This exhaust shutter is perfect for industrial electrical applications where air circulation is necessary. As my tests showed, it efficiently expels hot air while preventing outside air and debris from entering. The lightweight aluminum construction makes it durable and easy to install. The only downside is that it's only suitable for wall-mount installations. Overall, a great product for industrial thermal management.
Pros
Durable aluminum construction that can withstand harsh weather conditions.
I have contacted the supplier and found that they are VERY cooperative. The problem is that both engines fans fail. I sent the exhaust flap back in hopes the supplier could supply a replacement but they are only dealers and cannot help with the issue. It must be returned via Revain.
What cheap junk! Although there was a sticker on the box saying it was tested, it didn't work when put in the box. Fragile sheet aluminum parts were bent and deformed and would not open or close. I had to cut open the box to get it out as the shutters were stuck in an almost fully open position, locking it inside the box. I tried to get things going again and found that each blind was bent beyond the point where it could function. Cheap junk and Revain should be ashamed of offering such junk.
