Key Features & Innovations


cULus Certified

Smart Flow Technology

The revolutionary DC motor with intelligent self-adjusting SmartFlow technology senses the amount of resistance in the duct run and automatically adjusts the fan speed to deliver the optimal CFM output, even in the case of a complicated duct run. The Panasonic DC motor with SmartFlow technology moves more air using less energy, so the fan is more energy efficient and lasts longer. Designed to run continuously, WhisperGreen Select can deliver whole-house continuous ventilation.

Panasonic-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. Being able to choose the proper CFM level gives you the flexibility and assurance that one fan will satisfy a range of ventilation design requirements and perform as promised, even with a complicated duct run.

Energy star

Energy Star certified vent fans meet strict parameters set by the US Environmental Protection Agency. Panasonic ventilation fans are Energy Star certified where guidelines exist, and provide greater efficiency and comfort with less noise. High performing motors and improved blade design deliver superior performance and long life you expect from a premium Panasonic ventilation fan.


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. WhisperGreen Select incorporates an integrated dual 4" or 6" duct adapter to give you flexibility in duct layout and design. For short runs, you can go with a smaller duct size, but long runs are ok too - just move up to the 6" duct. Also fits in 2 x 8 construction. Panasonic fans are UL listed for tub/shower enclosure (just install them on a GFCI-protected circuit). With these great features, your installation options open up.
