## Description

Product description Comparison Table WhisperGreen Select WhisperWarm WhisperFit WhisperValue WhisperCeiling Ecovent

Review: Easy Installation, Great Performance, and Very Quiet - I have done seven ventilation fan replacements between my previous house and current house using the Panasonic fans. Builder-grade ventilation fans just did not cut it - they were loud and useless. Of the seven Panasonic fans used five are previous model FV-08-11VF5 (other than using AC motor and having just 80/110 CFM selections, it is identical to the FV-0511VF1 under review). Two are FV-0511VF1. They are all excellent ventilation fans, probably the best retrofit option for the home owners due to their easy and innovative installation method. Especially if the access to the space above ceiling is limited. FV-0511VF1 uses DC motor and it takes about a minute to reach its full speed, unlike the previous AC motor model which reaches full speed in less than 10 seconds. Once reaches the full speed I can feel the air flowing and it is pretty quiet (especially compared to the builder-grade fans I replaced). One thing to keep in mind, even though this fan comes with a 4"-to-3" duct adapter, I recommend using 4" duct whenever possible to get the best performance and the lowest noise level out of the fan. Of the seven replacements I have done, I was able to replace six original 3" ducts with 4" ducts through attic space. I was not able to replace the downstairs bathroom one as its duct goes through floor and ceiling space that I have no access to. And this one definitely has less performance and higher noise level than the other six.
Review: Well made, Easy to install, Quiet operation. - The best made exhaust fan that I have seen. The fan uses a very quiet DC motor housed in a nicely designed injection molded fan housing. The assembly is shock mounted to the frame to decouple vibration from the ceiling. The fan speed is controlled by a built in controller that allows the maximum operating speed to suit the size of the room. It also uses the speed control to increase the speed slowly to the maximum speed. It goes from completely silent to through barely audible to its impressively low noise maximum speed. It is not silent but the term whisper quiet is not too far from fact. It is not inexpensive but given the high quality it does represent good value for money. It should last a long time without any of the vibration and rattling of cheap metal alternatives. Highly recommended.

## Questions & Answers

**Q: What are the dimensions of this fan?**
A: Outer grate 13" x 13"
Recessed guts: 10.25" x 10.25"/ 5.625" high

**Q: What is it about this kit that makes it preferable for retrofitting versus new builds?**
A: This is good for both new and remodel construction.
(Existing replacement) The fan is bigger than most fans that are being replaced so there isn’t need for drywall patches/paint. The flexible bracket makes it extremely easy. If you have basic tools, a little experience with remodel work and take your time you won’t need to go into attic at all, or if you use the slim low profile version it can be done in between upstairs and downstairs situations. I’ve installed over 200 Panasonic exhaust fans as a professional electrician over the years. They are one of the only exhaust fan brands that I can honestly recommend. Hands down the quietest as well. There is a reason they cost more than the builder grade $15 Broan fans that come in most houses.

**Q: The product description says "dc".  does that mean it will or won't run off of standard 120v ac current?**
A: These fans run on normal US 120v … The “ DC” motor is powered internally once you supply 120v AC power and is better quality & makes it quieter.
Hope this helps …

**Q: does this have a 30 day return window? Not sure it will be right and installer not doing for 10 days**
A: Mine worked, didn't worry about 90days

### ⭐⭐⭐⭐⭐ Working well in a sloped catherdral ceiling
*by M***E on September 21, 2024*

This Panasonic bath fan has all the great features Panasonic fans are known for: ease of installation, clean look, quiet operation, reliability and effective ventilation. I installed this fan in a bathroom in a sloped ceiling which I had access to via the attic. I do not think it is rated by the manufacturer for an angled installation. I was concerned the bearings might not be happy with this orientation, and might give out early. But I needed a fan and I've had great success with a previous Panasonic bathroom ventilation fan. I made sure the fan's baffle was oriented properly (I had to point the outlet port facing up towards the peak of the ceiling to ensure it would operate properly). I initially set this fan at its highest CFM rating (110 CFM or so, I can't remember exactly). But it started to make a slight squeal after running for several minutes. I backed off the fan to 80 CFM and no more squeal. It has been in place more than 6 months with daily usage and has not squealed again. The ventilation is excellent. There is no moisture on the mirror after a long shower. For the record, this bathroom is about 9' x 10', and the sloped ceiling adds much more volume to the room. The ventilation duct is 4" galvanized steel (smooth) with a short 4" aluminum flex section to help ease the initial connection to the fan. This duct runs about 8 feet in total with two elbows at about 15 degrees, plus another 90 degree elbow, then vents through a Broan 4" vent hood in the roof. The ventilation is excellent even with all those elbows, and length, and the lower 80 CFM speed setting. I skipped the moisture sensing option, preferring the fan to run only when someone turns on the switch. I installed a Leviton DT130 countdown timer switch (5-10-15-30 minute) and its been great. You can have this switch stay on indefinitely if you want. It's a Decora style switch and easy to install.
