The five new models are low-profile ENERGY STAR fans, featuring a housing depth of just 3 3/8 inches to mount easily in a slim 2- by 4-inch- (actually 3 1/2-inch-) deep joist cavity or stud wall. The unique L-shaped bracket also simplifies installation, while providing strong support. UL approved radiation damper is available for fan only models in ceiling installation. The WhisperValue and WhisperValue Lite are also UL approved for wall mount, making them the ideal choice for multifamily applications. Wall installation reduces costs for builders by eliminating the need to incorporate a radiation damper when penetrating fire-rated ceilings.
Panasonic will continue to offer a Universal-Can (U-Can) Contractor Pack for the new generation of WhisperValue and WhisperValue-Lite fans. The U-Can Contractor Pack allows contractors to install the housing of the fan right after the framing of the structure, and then the motor and grille can be installed at a later time when construction is complete. This provides flexibility during the construction process and allows contractors to store the components separately to minimize the risk of parts being lost or damaged onsite.
New models are able to achieve installed performance, having a high airflow circulation of 50, 80 or 100 CFM (cubic feet per minute) at extremely low noise levels at both 0.1- and 0.25-inch water gauge (w.g.) static pressure. The FV-08VSL3 and FV-10VSL3 80 and 100 CFM lighted models now feature a contemporary grille design with two 13-watt, self-ballasted GU24 base CFL lamps and a 4-watt nightlight.
All WhisperValue and WhisperValue Lite models can be used to comply with ASHRAE 62.2, the ventilation platform adopted by LEED for Homes, ENERGY STAR for Homes 3.0, California Title 24, and Washington Ventilation Code.
