Engineered for continuous operation, Energy Star–rated Ultra Silent QTXE ventilation fans are quiet at 0.3 to 1.4 sones and are designed for use with a 6-inch duct. Louvers hide the fan housing at almost any angle, helping the grille to blend in with the ceiling, the company says, and a 16- to 24-inch-span hanger bar system allows for easy installation in all types of construction, the maker adds. It includes a five- to 60-minute shut-off timer. 800.558.1711.
