WhisperLine™ 340 CFM In-Line Fan


WhisperLine™ 340 CFM In-Line Fan


Ventilate Multiple Areas with Just One Fan

Panasonic WhisperLine™ fans are designed for multiple-task ventilation. This means that you can ventilate multiple areas or multiple rooms with just one fan. For example, you can place inlets over the shower, tub, toilet and/or vanity in a single bathroom and still use just one fan. In recent years, homes have become more airtight and energy efficient. While this lowers the cost to heat and air-condition a home, it also retains pollutants that can be hazardous to its occupants. One way to improve the air quality of the home is through whole-house ventilation with a Panasonic WhisperLine™ fan, which removes "stale" air and provides fresh air on a slow, continuous basis.

So Quiet You Might Not Know it's On

WhisperWarm™ fans feature a totally enclosed condenser motor and a large, double suction blower wheel to quietly move air. A small wheel turning very fast will create more noise than a large wheel turning more slowly for a given airflow. Our fan uses a wide blower wheel that moves a large amount of air at reduced RPMs. The blower wheel is also designed to draw air in from both sides, which helps keep the noise down, as there is more area for the air to enter the wheel. In fact, it is quiet enough that you might not even know it's on.

Adjustable Airflow for Multi-Inlet Balance

Low profile, family-designed grilles feature an adjustable airflow so you can balance the airflow from multiple inlets. Inlets closest to the fan will "pull" more air than ones further from the fan. By adjusting the inlets, you can balance the airflow from each inlet to create even air circulation.

Easy Installation

This in-line fan can be installed in five different positions and joist, truss and suspension brackets are included to help make your installation as easy as possible.

Continuous, Trouble-free Operation for Many Years

This fan is designed to give you continuous, trouble-free operation for many years thanks in part to its high-quality components and permanently lubricated motors which wear at a slower pace. Also, since heat is always detrimental to motor life (the cooler the environment, the longer the motor will last), we designed the electrical configuration of this model's condenser motor to allow it to operate at lower temperatures, increasing the life of the motor and bearings. And, the fan housing is made of heavy-gauge zinc galvanized steel and painted to protect it from rust.

Energy Star® Qualified for Energy Savings

Energy Star qualified products feature super-quiet operation and high CFM-to-Watt efficiency. The Energy Star program was created to help consumers identify products that can save them money and protect the environment by saving energy. As an Energy Star partner, all our fans are Energy Star qualified and labeled accordingly.
