Review: Works well in our shop - This works well in our shop. It was easy to install.
Review: Solid construction - This is exactly what we needed. Very simple, solid construction. This may be why the cost is a bit high, not cheap feeling at all. I do wish there was a vent lock for venting without the fan running.

## Questions & Answers

**Q: Can this be used in a greenhouse as an intake shutter near the floor that activates when the exhaust fan near the ceiling runs?**
A: I think it would work, if the shutters are mounted inward.  The flaps work very well, and even by themselves with a light wind.  Don’t expect them to fully open for your application. They will only open enough to break the negative side air created by the exhaust fan.

**Q: I will be using this with out a fan. Does it have a manually propped open option?**
A: No, it takes either negative air or suction pressure to open but you can use your hand to open blades then prop it open if you like.  The intent is to stay closed unless relieving negative pressure .

**Q: Can it be mounted in other than a vertical orientation? I'm looking to install on a diagonal (approximately 45 degree / negative pressure above)**
A: What are you going to use to open it a fan? I would also pay attention to water proofing for a non vertical orientation.. It has one main bus bar that opens all of the louvers at once

**Q: Does the lever on the back attach and move all of the louvers at the same time?**
A: Yes! The lever is attached to all the louvres. I use my fan to open mine I do not have anything attached to the lever. It would be possible to open and close it with an  actuator attached to the lever.

This works well in our shop. It was easy to install.

### ⭐⭐⭐⭐⭐ Solid construction
*by A***R on June 7, 2020*

This is exactly what we needed. Very simple, solid construction. This may be why the cost is a bit high, not cheap feeling at all. I do wish there was a vent lock for venting without the fan running.

### ⭐⭐⭐⭐ Quality and fit is very good.
*by D***8 on April 5, 2021*

For the price, these appear to be well built, installed easy and so far are working fine. I only needed the vents not the fans, so I don't know if the fans are of the same quality.
