Allegro 12" x 25' Ventilation Ducting

Allegro 12" x 25' Ventilation Ducting is designed for use with compatible 12-inch portable ventilation blowers in confined spaces, utility vaults, manholes, industrial facilities, construction sites, and other applications requiring temporary forced-air ventilation or extraction.

The lightweight, retractable ducting is constructed from single-ply vinyl/polyester with a durable PVC coating and reinforced with an internal spring-steel wire helix. The non-collapsible design helps maintain the duct opening during operation while allowing the duct to compress for easier transportation and storage.

Integrated attachment straps provide secure connection to compatible 12-inch blowers and ventilation equipment. The high-visibility yellow exterior with black wear strip improves visibility around active work areas and provides additional protection against abrasion during field use.

The ducting is temperature resistant to 180°F and provides a simple way to extend or replace ducting in a portable confined-space ventilation system.
