ANAHEIM, Calif. - You might be wondering, "What could possibly be new in the area of grilles, registers, and diffusers?" If you attended the 2004 International Air-Conditioning, Heating, Refrigerating Exposition, you wouldn't need to ask, as numerous manufacturers spotlighted their new technologies and upgraded products.
Airtec Products Corp. (www.airtecproducts.com) featured its Model MV diffusers, which incorporate both a diffuser outlet assembly and a damper. According to the company, the Model MV's unique design and contractor-friendly engineering save money by reducing installation time and effort by up to 80 percent. According to the manufacturer, patented design features make installation a snap: Cut a 9-inch diameter hole in the ceiling, insert the Model MV, and tighten four screws. As the screws are tightened, clips on the Model MV rotate into position, securing the unit in place. The stepped collar design accommodates 6-, 7-, or 8-inch round ducts.
