Panasonic WhisperValue DC 50, 80 or 100 CFM, Model FV-0510VS1

Panasonic WhisperValue^® DC™ FV-0510VS1 Fan is the perfect multifamily solution, also ideal for single family and manufactured homes. As the lowest-profile ENERGY STAR^® certified fan available, it actually fits in a 2x4 stud bay. The low profile, 3-3/8" housing depth and unique L-shaped bracket allow this fan to be installed virtually anywhere - in ceilings or walls.

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.

The Built-in Pick-A-Flow™ speed selector provides the unique ability to select your required airflow (50, 80 or 100 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.
