Allegro 9518-03S Venturi Pneumatic Blower 16.75 in Galvanized

Product Description

The ALLEGRO 9518-03S is a venturi-style pneumatic blower built for industrial ventilation in demanding and hazardous locations. Constructed with a galvanized steel horn and steel housing, this air mover operates on compressed air rather than electricity, making it well-suited for environments where spark risk or electrical hazards are present. The unit measures 16.75 inches in overall length with a 7.31-inch base diameter and 6-inch face diameter. It connects via a 1/2-inch NPT inlet and is rated for a maximum inlet pressure of 100 psi. Air consumption runs 40 CFM at 80 psig and 30 CFM at 60 psig. Industrial maintenance crews and safety personnel rely on this blower for confined space ventilation and fresh-air circulation in high-risk work areas.

This pneumatic blower is designed for use across a wide range of heavy industrial environments. Typical applications include moving air in refineries, utility and power plants, shipyards, paper and pulp plants, the marine and steel industry, and manhole operations. Because it requires only a compressed air source, it can be deployed in locations where electric-powered blowers are restricted or impractical. It is appropriate for both permanent ventilation setups and portable temporary-use scenarios where confined space entry procedures are in effect.

Key Features

• Venturi-style design moves air without electric motors, reducing ignition risk in hazardous locations
• Galvanized steel horn construction resists corrosion in wet or chemically active environments
• 1/2-inch NPT air inlet for straightforward connection to standard compressed air lines
• Rated for maximum inlet pressure of 100 psi with 40 CFM air consumption at 80 psig
• 16.75-inch overall length with 7.31-inch base diameter and 0.4-inch base slot diameter for secure mounting or positioning
• Approved for hazardous location use, suitable for refineries, shipyards, and confined space entry operations

Compatibility

Designed for use in industrial ventilation applications at refineries, utility and power plants, shipyards, paper and pulp plants, the marine and steel industry, and manhole operations where a compressed air supply at up to 100 psi is available.

Installation Notes

Installation and deployment of this pneumatic blower should be performed by qualified industrial maintenance technicians or safety personnel familiar with confined space entry requirements and applicable OSHA standards. Before connecting to a compressed air line, verify that the supply pressure does not exceed the 100 psi maximum inlet rating. Ensure all compressed air fittings and hoses are rated for the operating pressure and are free of damage before use. When used in hazardous or classified locations, follow all applicable local codes and site safety procedures governing air-moving equipment.
