The WhisperValue® DC exhaust fan is the ultimate low-profile, spot ventilation solution ideal for residential construction, including single-family homes, multi-family buildings, and manufactured homes. Featuring a revolutionary ECM motor, SmartFlow™ technology, and Multi-Speed Control in an ultra-slim design, it is the lowest-profile ENERGY STAR®-rated fan, perfect for tight spaces and continuous ventilation requirements.
The fan stands out with two key features: Multi-Speed Control for ASHRAE 62.2 Compliance, allowing continuous operation at a lower preset level (0, 30-70 CFM) and boosting to 80 or 100 CFM when activated, and the Pick-A-Flow® Airflow Selector, which lets you customize the airflow to 80, or 100 CFM. Together, these features make it easy to meet diverse ventilation needs, ensure code compliance, and minimize callbacks.
- Customizable Airflow with Pick-A-Flow® Selector: Select the CFM that suits your space—80, or 100 CFM—for precision airflow and optimal performance
- SmartFlow™ Technology: Automatically adjusts the fan’s speed to maintain peak performance, saving energy and ensuring the best CFM output
- Lowest Profile Design: With a housing depth of just 3-3/8", this is the slimmest ENERGY STAR® certified fan available, making it perfect for tight spaces and easy installation, even in 2" x 4" stud walls
- Cost-Effective Wall Installation: Wall-mounted installation eliminates the need for expensive radiation dampers in fire-rated ceilings, making it an ideal choice for multi-family projects
- Warranty: 6 years ECM Motor, 3 years all other parts
