tempory air ducting
Great for creating a negative pressure area in a house when used with floor blowers. We use several air floor blowers to create the negative pressure within an area so that when we are doing sheet rock sanding or painting that the fumes or the air particles are removed from the area instead of spreading through out the area with the internal air system.

Worked Good
Ran about 200 ft from the blower and it worked good. much cheaper than 200 ft of pipe or collapsible duct.

It came dusty and open
The product itself is probably good enough to do temporary ducting but if you buy something new you expect a new product. It came partially unrolled and very dusty.

I got this ducting for stock & have not yet used any of it. It appears to be adequate for our negative air machine that we use in occupied buildings that have strict dust policies such as hospitals.
