WhisperLine ventilation fans can vent multiple areas.
When it comes to zoning, contractors and manufacturers tout the benefits of heating and cooling multiple areas of a home. But what about using zoning for ventilation in a residence?

Two years ago, Panasonic introduced the WhisperLineâ„¢ to its line of Advanced Ventilation Fans. The new models are remote, mounted in-line ventilation fans that can be used for single or multiple inlets.

"The primary benefit of these fans is allowing to vent a number of rooms with just one motor [or] blower," said Larry Hershkowitz, marketing manager for Panasonic.

Hershkowitz explained that by using Y-adaptors in the ducting, the duct can be split off and ventilate multiple areas, either covering multiple rooms or even areas within a large bathroom.

"Each area can be controlled by an independent switch," he said. "The Y-adaptors, along with the inlet grilles, can be purchased as separate installation kits, depending on the need."

The fans can be used for spot and/or continuous ventilation, and they can be completely controlled by the occupant, said Hershkowitz. The fans are designed to enable the homeowner to ventilate multiple areas and rooms with a single fan.

Hershkowitz explained that multiple inlets with one fan are generally less expensive than running independent exhaust fans. There are five available positions for installation, and each only needs a joist or truss, attachment brackets, and suspension brackets.

Models range from 120 cfm to 440 cfm. Depending on the model, these in-line fans utilize between 36.2 watts and 132.0 watts.

According to the company, the products are Energy Star qualified.

"While the primary benefit of the in-line fan is the ventilation of multiple areas, there is also the benefit of having the fan outside the bathroom further reducing the noise level in the area being ventilated," said Hershkowitz.

He noted that the fans also help to remove such pollutants as smoke and dust, as well as the humidity and CO2 that accumulate in poorly ventilated areas.
