Built for Longevity
The Panasonic WhisperFit® DC Fan is designed with a focus on long-term durability and reliable performance for both retrofit and new construction projects. Its advanced ECM/DC motor operates at a lower temperature than conventional AC motors, reducing stress and extending its lifespan while providing superior speed control and energy efficiency. The low-profile, reinforced housing is only 5 5⁄8 inches deep, making it ideal for 2×6 or larger joist spaces and minimizing heat buildup. A solid plastic duct collar with back-draft damper and slide-and-snap junction box ensures a secure, air-tight fit that reduces air leakage and protects wiring from moisture-related wear.
Its compliance with ASHRAE 62.2, LEED, Energy Star, and California Title 24 standards reflects Panasonic’s commitment to quality, efficiency, and durability, making WhisperFit® DC Fans a dependable choice for lasting indoor air quality.
