General Description

PVC Flexible Duct – 20" (Diameter) * 25ft (Length)


The 20” in diameter PVC duct has a length of 25 feet and is made out of a PVC material. It is able to endure temperatures between -4°F and +176°F. It is built with a steel wire helix frame.

Function
The PVC duct allows air to travel through helix wire-framed ducting, circulating fresh air or removing unwanted air. One end of the flex duct can be attached via strap to a ventilator, and the ducts can be attached to one another, inter-connecting them, using the same strapping method. The PVC fabric of the duct ensures fire-resistance, and the exit end is fortified with a steel collar. The fabric of the duct ensures heat-resistance and can endure aging, burning, and acid.

Applications
The flex duct may be used in any environment with damaging chemicals, especially as floor ducting in a laboratory, or as lightweight ventilation in an attic or basement.

we are looking for approx. 500' of hose, is is available at custom lengths or only 25' pieces? Also, is there a drawstring on each end for mounting to 20'' attachment point?

Custom lengths are available but are made to order and ETA will need to be confirmed. However, due to the easiness of transportation and storage (reduce the risk of damage), the manufacturer suggests that the best way for option is to purchase 20pcs of 25' duct (D1146681) and connect them together. Yes there are drawstrings on each end and we also sell duct clamps as well.

There are draw strings each end. I don't know if they offer custom lengths

DEELAT Industrial offers custom lengths for any of our ducts but they are made to order and ETA would need to be confirmed.

Is there a way to prevent mice from chewing through the pvc flexible ventilation duct. Thank you.

There is really no way to prevent mice/rats from chewing threw the PVC flexible ducts. Mice and Rats can pretty much chew through anything in their path. The only way to prevent it is making sure the area in which the flexible ducting is being installed is eradicated of all mice/rats prior to the installation and have pest control do routine follow ups to make sure they didn't return. This is true for any kind of PVC flexible ducting.

will the 20" with drawstring attach to a 18" fan housing securely or do i need a 18" duct model?

A 20" flexible duct will work on an 18" fan housing but we highly recommend you use our duct clamp sku# D1774888 with the 20 inch ducting.

I have to attach to 20" but want to use 8", how does this get stepped down?

The PVC flexible duct has a pull string that will collapse the end of the duct to shrink down to an 8" diameter. We would also recommend adding a duct clamp to secure it better. Even though you can use the 20" duct and collapse the end to a 8" we highly suggest that you use an 8" duct instead.
