Metal Tandem Hood
ONE OUTDOOR PORT FOR DOUBLE USAGE
More than ever, today’s builders and contractors are aiming to
optimize material, manpower and time. One way to achieve this goal
when installing a ventilation system is to install our new metal tandem
hood. This new device simpli es the installation not only because
only one hole is required on the exterior wall. In fact, every installer
knows that locating e ciently one outdoor port is easier (and faster)
than locating two. Moreover, there is hardly any intercontamination!
• Galvanized satin steel cover grille (ready to be painted by the HVAC
contractor to match building’s color).
• One 7” x 18” hole in the exterior wall.
• Tandem box eliminates the need of a Tandem transition.
• Intake and exhaust ducts connection can be performed either on
left or right port, for more convenience.
• Outdoor connection performed in half time.
• Suitable for ventilation unit producing an air ow lower than
120 CFM (for higher air ow capacity, please con rm that the overall
pressure losses of the ventilation system is suitable for the unit used).
