desertcart.com : VIVOSUN Z4 4 Inch Inline Duct Fan, 203 CFM Ventilation Fan with Variable Speed Controller for Grow Tent, Indoor Garden Ventilation, Black : Tools & Home Improvement

Review: Great value and performance - Currently using this fan to vent a 40x40 tent with 1 1500w COB LED light. I have found the fan to be well constructed with a thick metal frame and heavy duty power cord. The speed control is large and easy to adjust providing significant control over the fan speed.The sound is noticeable but not over bearing and I found it comparable to other similar fans. The fan has been in use for 4 weeks and so far I have been happy with the output and the cooling ability of the fan and found it to be a great value.
Review: Great value, quiet, plug and play installation. - Fan works great. It’s pretty quiet. Great for a small area where you don’t want too much noise. It’s effective in keeping the temps lower and vents well. The variable speed is a nice feature so it really increases the value since needing any additional controller isn’t necessary. It’s a great bargain and a workhorse. You won’t be disappointed.

## 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?

### ⭐⭐⭐⭐ Good value / not so quiet / higher quality than 190cfm plastic jousting fan
*by B***S on April 8, 2021*

This 203cfm metal housing fan isn’t all that quiet but it is definitely more sturdy and less vibration then the plastic housing 190cfm vivosun inline fan. Overall I am pleased with it. The meta housing 203cfm fan weighs more than the plastic 190cfm and will pull down the top horizontal support bar of any indoor grow tent.
