Allegro 8" x 25' Standard Ventilation Ducting

Allegro 8" Standard Ventilation Ducting is designed for portable blower systems used in confined-space ventilation, utility work, industrial maintenance, construction, manufacturing, and other applications requiring temporary air delivery or extraction. The lightweight, retractable design supports bidirectional airflow with minimal friction loss while remaining easy to transport, deploy, and store.

The single-ply duct is constructed from durable vinyl and polyester materials with a PVC coating and reinforced by a Class 1 hard-drawn spring-steel wire helix. Its non-collapsible design helps maintain the duct opening during operation, while fastening cuffs at both ends provide secure attachment to compatible ventilation equipment or duct connectors.

High-visibility yellow construction with black weather stripping improves visibility around active work areas. The ducting is rated for temperatures from -20°F to 180°F and is designed for rugged field and industrial environments.
