REPLACED BY MODEL # FV-08VK3 Panasonic WhisperGreen Bathroom Fan with DC Motor - FV-08VK1 80 CFM: 5.9 Watts 7.2 CFM/Watt: 0.3 sones 6 Year Warranty on DC Motor Duct Diameter (inches): 4" Mounting Opening (inches sq.): 10 7/8" Grille Size (inches sq.): 13" Constant CFM Performance This WhisperGreenT model features built-in intelligence called SmartFlowT Optimum CFM Technology. This unique "electronic-brain" lets the fan do what was once thought to be impossible: perform at a constant CFM regardless of elbows and other factors that might hinder performance. Basically, when a WhisperGreenT fan faces static pressure, its speed is automatically increased to ensure that the desired CFM is actually achieved. This allows the fan to perform as rated and makes for easier installation because the installer no longer has to worry as much about compromising the fan's performance. DC Brushless Motor Panasonic's DC brushless motor provides unparalleled energy efficiency with its magnetic rotor and print circuit board. The magnetic rotor prevents energy loss while the print circuit board incorporates a unique IC chip which monitors and directs the RPM of the fan blade. The combination of these two unique features allows the DC motor to have higher energy efficiency than an AC motor. Quiet Motor Means Quiet Operation Panasonic is the first ventilation fan manufacturer to incorporate a DC motor in residential mechanical ventilation fans. The WhisperGreenT series incorporates a totally enclosed DC motor designed for extremely quiet, energy-efficient operation. The permanently lubricated motor is also engineered for trouble-free, continuous run for several years. 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 of our fans are ENERGY STAR-qualified and labeled accordingly.

Comments about Panasonic Panasonic WhisperGreen Bathroom Fan with DC Motor - FV-08VK1:

This is a great fan. With a depth of 8" we only had one house location this fan would fit. Its is a great fan however and I would have put it in all three baths if I had a choice. Very quiet. You only hear air movement itself. It is a little difficult to use this fan as a retrofit for an older fan just do to how they mount but it can be done (more easily if the previous fan was direct joist mounted).

Comments about Panasonic Panasonic WhisperGreen Bathroom Fan with DC Motor - FV-08VK1:

I was not sure what .3 sones sounded like when i ordered the fan but comparing it to displays in hd and lowes, it's didn't really sound much quieter than 1.5 - 2.0 sones. It's not an unpleasant sound that it make with is nice.

Also it uses very little power, so little that the first timer i installed did not work correctly since there was not enough current draw.

I think the damper could have been a little better too, doesn't look like it would seal much in a back draft.

Comments about Panasonic Panasonic WhisperGreen Bathroom Fan with DC Motor - FV-08VK1:

Very quiet. Make sure you don't restrict the exhaust though or it will make a whining noise. Does not include very good instructions for installations in existing homes, tailored towards new construction. Once installed it works very well and is extremely quiet.

I used 2 of these as bathroom extractor fans. They are quiet. I only wish I had used solid vent pipe rather than the accordion style Mylar plastic stuff!

Comments about Panasonic Panasonic WhisperGreen Bathroom Fan with DC Motor - FV-08VK1:

- There is no way this fan is 0.3 sones.
- I connected it using a 4" insulated duct
- Can here some whine from the AC to DC converter
- Way louder than 0.3 sones. More like 2.0 sones but still much quieter than the Broan fan it replaced which was 4.5 sones.
