Use flexible ducting to ventilate small, confined areas that fans cannot reach. Cheap ducting won't last long, and you may end up paying more in the long run.
When you need low cost, non-collapsible ducting for your air scrubber or dehumidifier, this is the choice for you. Use this 25' long wire-reinforced Mylar flex ducting for all intake and exhaust tasks.
Attaching ducting to your fan provides a simple solution for adding or exhausting air into/out of tight spaces like attics or crawl spaces. This ring will allow for 12" ducting to be added to the Vortex Axial Air Mover and DefendAir EX Air Scrubber.
