Allegro 9525 Axial Blower 4650 Cfm 0.5 Hp 115V

Product Description

The ALLEGRO 9525 is a single-speed AC axial blower designed for high-volume air movement in industrial and commercial ventilation applications. Rated at 0.5 horsepower and operating on 115 volts, it delivers 4650 CFM of airflow through a 20-inch inlet and outlet. The blower features a steel casing for durability in demanding job-site environments. It is typically installed by HVAC technicians, industrial ventilation contractors, or safety personnel requiring forced-air ventilation in confined spaces, tunnels, or work areas where fresh air supply and exhaust are critical.

The ALLEGRO 9525 is suited for construction sites, underground work areas, manholes, and similar confined-space or industrial ventilation scenarios. Its single-speed operation and 20-inch duct connection make it compatible with standard flexible ducting used in temporary ventilation setups. The unit ships as an individual piece and is intended for applications where continuous, high-CFM axial airflow is required to maintain safe air quality and temperature control.

Key Features

• Delivers 4650 CFM for high-volume forced-air ventilation
• Single-speed AC motor rated at 0.5 HP running on 115 volts
• 20-inch inlet and outlet diameter compatible with standard ventilation ducting
• Steel casing construction for job-site durability
• Non-explosion-proof configuration for standard ventilation environments

Compatibility

Designed as an OEM-style axial blower for use with 20-inch flexible or rigid ventilation duct systems in confined-space and industrial forced-air ventilation setups.

Installation Notes

Installation should be performed by a qualified ventilation contractor or HVAC technician familiar with confined-space safety requirements. Disconnect and lock out all electrical power before servicing or connecting the blower to any electrical supply. Ensure the power source matches the 115-volt rating before energizing the unit. Duct connections should be secured and inspected for leaks before placing the system into service.
