first_imgThis week I’ll take a look at four new products of interest to residential builders: a supply fan from Panasonic, a high-efficiency HRV from Quebec, triple-glazed windows manufactured in New Jersey, and a plastic drainage mat from Tyvek.For decades, Panasonic has been manufacturing residential exhaust fans that are dependable, quiet, and energy-efficient. That’s why so many exhaust-only ventilation systems include a Panasonic exhaust fan.Recently Panasonic came out with a new fan, the WhisperFresh Select, designed to meet the needs of builders who prefer supply-only ventilation to exhaust-only ventilation systems.The WhisperFresh Select is Energy Star certified. The supply fan has an adjustable airflow delivery rate, with nine settings (from a low of 50 cfm to a maximum of 150 cfm). It is equipped with an ECM motor, and will automatically ramp up the fan speed in response to a filter that gets clogged in order to maintain a consistent air flow delivery rate.The fan draws 8.2 watts at 50 cfm, and 27.3 watts at 150 cfm.The WhisperFresh Select fan includes a replaceable filter. For those who want balanced ventilation (albeit without heat recovery), the WhisperFresh Select can be set up to communicate with a WhisperGreen Select exhaust fan to provide coordinated supply and exhaust ventilation.[Photo credit: Panasonic]The WhisperFresh Select fan includes a humidity sensor. The fan can be set up to shut off automatically when the outdoor relative humidity rises to a user-adjustable setting (anywhere from 30% RH to 80% RH).The fan also includes a temperature sensor. The fan can be set up to shut off automatically when the outdoor temperature drops to a user-adjustable setting (anywhere from 4°F to 15°F). The fan also stops operating when the outdoor temperature rises above 95°F.The WhisperFresh Select fan is available online for about $538.
