## Questions & Answers

**Q: who is the maker?**
A: it's a chinese no-brand. It has gotten louder since purchased, and it has a rattle.  The panasonic fan is a better choice and now the only fan I use on remodel projects.

**Q: Does the unit come with a damper?**
A: Yes.  When fan is on the damper opens to exhaust air; when off the damper closes.  To install:  I found that it is easiest to remove all parts; install housing, tape flexible tubing to damper opening, wire electrical, install fan assembly.  If venting to outside, always the right thing to do, install an exhaust cap with flaps.  Unit is very quiet so I also installed a timer in case one forgot to turn off the fan. I am very pleased with this fan.

**Q: Can this be wall mounted?**
A: Yes.  We wall mounted it.

**Q: What is the amperage on this fan?**
A: 0.28 A

## Customer Reviews

### ⭐⭐⭐⭐⭐ love it, I'll come back again for my own ...
*by C***N on November 2, 2017*

I ordered it last week and got it yesterday already for my mom. I installed by myself today, ez set up. It is extremely quiet, just as described. Very fast and efficient shipping procedure. I have never expected buying such product without any pain. But the seller did it! Very ez to install and use! love it, I'll come back again for my own house.

### ⭐⭐⭐⭐ Super quiet. Install in 2 parts.
*by T***X on May 13, 2019*

Today I installed this fan in a bathroom that didn't have an exhaust fan. The fan is extremely quiet and appears to be well made. I feel confident that it will last a long time.As others have stated, the fan as it is shipped is too large to fit through the size hole that the directions specify. That's because the plate that holds the exhaust port and junction box needs to be removed prior to installation. It's as simple as unplugging the power pigtail, removing 2 screws and lifting the plate off of the unit. Cut the 9.5" hole in the ceiling, insert the fan and secure it to whatever framing you have in the attic. Then, in the attic, wire up the junction box and and reinstall on the unit. Connect your duct while you're up there. Back down in the bathroom you still need to reinstall the 2 screws you removed earlier to finish securing the junction box/exhaust plate and reconnect the pigtail.The fan is very quiet so you might consider installing a timing switch so that you don't accidentally leave it running.

### ⭐⭐⭐⭐⭐ Just what I needed!
*by R***R on April 22, 2019*

Had a very loud bathroom fan that this replaced. Had to manipulate ceiling hole to fit as the OEM on the house was 45 years old! Easy to do, however. The noise level is unbelievably quiet! Really, really quite! But it works well!
