Smart Bath Fans Battle Home Moisture Problems

Smart Bath Fans Battle Home Moisture Problems

Those long showers people enjoy so much could be hurting the very house they live in. How? The humidity and moisture that is built up from the shower is in a concentrated space—the bathroom—creating the perfect breeding ground for mold and mildew, which can damage building materials, including drywall and wood framing.

Fortunately, there is a solution—the bathroom ventilation fan. Designed for residential construction and newly built homes, the Panasonic WhisperValue DC is an ideal multi-family ventilation solution that is revolutionizing the ventilation fan industry with a new set of features that enable easy code compliance and longer service life. The advanced Condensation Sensor technology makes life easier by automatically detecting dew point and turning the fan on to control humidity. Furthermore, the Multi-Speed with Time Delay, allows the selection of proper CFM settings to satisfy ASHRAE 62.2 continuous ventilation requirements.

Panasonic’s SmartFlow technology moves more air using less energy, so the WhisperValue DCTM is more energy efficient and lasts longer.  The advanced ECM motor with intelligent self-adjusting SmartFlow technology senses the amount of resistance in the duct run and automatically adjusts the fan speed to deliver optimal CFM output, even in the case of a complicated duct run.

The Built-in Pick-A-Flow speed selector provides the capability to customize the ventilation fan for a variety of applications and to meet required airflow (50-80-100 CFM) with the simple flip of a switch. The ability to choose the most fitting CFM level gives builders and contractors the flexibility and assurance that one fan will satisfy a range of ventilation design requirements that meet code and perform as promised.

WhisperValue DC offers optional built-in features that allow the installer to further customize the

  • Multi-Speed with Time Delay, which allows the selection of proper CFM settings to satisfy ASHRAE 62.2 continuous ventilation requirements. The fan runs continuously at a preset lower level (0-30-70, in 10 CFM increments) then elevates to a maximum level of operation (80 or 100 CFM) when the wall switch is turned on. A High/Low delay timer returns the fan to the preset CFM level after 20 minutes.
  • Condensation sensor, which helps control bathroom condensation to prevent mold and mildew. The advanced sensor technology detects relative humidity and temperature to anticipate dew point, automatically turning the fan on to control humidity. Built in Relative Humidity (RH) sensitivity adjustment enables fine tuning for moist conditions and for satisfying CALGreen requirements. The fan will run for 20 minutes before turning off.
  • LED Lighting, features a contemporary flush mount grille that incorporates one 10W dimmable LED chip panel with <1W LED night light for warm, energy efficient illumination. Panel specifications include: 3000 Kelvin Warm White/90CRI/700 lumens/70 LPW/ENERGY STAR 2.0 certified/50,000 hours rated average life.

“WhisperValue DC is an enhanced version of our successful low profile, multi-family solution that now incorporates our ultra-energy efficient, ECM motor with SmartFlow® technology and customizable airflow for easy code compliance," said Patricia Monks, National Marketing Manager, Panasonic Eco Solutions North America. "WhisperValue DC can be used as your whole house ventilation solution and includes an Intelligent Condensation Sensor, which automatically controls moisture in order to optimize performance and reduce risk of exposure to harmful pollutants.”

The extremely thin profile opens up new options for where builders and contractors can install the WhisperValue DC, which is UL listed for ceiling or wall mount. The low profile, 3-3/8” housing depth and unique L-shaped bracket allow this fan to be installed in virtually any ceiling or wall. Wall installation reduces cost by eliminating the need to incorporate a radiation damper when penetrating fire rated ceilings. As the lowest profile ENERGY STAR® rated fan on the market, the WhisperValue DC actually fits in a 2x4 stud bay, right out of the box.

As with all fans in the lineup, WhisperValue DC can be used to comply with ASHRAE 62.2, LEED, IAP, California Title 24, CALGreen and WA Ventilation Code.
