Stainless Steel 201 Non Power Roof Ventilator, Wind Turbines Attic Air Vent Ventilating Fan (Size : 110mm)

The media could not be loaded. I was worried because the price was so low but once I received it, I realized it’s great quality. I purchased this for our storm shelter and as you can see, it fits perfect on the roof. All it needs is a little light breeze and it moves easily. We are very pleased with this for circulation of air in our shelter buy one you won’t regret it.

Looks like junk because it is JUNK.

Worked like a charm. Easy installation.

It works great

It doesn't fit over 4 inch pvc.Has to have an adaptor.Oter than that very nicely constructed.

The media could not be loaded. I recently installed this exhaust on my 10x10 shed, and it has proven to be a simple yet highly effective ventilation solution. The spinning mechanism operates smoothly, promoting airflow and preventing the buildup of heat and humidity within the shed.The installation process was straightforward I used a 4in hole cutter to cut my tin roof, and I appreciated the durable construction of the device. It has withstood various weather conditions without any signs of wear or corrosion.Since using this exhaust spinner, I've noticed a significant improvement in air circulation, reducing musty odors and creating a more comfortable environment. It's a cost-effective way to enhance ventilation in smaller spaces like sheds.If you're looking for an affordable and efficient solution to improve airflow in your shed, this exhaust is a practical choice. I'm pleased with the results it has delivered.

This arrived bent. Hopefully it doesn’t impact installation. Will come back to update.Update:: Dented rim made installation a pain in the butt!!! I ended up having to cut wider than the hole with a handsaw in order to get it in there. Now the edges are jagged. It spun once but its low wind today. Will update on a windy day.Update update: will be returning. It doesn’t spin.

Uses as a vent for storm shelterQuality looks good.Price resaonable
