Allegro 9650-25 Duct Hose 25 Feet Ventilation

Product Description

The ALLEGRO 9650-25 is a 25-foot duct hose designed for use with Allegro ventilation blowers in confined space and industrial ventilation applications. This flexible duct hose channels fresh air or exhausts contaminated air to and from work areas, extending the effective reach of compatible blower units. At 33 pounds, the hose is built with enough structural integrity to maintain airflow under jobsite conditions. It is a standard accessory component installed by safety professionals, industrial hygienists, and trade contractors who need to move air into or out of manholes, tanks, tunnels, and similar spaces.

This duct hose is suited for confined space entry operations, construction ventilation, and industrial air supply setups where a blower alone cannot reach the work zone. The 25-foot length provides meaningful reach between the blower unit and the target area, reducing the need to reposition equipment during a job. It is commonly used in municipal, utility, and construction environments where OSHA-regulated confined space entry procedures require continuous forced-air ventilation.

Key Features

• 25-foot overall length extends ventilation blower reach into deep or remote confined spaces
• Designed to connect with Allegro ventilation blower systems
• Flexible construction allows routing around obstacles on the jobsite
• Packaged as a single unit with a minimum order quantity of one

Compatibility

Designed for use with Allegro ventilation blowers. Confirm inlet and outlet diameter compatibility with your specific blower model before installation.

Installation Notes

This hose is installed by safety professionals or contractors performing confined space ventilation in compliance with OSHA 29 CFR 1910.146 or applicable regulatory standards. Before connecting or repositioning the hose, ensure the blower is powered off. Route the hose to minimize kinks and sharp bends that restrict airflow. Secure hose connections at both the blower outlet and the entry point to prevent disconnection during operation.
