FabricAir Systems discharge air through a combination of porous fabrics, engineered orifices, and linear vents. FabricAir Systems are used to distribute and disperse air in open or below finished ceiling architecture, and are a more efficient, cost effective and aesthetically attractive alternative to metal duct work. FabricAir is used to distribute and diffuse heated, cooled, refrigerated, and make-up air to meet a large range of HVAC and refrigeration requirements in virtually any market segment. Different than conventional metal, fabric products are engineered and manufactured specifically for each project. FabricAir designs can be simple, straight systems or very intricate layouts which incorporate fittings such as radius elbows, Ts, and transitions. Sections are zippered together to form extended lengths with diameters from 6 to 80 inches. In open ceiling architecture, traditional metal duct systems discharge air through side-mounted metal diffusers usually spaced 10 to 15 feet apart. The air is directed to specific zones resulting in less efficient mixing of air in the occupied space and often causing drafting and hot or cold spots. With a FabricAir System, the air is discharged more uniformly along the entire length of the duct, providing consistent and uniform air dispersion in the occupied space. Better air dispersion means better air mixing. Temperatures are achieved a lot quicker, therefore providing an energy saving.
