Allegro 9500-25 Duct Hose 25 Ft 8 Inch Blower Compatible

Product Description

The ALLEGRO 9500-25 is a 25-foot duct hose designed for use with Allegro 8-inch blowers in ventilation applications. With an overall diameter of 8 inches and a total length of 25 feet, this hose moves air through confined spaces, tunnels, manholes, and other restricted work areas where fresh air supply or exhaust is required. At 14 pounds, the hose is sturdy enough for demanding jobsite conditions while remaining manageable for a single technician to handle and position. Safety professionals, industrial hygienists, and confined space entry crews are the primary installers of this type of duct assembly.

This duct hose is suited for confined space ventilation setups in both industrial and construction environments. It connects to Allegro 8-inch blower units to deliver or exhaust air in below-grade vaults, utility manholes, tunnels, tanks, and similar enclosed work areas. The 25-foot length provides adequate reach for most standard confined space entry scenarios without requiring multiple hose sections to be joined together, reducing potential airflow loss at connection points.

Key Features

• 25-foot overall length covers typical confined space ventilation distances in a single run
• 8-inch diameter matches standard Allegro blower outlet sizing for a direct fit
• 14-pound construction balances durability with field portability
• Designed specifically for pairing with Allegro 8-inch blower units
• Single-piece length reduces connection points and associated airflow restrictions

Compatibility

Designed for use with Allegro 8-inch blowers. Verify blower outlet diameter before installation to confirm proper fit.

Installation Notes

This duct hose is typically installed by safety technicians or confined space entry supervisors following applicable OSHA confined space ventilation requirements. Inspect the hose for tears, kinks, or collapsed sections before each use, as damage reduces airflow and may compromise worker safety. Secure all blower-to-hose connections firmly before initiating ventilation to prevent disconnection during operation. Do not route the hose through areas where sharp edges or heavy equipment traffic could damage the duct material.
