The Power of Performance, with Exclusive Smart Sensing Technology
WhisperSense DC is a precision spot ventilation fan that features built-in dual sensor technology (motion & moisture) that provides built-in redundancy for the ultimate in automatic moisture and odor control. WhisperSense DC improves IAQ by effectively removing moist, polluted air from any room. A powerful, yet efficient ECM Motor with SmartFlow™ technology ensures optimum CFM output, regardless of a long or difficult duct run.
ECM Motor with SmartFlow™ Technology
WhisperSense® DC™ is designed to perform as rated. When the fan senses static pressure, its speed is automatically increased to ensure optimal CFM output.
Pick-A-Flow® Speed Technology
Built-in Pick-A-Flow® speed selector provides the unique ability to select your required airflow (50-80-110 CFM) with the simple flip of a switch.
Dual Sensor Technology – Motion and Moisture
Three ways the fan can function
- Motion on/Motion off
- Motion on/Humidity off
- Humidity on/Humidity off
Variable humidity controls from 30-80% Relative Humidity (RH)
Adjustable delay timer from 30 seconds to 60 minutes
Long Life Means Reduced Costs
When you have a household or business to run, you don't want to have to replace little things like a vent fan. Panasonic fans use less energy to move larger volumes of air than other brands. Consequently, Panasonic fans run cooler so they last longer. They are also much less likely to overheat and result in motor failure. The motor is also equipped with a thermal-cutoff fuse.
The Flex-Z Fast™ Installation Bracket with articulating joints is ideal for positioning the fan exactly where you want it, in old or new construction. WhisperCeiling DC incorporates an integrated dual 4 in. or 6 in. duct adapter to give you flexibility in duct layout and design.
ENERGY STAR® Certified for Energy Savings
Panasonic ventilation fans are ENERGY STAR® certified, where guidelines exist. ENERGY STAR® vent fans meet strict parameters set by the US Environmental Protection Agency (EPA). They provide better efficiency and comfort with less noise, and feature high performance motors and improved blade design, providing better performance and longer life.
WhisperSense DC was awarded 2018 Most Efficient. This mark recognizes WhisperSense DC as delivering cutting edge energy efficiency along with the latest in technological innovation. It is an award that represents the best of those products that qualify for ENERGY STAR®.
