air conditioner condenser: Panasonic FV-20NLF1 WhisperLine 240 CFM In-Line Fan, 6-Inch Duct

Product Description

FV-20NLF1 The Panasonic WhisperLine in-line 240 CFM bathroom fan is 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 bathroom fan, which removes ''stale'' air and provides fresh air on a slow, continuous basis.

Is it running, my wife asked. Seriously, this is a high quality, silent running, mass air moving bathroom fan. I paired this up with the "Panasonic PC-NLF06D WhisperLine Accessory Kit, 6-Inch Double Pick Up Panasonic" and installed 2 vents in my master bathroom. The accessory kit includes everything you need, sans 6" flex duct to run between the vents and the unit and then from the unit to the outside. The accessory kit includes a damper for each vent location and is completely silence when the dampers open and close. Overall, this unit appears to be well constructed and should provide many decades of use.

I found this simple formula online to calculated the required CFM for your bathroom. It seems to be spot on.

Step 1: Calculate the cubic feet of your bathroom (length x width x height)
Step 2: Divide by 60 (the number of minutes in an hour)
Step 3: Multiply the result by 8 (the number of recommended air changes per hour)
== recommend CFM

Quietest kitchen fan yet, April 9, 2008

Jerome Mcintire "God is bigger than that" (Viroqua, WI United States) - See all my reviews

We have renovated several houses and have always installed Panasonic vent fans. They are among the quietest and most durable available (Fantech is also good). This is the first inline fan we have installed. We put it in the kitchen-- we don't need a fancy hood with fan over the stove, just a good exhaust fan to clear the occasional smoke or to cool the room. This fan moves lots of air (240 cfm), especially with the 6" duct we installed, but it is quieter than the 70 cfm ceiling fans we have put in previously.

Great fan. I have been looking for years., August 13, 2010

I have been looking for years to find a replacement for the noisy cobbled exhaust fan the builder put in my attic to vent 3 bathrooms and the laundry room. Amazon is the last place I would consider to look for something like this. I only found it while I was looking for something else. I'd rather be lucky than smart.

This unit is quiet and easy to install. Their installation methods and hardware are very flexible. The 240 CFM size is adequate to exhaust four room outlets of 4" diameter each with major restrictors at the room outlets. I have the fan on a timer that runs 16 hours a day. The inlet of the fan unit is only a single 6" opening. You must construct your own inlet plenum for multiple inlet connections. A Y-connector or a T-connector works nicely.
