Below 265 SQ/FT Bathroom Ceiling Fan's ?

[Norcal]

I bought a new Panasonic bath fan in anticipation of a planned bath remodel at the ReStore for $65. when the time came, discovered the housing would not fit where it needed to go, so had to spend $120 for a Broan, Feb 2023 will be the 2nd anniversary of the completion, it's super quiet, when roughing in the wiring added a humidistat for the fan, which I recommend also. Recently found a home for the Panasonic fan, for a while thought was going to either leave it on the shelf or donate it back.

I have this one

QT130LE | Broan® 130 CFM Ventilation Fan with Light and Night Light, ENERGY STAR®

Broan® 130 CFM Ventilation Fan with Light and Night Light, ENERGY STAR®

But it vibrates and is annoying at times. I need to get the step ladder out and see why it's making noise. The one I have has heat an night light and a humidity activated switch so it's not quite the same model.

I had one ( not same as yours) that the motor plate was vibrating against the housing of the fan . a bit of silicone around the perimeter and... silence is golden...

I'd highly recommend (if you want a quiet fan, that also moves a lot of air), something like the Terrabloom six inch EC fan. It comes with a few speed controllers and is an EC fan (only uses 33 watts). I'm also using of a few of the AC Infinity inline fans (4") which are also very quiet and only use 20 watts or so. The Terrabloom EC fans have metal housings, so would meet code for kitchen exhaust (fire resistance) and the AC infinity fans have plastic housings, so perhaps better for bathrooms.

You can install these fans inline (in your attic) , and use a duct muffler as well to make it nearly silent. I won't use a built in fan ever again as the inline solutions are much quieter and more efficient at moving air in restrictive ducting where static resistance will dramatically drop actual CFM of a typical bath exhaust fan.

These look interesting.
How did you wire the switch for these.
The controllers that come with them seem to be over kill for a bathroom. I just want on/off. Maybe Timed?

I'm using a zwave switch/relay, (wired in place of the manual switch) so I can control the fan speeds/operation manually or with automation. You can use a dimmer switch (if you want to control the fan speed as well) with 0-10V, or just wire in a switched receptacle and set the speed via the provided speed controller. It will power up at whatever speed it was set to previously.

The simplest setup is just a switched receptacle with the speed controller (has a pretty long remote wire) set at whatever you need.

If you want to control speed and on/off from one switch, read on:

This switch allows you to manually control the EC fan, but also has a zigbee radio so can connect to Hubitat and Smarthings (maybe more) or the Levition Lumina gateway if you are using that system: https://www.leviton.com/en/products/zsd07-adz

This one is "dumb" but will work for manual control: https://www.leviton.com/en/products/ds710-10z

These dimmers have two extra low voltage wires that are there specifically to control 0-10V devices (usually LED lights) that use 0-10V dimming.

Terrabloom includes a harness with breakout wires, so the

Leviton violet wire connects to Terrabloom blue
Leviton grey wire connects to Terrabloom black

The other Terrabloom wires are left disconnected (red and yellow)

Good to know, and make complete sense as the fan was really quiet before I connected the vent. Unfortunately the vent disappears into the ceiling and goes to parts unknown so I can't change it out.

fan was really quiet before I connected the vent.

If you connect a hose, does it actually makes it noisy ?

Don't screw around with nutone ****. Buy a Panasonic. You'll **** yourself over the price, but they run forever, actually pull their rating, and they're quiet.

I'm with Panasonic so far.

Yes, although for a bathroom you don't need the Terrabloom's metal case. I used a Terrabloom 6" fan for my kitchen exhaust specifically as a metal housing is code. They support 0-10V control for these ECM fans, so I use that to ramp the fan with power use on the induction cooktop. This way the fan is on and off via automation, but runs as slow as possible to reduce power use and run as quietly as possible with cooking conditions. AC infinity's inline ECM fans can be controlled the same way via 0-10V.
