Allegro 9650-15 Duct Hose 15 Ft 20 Inch Diameter

Product Description

The ALLEGRO 9650-15 is a 15-foot duct hose designed for use with Allegro ventilation blowers in confined space and industrial ventilation applications. Measuring 20 inches in diameter, this hose moves large volumes of air from a blower unit to the work area, providing fresh-air supply or exhaust ventilation as required by the job. At 23 pounds, it is built for repeated field use and can be deployed and stowed efficiently by a single technician. Safety professionals, confined space entry crews, and industrial hygienists specify this hose as part of a complete forced-air ventilation setup.

This duct hose is suited for confined space entry operations, tunnel work, utility vault ventilation, and similar environments where a blower must deliver or exhaust air over a distance. The 15-foot length provides sufficient reach to route airflow from a blower positioned outside a manhole, vault, or enclosure down to the work level. It pairs directly with compatible Allegro ventilation blower units for a complete ventilation train.

Compatibility

Designed for use with Allegro ventilation blowers. Refer to the Allegro blower model documentation to confirm hose diameter and connection fitment before installation.

Installation Notes

Installation and deployment of confined space ventilation equipment is typically performed by safety technicians or contractors trained in confined space entry procedures in accordance with OSHA 29 CFR 1910.146. Ensure the blower is positioned on a stable surface outside the confined space before attaching and routing the duct hose. Inspect the hose for tears, kinks, or connection damage before each use. Do not crimp or sharply bend the hose, as this restricts airflow and reduces ventilation effectiveness.
