## Overview

The Allegro Industries 9500-500 Lay Flat Ducting is a 500-foot long, 2 mil thick clear polyethylene ventilation tube that inflates to 14 inches in diameter. Engineered for flexibility, toughness, and resistance to moisture and chemicals, it’s ideal for temporary air transfer in construction, restoration, and confined space ventilation. Collapsible for easy storage, it fits blowers up to 14 inches and performs reliably across a wide temperature range, backed by Allegro’s 35+ years of industry trust.

## Description

Lightweight air ventilation tubing (similar to a plastic bag) manufactured from durable clear polyethylene, has been engineered for maximum elasticity, flexibility, toughness, and resistance to splitting and tearing. Most commonly used for transferring large volumes of forced air to confined areas, such as water restoration projects, building renovations or other temporary applications. This hose is NOT measured by its internal diameter but rather its diameter when laying flat.

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

## Questions & Answers

**Q: I need a smaller length roll of either 8" or 12" : polyethylene Clear polyethylene 500’ long; 2 mil thickness; 22” (55.8cm) diameter Can you help?**
A: We don't offer a smaller length roll but this is designed to be cut to the lenth you need.  If you only need 200' just roll out that amount and cut, save the rest for later use.

**Q: Seems this should be 22" wide, not diameter, right?  Diameter is 14" max, making a 44" circumference or 2 x 22" (folded flat)**
A: It fit perfectly on my machine that has a 12" discharge. It is 14", not 22" when in the tubular shape.

**Q: Does this come with instructions to mount it on the fan? How it fixed to it?**
A: We simply use duct tape or shrink wrap tape.
A couple small pieces to hold it to the fan and then wrap the circumference.

**Q: Can this be used on runs with bends? How do I secure it so I can ventilate out a window?**
A: It can curve around a corner but probably won't work on a 90 degree bend. As far as securing it, maybe duct tape.
