The L-Vent is the cleanest vent in the industry for fabric duct in commercial building applications, claims the company. The new, standard L-Vent design includes one to three rows of orifices ranging from 1/4- to 1-inch openings that are factory engineered to produce airflows of 5 to 90 cfm per foot at 0.5 inch w.g. The updated configuration and the sealed, nonfraying edges help limit surface dusting. The L-Vent replaces S-Vents and Mesh Vents as the standard Comfort Flowâ„¢ model in most of the manufacturer's premium and commercial fabrics.
