Panasonic is using this week’s International Builders’ Show to debut its new lineup of WhisperGreen ventilation fans.

Rated at 110 cubic feet per minute, the models, FV-11VK3 and FV-11VKL3, will be available in April.

“At Panasonic, we pay close attention to industry demand when developing new products,” said Anita So, marketing manager with Panasonic’s Home & Environment Co. division. “With 110-cfm becoming more of an industry standard, we have expanded our WhisperGreen since builders and contractors have come to love all of the innovative features of the product line. These new 110-cfm models will continue to improve indoor air quality in homes and light commercial applications by removing pollutants, allergens and stale air, all while operating with superior energy efficiency.”

Fan features include SmartFlow CFM technology that detects and compensates for additional static pressure by increasing airflow, and an efficient DC motor, allowing the fans to be up to 592 percent  more energy efficient than Energy Star standards, Panasonic said.

The new models also include dual adaptors for 4- or 6-inch ducts, making them ideal for renovation or new construction, officials added.

The 2012 International Builders’ Show runs today through Saturday at the Orange County Convention Center in Orlando, Fla.
