About This Product
This WhisperFit DC Fan features a dimmable 10W LED light with 1W night light for warm, energy-efficient illumination. A built-in energy-efficient ECM (DC) motor with Pick-A-Flow airflow selector allows you to select required airflow (50, 80, or 110 CFM). Single-hinged Flex-Z Fast bracket, pre-installed alignment guides, and temporary clip allow for flexible, fast, and easy installation. This vent fan enables you to utilize existing duct, while its low profile housing design ensures a proper fit in any bathroom ceiling or other areas of a home with at least 5 5/8" depth. The slide and snap-in junction box and duct collar provide greater flexibility when wiring and attaching the duct, and this premium ceiling ventilation fan now includes preinstalled plastic alignment guides and temporary retaining clip. These clips molded into the casting will allow the fan to stay in place while the installer fastens the fan into can.

Questions & Answers
Is this a top or side discharge?
This model uses a side discharge duct connection. It is designed for a 4-inch duct and includes a 4-inch to 3-inch reducer for retrofit applications where a 3-inch duct is already in place.
Is the fan compatible with the Lutron XactSense Humidity Sensor Switch (MS-HS3-WH)?
Yes, the WhisperFit DC fan can be used with the Lutron XactSense™ Humidity Sensor Switch (MS‑HS3‑WH). The humidity sensor can automatically activate the fan when moisture levels rise, helping maintain a comfortable bathroom environment. Thank you for choosing Panasonic!
Can this exhaust fan be installed above shower
does this come with the vent hose
No it does not
Is this fan/light compatible with Lutron Maestro MACL-L3T251-WH? Lutron says no neutral wire is needed.
The WhisperFit DC/LED is compatible with the Lutron Maestro MACL‑L3T251‑WH for dimming the LED light only. That dimmer does not require a neutral, which is fine for the light circuit. The fan motor itself should not be connected to a dimmer. It must be wired to a standard on/off switch or an approved Panasonic fan control. If you’re using separate switches (one for the light, one for the fan), you’re good to go.
FV-0511VQL1 Does the blower motor speed adjust automatically to exhaust vent conditions: 1) roof damper back pressure, 2) vent piping lengths and number of elbows? What should the default blower motor cfm switch be set to: 50, 80 or 110 cfm?
Yes, the FV‑0511VQL1 does include Panasonic SmartFlow® technology. SmartFlow automatically adjusts the blower speed to help maintain the selected airflow, even when installation conditions create added resistance. This includes factors such as: Roof or wall cap backdraft dampers Longer duct runs Multiple elbows or turns The fan continuously monitors static pressure and self‑adjusts within its design range to deliver more consistent CFM than standard fans. What should the Pick‑A‑Flow setting be set to (50 / 80 / 110 CFM)? There isn’t a single default setting — it should be chosen based on bathroom size and usage: 50 CFM – Small bathrooms or powder rooms 80 CFM – Most standard full bathrooms (commonly code‑compliant) 110 CFM – Larger bathrooms or rooms with higher moisture loads (tub/shower, longer run times) Once selected during installation, SmartFlow helps ensure that airflow is maintained as closely as possible to the chosen setting.
Can the fan be wired to run continuously?
We don’t recommend wiring the WhisperFit DC for continuous operation, as the suggested wiring is for use with a switch for spot ventilation. For true continuous or low‑speed operation, a better choice is a multi‑speed model like the Panasonic FV‑0811VSSL1. It wires to a standard switch, and when turned on, it runs at a preset low speed and can boost to high speed when needed.
Is the Panasonic WhisperFit Ceiling Mount Bathroom Exhaust Fan with Dimmable LED Light, model FV-0511VFL1 compatible with Leviton Countdown Timer Switch for bathroom fan and household lights, 10-20-30-60 min, No Neutral Required, model DT160-1LW
Yes, the DT160‑1LW works perfectly for running the FV‑0511VFL1 fan, but the light and night-light require separate switches (a dimmer for the main LED, a standard switch for the night-light).

We’re grateful you stuck with it and are pleased with the performance so far. Thank you for choosing Panasonic, and we hope this fan serves you well for many years to come.
While the Flex-Z Fast™ bracket is designed to simplify installation, we understand that ceiling configurations, tools, and space constraints can make it challenging, especially without attic access. Your comments regarding the instructions, knockout box, and drywall work are very important and have been shared with our product and technical teams for review to help improve future designs and documentation.
We’re glad to hear that the fan itself is performing quietly and effectively. If you need any further assistance with installation tips, troubleshooting, or advice on drywall finishing, please don’t hesitate to reach out to our customer support team. We’re here to help make the rest of the process as smooth as possible.
Thank you again for your honest input and for choosing Panasonic.
Sincerely,
