Allegro 9650-25EX Duct Hose 25 Feet Ventilation

Product Description

The ALLEGRO 9650-25EX is a 25-foot duct hose designed for use with Allegro ventilation blowers. It channels fresh air or exhausts fumes in confined space and industrial ventilation setups. The hose connects to compatible blower units to extend airflow reach across jobsite distances that shorter sections cannot cover. At 34 pounds, it is a substantial-length flexible duct solution suited for installation by safety professionals, industrial hygienists, and trade contractors managing air quality in tanks, manholes, tunnels, and other enclosed work areas.

This duct hose is used in confined space entry operations and general industrial ventilation applications. It is paired with Allegro ventilation blowers to supply fresh air to workers or remove hazardous atmospheres. Typical scenarios include utility vault access, sewer work, tank cleaning, and construction site ventilation where continuous airflow must be maintained over an extended run length of 25 feet.

Key Features

• 25-foot length extends blower airflow reach across large or deep confined spaces

Compatibility

Designed for use with Allegro ventilation blowers as stated by the manufacturer. Verify blower outlet diameter matches hose inlet sizing before installation.

Installation Notes

Installation is typically performed by safety professionals or contractors managing confined space entry per OSHA 29 CFR 1910.146 or applicable local regulations. Secure hose connections at both the blower outlet and the confined space entry point to prevent air loss or hose pullout. Inspect the hose for kinks, tears, or blockages before each use. Do not exceed the blower rated airflow capacity for the hose diameter in use.
