Master Blower Fan MB-P0813-DCR 8 Inch (Shop 930 CFM Airflow 1/3 HP Motor 115V Single Phase Stackable Housing 25 Foot Ducting Canister Ventilation)

Master MB-P0813-DCR 8-Inch Confined Space Blower Fan with 25-Foot Ducting Canister

The Master MB-P0813-DCR 8-Inch Confined Space Blower Fan with 25-Foot Ducting Canister is an industrial air movement system engineered to purge hazardous gases, stagnant fumes, and airborne dust from enclosed work zones. Powered by a 1/3 HP single-phase electric motor operating on 115V AC power at 60Hz, this 8-inch ventilator generates 930 CFM of volumetric airflow through a dual-walled polyethylene housing. Complete with a tool-free latching storage canister housing 25 feet of flexible ducting, this portable blower solves toxic gas accumulation, inadequate fresh air circulation, and equipment transport challenges across utility manholes, crawl spaces, and industrial storage tanks.

Best Used For:

• Utility Manhole & Vault Ventilation: Supplying continuous fresh air to underground electrical, telecommunication, and municipal sewer access vaults.
• Crawl Space & Attic Fume Extraction: Purging airborne moisture, insulation fibers, and chemical vapors during residential remediation and pipe repairs.
• Industrial Storage Tank Cleaning: Exhausting welding fumes and solvent vapors from enclosed steel tanks and processing vessels during interior maintenance.

Key Performance & Safety Features

• High-Velocity 930 CFM Airflow Delivery: High-output impeller design rapidly exchanges air volumes to maintain OSHA-compliant oxygen levels in confined quarters.
• 1/3 HP Industrial 115V Motor: Energy-efficient single-phase motor runs continuously on standard 115-volt 60Hz jobsite power outlets.
• Dual-Walled Polyethylene Casing: High-density impact-resistant plastic body protects internal fan blades and electrical components from severe jobsite drops.
• Integrated 25-Foot Ducting Canister: Quick-attach canister uses tool-free rubber draw latches to keep flexible ducting clean, compressed, and protected during transport.
• High-Visibility Safety Yellow Shell: Bright safety color maximizes visual detection in dimly lit jobsite environments and heavy traffic zones.
• Stackable Modular Frame Geometry: Molded housing profile enables secure vertical stacking of multiple units to minimize storage footprint in service vans.
