OvalSox™ fabric duct is designed for low-clearance HVAC ventilation in industrial and commercial building applications. The fabric duct ranges from 11-22 inches high and 47-93 inches wide. in industrial and commercial building applications. It is ideal for datacenters with high-rising security cages or low-hung ceilings in offices and other commercial designs, the company said. The fabric duct 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-inch-diameter ropes are sewn into the fabric interior at 9-14 inch increments, which also present an aesthetic pleated effect, and, 3⁄8-inch-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 easily installed rows of cable or H-track suspension systems that help keep an inflated shape with minimal sag, said the company. OvalSox applications can also be combined with traditional round fabric via a transition fitting. The fabric duct is available in a variety of colors based on selected fabric as well as custom colors.
