continuous duty in duct runs. The lineup also includes galvanized steel backdraft dampers in multiple round duct sizes, used to prevent reverse airflow in exhaust and ventilation runs.

Why Contractors Specify Atmosphere

Installers specify Atmosphere's Vortex fans for jobs where duct static pressure or run length would push a standard fan below its rated airflow, since the aerodynamic housing and motor design are built to hold performance under those conditions. The VTX series carries a 10 year warranty, giving installers a longer coverage window to point to when discussing product durability with homeowners or property managers. Because the fans and dampers are manufactured in Canada under one company's design standards, installers pairing a Vortex fan with an Atmosphere backdraft damper can expect consistent duct sizing and fit between the two products.

How to Choose Atmosphere Products

Sizing an Atmosphere Vortex fan starts with the duct diameter and the required airflow in CFM for the space being ventilated, since models like the VTX400 and VTX600 are built around specific duct sizes and fan curves. Long duct runs or installations with several elbows should be checked against the fan's static pressure rating rather than its free air CFM rating, since airflow drops as resistance increases. Any exhaust run venting to the exterior benefits from a backdraft damper sized to match the duct diameter, which keeps outside air and pests from entering the duct when the fan is off. Matching the damper and fan diameter to the existing duct, rather than resizing the duct to fit a preferred fan, keeps installation straightforward.
