Panasonic has expanded its line of WhisperGreen ventilation fans to include two models that feature a cutting-edge LED light and revolutionary DC motor that uses only 7.5 Watts, creating what the manufacturer claims are the most sustainable ventilation fans on the market. The ultra-quiet units offer an 80 CFM fan and operate at .25" w.g. static pressure; they fit in 2x8 construction, feature a rustproof paint treatment on the galvanized housing, and come with a 6-year warranty on the DC motor and a 3-year warranty on parts. The WhisperGreen LED FV-08VKME3 unit also features Panasonic's SmartAction motion sensor, which activates when it senses a person and returns to the lower speed when the occupant leaves the room. Both models are ENERGY STAR rated, HVI certified, and comply with ASHRAE Standard 62.2, CalGreeen, and California Title 24.
