WhisperGreen Select™ Model: FV-0511VKS2, Ventilation Fan with Pre-Installed Multi-Speed

WhisperGreen® Select ventilation fans are a ground-breaking IAQ solution that has revolutionized the ventilation fan industry with a set of features that enables customization and easier installation. To the builder and professional installer, Panasonic continues to be the innovation leader with high-performance ventilation solutions that are built to last. WhisperGreen® Select ventilations fans' unique design and superior energy efficiency are achieved through engineering expertise, provided by a company that sets the standard for quality and value.  

WhisperGreen® Select ventilation fans meet stringent green building codes and standards, including ASHRAE 62.2, LEED, ENERGY STAR® for Homes 3.0, IAP, JA8 Title 24, CA Title 24 and WA Ventilation Code.  


*Ceiling Radiation Damper: WhisperGreen® Select ventilation fans are UL listed for use with the Panasonic FlexDamper® (Model #: PC- RD06C6, sold separately).

Installed Performance guarantees up to .375” w.g. static pressure and certified quiet operation at 0.25" w.g. static pressure

Although ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at 0.1” and 0.25" w.g., WhisperGreen® Select fans not only provide the powerful CFM output at 0.375" w.g. that is more representative of most installations.  Sones have also been certified at 0.25" w.g. to provide a more realistic installed value. So they are quiet under pressure and after installation. 

Pick-A-Flow® Airflow Technology – You Choose The CFM

Built-in Pick-A-Flow® Airflow 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.

Plug 'N Play® Modules - Further Customize Your Fan

WhisperGreen® Select ventilation fan's customization features kick in with a set of patented Plug 'N Play® modules that give you the flexibility to design the perfect fan in advance, or on the fly, for a variety of ventilation applications. The first snap-in slot is dedicated to the pre-installed Multi-Speed (0, 30 to 110 CFM) module with high/low delay timer. The two remaining slots can accommodate the SmartAction® Motion Sensor and/or Condensation Sensor. Refer to the Accessories Tab for more information on our remarkable Plug ‘N Play® modules. 

ECM Motor- Best Performing, Most Energy Efficient Motor Available

WhisperGreen® Select fan features the same revolutionary ECM motor that comes with our WhisperGreen® line of products. With built-in SmartFlow™ technology, the fans are designed to perform as rated, providing precision ventilation. When the fan senses static pressure, its speed is automatically increased to ensure optimal CFM output. 

WhisperGreen® Select fans are designed to perform as rated. When the fan senses static pressure, its speed is automatically increased to ensure optimal CFM output. These features provide peace-of-mind, as the installer does not have to worry about compromising the fan’s performance, even with a complicated duct run. 

Fast, Flexible and Easy Installation

The Flex-Z Fast® Installation Bracket, with single-hinge articulating joints to easily position bracket in between the joist and/or through ceiling hole, lets you install the fan exactly where you want it, in old or new construction. WhisperGreen® Select fans incorporate an integrated dual 4 in. or 6 in. duct adapter offering 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 in. duct. Also fits in 2" x 8" construction. 

 Panasonic fans are UL listed for tub/shower enclosures; just install them on a GFCI-protected circuit. With these great features, your installation options open up. 

ENERGY STAR®- Certified for Energy Savings

Panasonic ventilation fans are ENERGY STAR® certified, where guidelines exist. They've been engineered to comply with the ENERGY STAR® 4.0 requirement for increased efficiency (CFM/Watt), ensuring low cost, energy efficient operation. 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.
