Discover the Delta Breez Signature Series Exhaust Bath Fan, designed for efficient and quiet ventilation in your bathroom. This advanced fan features innovative brushless DC motor technology, ensuring hushed operation at less than 0.3 Sones (80 CFM) and 0.5 Sones (110 CFM). The fan offers full-speed adjustability, allowing you to switch between 80 and 110 CFM to meet your specific needs, ensuring optimal air quality and comfort. Illuminate your bathroom with 1,000 Lumens and a 90 CRI for precise color accuracy. Choose between 3000K, 4000K, and 5000K color temperatures to customize your ambiance. The sleek grille features edge-lit LED lighting for modern style. This fan boasts a 30,000-hour LED lifespan, significantly longer than typical CFL bulbs. The included 13-watt dimmable LED light provides efficient illumination (equivalent to a 60-watt incandescent), but a dimmer switch is not included. Energy efficiency is at the heart of the Delta Breez Signature, boasting an impressive 11.7 CFM per watt, significantly reducing energy consumption and lowering your utility bills. The fan includes a convenient 6-inch to 4-inch duct reducer, making installation a breeze in a variety of setups and ensuring compatibility with your existing ductwork. For continuous low-speed mode, the fan runs continuously at a user-preset lower level (0, 30, 50, 60, or 80 CFM), with delay time preset positions (0.5, 5, 15, 30, 45, or 60 minutes). Green and amber LED indicator lights show continuous low-speed and full-speed modes, providing clear and simple operation. Experience the difference with a fan that combines quiet operation, energy efficiency, and versatile performance, enhancing your bathroom experience with innovative technology and exceptional design.
