|Installation (Typical Basement, Central Draw Point)|
Fresh filtered air is distributed through the whole house. Only one outside connection is needed when using the Tandem transition and the AirDuo port, simplifying the installation.
|The exclusive Tandem transition never mixes stale air (1) (coming from its unit (3)) and fresh air from outside (2) (going through its unit duct (4)). Both transition AirSnap ports can be fitted with 5 inch and 6 inch diameter insulated flexible ducts.|
Also shown is the AirDuo exhaust/intake air vent which mounts on the exterior of the house. AirDuo is paintable and UV-ray protected. The AirDuo typical cross contamination is < 3%.
