Allegro 9538 Axial Blower 0.33 Hp 115V 8 Inch Explosion Proof

Product Description

The ALLEGRO 9538 is a single-speed, explosion-proof axial blower rated at 0.33 horsepower and 115 volts AC. It delivers 900 cubic feet per minute of airflow through an 8-inch inlet and outlet, making it well suited for ventilating confined spaces, tunnels, manholes, and hazardous work areas where flammable gases or vapors may be present. The polyethylene casing and polypropylene blades resist corrosion and reduce spark risk in explosive atmospheres. At 31 pounds, the unit is portable enough for field deployment while providing the airflow capacity needed for serious confined-space ventilation work.

This blower is designed for use in confined-space entry operations, underground utility vaults, construction tunnels, and industrial areas where air quality control is required before personnel entry. Its explosion-proof rating makes it appropriate for environments where combustible dust or ignitable vapors are a documented hazard. Licensed contractors, safety officers, and industrial hygienists typically deploy this unit as part of a confined-space entry program.

Key Features

• Explosion-proof construction rated for use in hazardous atmospheres
• 900 cubic feet per minute airflow capacity for effective confined-space ventilation
• 8-inch inlet and outlet diameter for compatibility with standard ventilation ducting
• Polyethylene casing provides corrosion resistance and lightweight durability
• Polypropylene blades reduce spark generation risk in volatile environments
• Single-speed, 115-volt AC operation for straightforward field deployment

Compatibility

Designed as a portable, OEM-style axial blower for confined-space ventilation applications requiring explosion-proof certification and an 8-inch duct connection.

Installation Notes

Installation and deployment should be performed by qualified personnel trained in confined-space entry procedures in accordance with applicable OSHA regulations and local safety codes. Verify that the power source is properly grounded and that the supply voltage matches the 115-volt AC rating before energizing the unit. Position the blower to direct fresh air into the space or exhaust contaminated air out, depending on the ventilation strategy required. Do not operate the blower in atmospheres that exceed its rated explosion-proof classification without consulting the manufacturer documentation.
