Allegro 9538-15 Axial Blower Kit 900 Cfm 8 Inch

Product Description

The ALLEGRO 9538-15 is an AC-powered axial blower kit rated at 900 CFM, designed for ventilating confined spaces such as manholes, vaults, tanks, and tunnels. The kit runs on 115 volts AC and delivers 0.33 HP to move air through an 8-inch inlet and outlet. The blower canister is constructed from polyethylene for durability in rugged field conditions. This unit carries ETL certification and is explosion-proof, making it appropriate for environments where flammable gases or vapors may be present. The kit ships complete with a 15-foot vinyl and polyester duct, allowing immediate deployment without sourcing additional components.

This blower kit is used in industrial and utility applications where fresh-air supply or exhaust ventilation is required in permit-required confined spaces. Typical users include utility crews, industrial safety personnel, and contractors working in below-grade or enclosed environments. The 8-inch duct diameter supports adequate airflow volume for standard confined space entry scenarios. The explosion-proof rating makes it suitable for petrochemical, wastewater, and similar worksites where ignition risk must be controlled.

Key Features

• 900 CFM axial airflow output suitable for confined space ventilation
• Explosion-proof rated for use in hazardous atmospheres
• ETL certified to applicable safety standards
• Includes 15-foot vinyl and polyester duct for immediate use
• 8-inch inlet and outlet diameter for high-volume air movement
• Polyethylene blower canister for impact and corrosion resistance

Compatibility

Designed as a standalone confined space ventilation kit suitable for use with standard 8-inch flexible duct systems in industrial, utility, and contractor applications requiring AC-powered axial ventilation.

Installation Notes

This blower kit is typically deployed by industrial safety technicians or utility contractors following confined space entry procedures under OSHA 29 CFR 1910.146 or applicable site safety plans. Before placing the blower, verify the power source is a grounded 115-volt AC circuit rated for the load. Position the blower at the entry point and route the duct to direct fresh air toward the worker or to exhaust contaminated air away from the space. Do not operate in standing water or modify the explosion-proof canister housing in any way, as doing so voids the ETL certification and creates ignition risk.
