## Questions & Answers

**Q: 50db seriously?**
A: Louder than I thought too.  Have a muffler and an enclosure made from 2" fiberglass ceiling tiles...back looking for something else.

**Q: How loud is this fan?**
A: Best value for the money...If you have ever lived anywhere that had A/C compressors outside of your window...it's as loud as that. Yes, what you here is more the whooshing from the air movement than the fan motor. Too help with that...I ran my exhaust tubing to the back of the tent...away from the door...helped a lot.. Also; there is no "hum" in this controller whatsoever. A problem I had with another brand. Hung motor using HD zip ties...stopping any potential vibration...This fan is also very strong...I have to run it as low as it goes...more than enough...kinda too much for the 2 X 4 X 6. As a kicker...Vivosun has been around for a long time and have always treated me right.BUY IT it you'll like it!....

**Q: Is it discret shipping?**
A: No discrete shipping. The box has Vivosun's name and inline fan all over the box. Amazon doesn't tell you that. They do on some things but this isn't one of them.

**Q: How many watts would this fan use running it at say half volume using the included controller?**
A: If the information for the electrical rating is correct as stated.  The fan at full speed draws 1.1 amps.  That would be 132 watts at full speed so one could conclude an approximate watt draw of 66 watts.  But electricity being what it is and the construction of the component parts I believe you could safely say 75-100 watts.  May I ask why you are concerned with the watts?
