Bath Fan Duct
The Lambro 3-inch x 25-foot UL 181 Class 1 air connector ideally serves bath fan exhaust and any other general venting applications that require the expulsion of moist air and humidity from the home.
The manufacturer process constructs this bath fan duct from multiple layers of aluminum/polyester material bound together with a fire retardant adhesive that can withstand a maximum operating temperature of 257°F. A galvanized wire helix supports the duct, preventing it from collapsing.
Per the UL 181 Class 1 guidelines, you should refrain from installing this duct in lengths exceeding 14 feet. However, you’ll be able to cut it to the required size.
Make sure to check local building codes before installation.
