TWO EXTERNAL VENTS IN ONE! Imagine... Only one hole to cut in the exterior wall to perform an outdoor connection for an HRV or ERV. Introducing the simplest way to perform the outdoor connection for units that have a flow rate of less than 110 CFM (0.4 in. w.g.) : the Dual Exterior Hood Kit.
Pressure drops (air exhaust)
• Only one 6” diameter hole in the exterior wall • Aesthetic white polypropylene dual outdoor port
0.25
• Transition fits both 5” or 6” diameter insulated flexible ducts
• Light materials, handy design • Outdoor connection performed in half of the time • Complies with ASHRAE 62.2-2016 The revolutionary design of the Dual Exterior Hood Kit simplifies the installation because there is only one hole to cut in the exterior wall. In fact, every installer knows that locating efficiently one outdoor port is easier (and faster) than locating two. And moreover, there is almost no cross-contamination between the exhaust and intake airflows!
