Air Scrubber Duct Source?


I'm looking for options for hooking up negative air to a blu-dri air scrubber. There are a few options for 8" x 25' collapsible wire reinforced duct. They run about $70 and up. Does anyone have a lead on anything that costs less? Seems kind of pricey for a 25' duct. I was also looking into using the poly style duct that abatement contractors use. But that stuff isn't exactly cheap either. FYI, it seems like amazon is taking over the world. Thanks, Nick.

Unless the poly duct is going straight it is terrible, kinking and flopping around. It only seems to work straight

This is a bit less expensive but I doubt it would last very long if it gets moved around a lot. $25 as opossed to $75, probably fine for a one shot job.

8" poly I found @ about $0.38/foot. But it comes with the kink issues.

Product is called layflat & yes you have to tape securely - one trick I heard is cutting a 5 gallon bucket in 3 & using the top two pieces as a locking collar & fitting that through your barrier or window

I'll run it on top of firring strips, then wrap with packing wrap in a few places. Just more messing around....

Re: Air Scrubber Duct Source?


I found some that didn’t seem too bad. I’ve got to think the lay flat moves air better than the corrugated duct. But it is disposable. The asbestos guys I just had on my job ran some lay flat over 40’ to get the negative air to work. It wasn’t straight but it seemed to work pretty well. I’ve never used it so it will be a bit of a learning curve. Tying off the end seems to be a requirement to get it to fill up. And then I’ll have to experiment with how many holes to put in the end to get it to move air but still stay expanded.

We've used tons of the poly tube on projects in hospitals. Roll it to where you intend to exhaust it to & tie a knot in the end. Cut holes as needed to allow for the airflow while maintaining the integrity of the tube

What mill thickness was the poly you used. Ive only got a 8 scrubber, so I went light on the stuff I got. 2 mil. Hopefully not too light. A lot of it seemed to be 4 mil.

We use this. Just cut to length and run it where you need it. If it is too long it gets a little out of hand.

I believe we use the 4 mil stuff. Almost all of our air scrubbers have a 12" outlet
