Fabric duct: DuctSox
DuctSox has introduced the OvalSox™, fabric duct designed for low clearance HVAC ventilation in industrial and commercial building applications. OvalSox, which ranges from 11 to 22 in high and 47 to 93 in wide, saves 13 to 27 in of head room versus round HVAC fabric and metal duct alternatives, according to the company. Officials also claim there is no air volume or air dispersion lost with OvalSox versus conventional duct that hangs too low and obstructs industrial overhead conveyors or high rising equipment. OvalSox is also ideal for datacenters with high rising security cages or low hung ceilings in offices and other commercial designs.
OvalSox retains an inflated shape even during idle air handling periods with patent-pending polyester ropes and supportive fiberglass rods for structural integrity. Six 3/16-in-diameter ropes are sewn into the fabric interior at nine to 14-in increments. Additionally, 3/8-in-diameter corrosion-proof white fiberglass rods are attached via sewn-in clips atop the fabric surface to accentuate an inflated appearance. OvalSox is ceiling hung with two rows of cable or H-track suspension systems that also help keep an inflated shape with minimal sag.
OvalSox applications can also be combined with traditional round fabric via a transition fitting. There are many DuctSox fabric options available, including Sedona Xm™, Tuftex™, Verona™, Duratex™, Microbe-X™ for food processing, and Stat-X™ for anti-static electricity environments such as datacenters. OvalSox is available in a variety of colors based on selected fabric, as well as custom colors.
