User questions & answers

Question:	does it work in a kitchen
Answer:	Yes
Question:	What is the housing dimensions
Answer:	Don't know I wouldn't
Question:	can i get a fire damper for this
Answer:	Yes, with your heater on and the fan blowing the warm air should spread out evenly.
Question:	Can this unit be mounted in a wall
Answer:	Not really, since it moves a lot of air. I'm not sure how quiet something that forceful can be. I needed it to move air out the windows so the 20' x 20' room could then be detoxed (cats) with an air purifier. I guess whether the noise is a factor, tho it's not as bad as many others, is a personal choice.

User questions & answers

Question:	how difficult is the install without a preexisting fan
Answer:	There are two metal mounting brackets on the fan that mount to the structure with screws. A 3" flexible duct runs from the fan to a wall or roof cap. Two adjustable 3" metal screw clamps are required to hold the 3" flex duct to the fan & cap. An electrical circuit is required to power the fan & it requires an on-off switch. This requires a moderate amount of skill.
Question:	Will this replace 688-k? The K seem difficult to match. Thanks
Answer:	Yes, it will. The model is 688. The "K" just indicates which version of the 688 your fan is.

From the Manufacturer

The Panasonic FV-40VQ3 WhisperCeiling 380 CFM fan features a totally enclosed condenser motor and a double-tapered, dolphin shaped bladed 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. Panasonic fans use a wide blower wheel that move a large amount of air at reduced RPMs, so they are quiet enough that you might not even know they're on. With a 3.0 sone level and rated 380 cubic feet per minute, this fan is designed to give you continuous, trouble-free operation for many years due to its high-quality components and permanently lubricated motors which wear at a slower pace. 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. This Energy Star qualified fan has a built-in damper to prevent back draft, which helps to prevent outside air from coming through the fan. The Panasonic FV-40VQ3 WhisperCeiling 380 CFM Ceiling Mounted Fan is covered by a manufacturer warranty for period of three years from the date of the original purchase and is sold one item per package.

• Quiet air flow: Designed for light commercial applications, this powerful yet quiet ventilation fan moves 390 CFM of air at 3.0 sones
• Long life, guaranteed: Panasonic ventilation fans use less energy to move larger volumes of air. Less energy leads to less overheating and motor failure, saving you on repair costs. Included 3-year limited warranty
• Easy to install: Designed for 6" ducts. The double hanger-bar system (expandable up to 24") is ideal for positioning the fan exactly where you want it
• Clean air: Panasonic ventilation fans will increase your air quality, eliminating humidity, mold, mildew, and other air pollutants from any room
• Code compliant: This product is ENERGY STAR 3.0 certified and complies with ASHRAE 62.2, LEED, California Title 24 and WA Ventilation Codes

User questions & answers

Question:	Has anybody installed this recently in a standard 16 inch on the center ceiling joist? It appears some older models were too wide to fit
Answer:	I prefer to set it manually
Question:	hi, why your fv-40vq4 picture which show on the top is different from the website site of the panasonic. Does your product is the latest product
Answer:	4".
Question:	can a dimmer be used for this fan to make the noise lower
Answer:	I put this in a total renovation where we took the walls and ceiling to studs so placement was easy. Our house was built in 1980 and 3” tubing was used. Now it is 4” and that is all I could find in the big box stores. I could not make the hole to outside bigger but found an adapter at amazon. The outlet on this is oval so I used flex tubing and secured it with a hose clamp and foil tape.
Question:	Does this fit in standard ceiling joist
Answer:	noise level rating. The lower the sone level, the quieter the fan
