The Patterson Fan PB22B is a high-velocity, pedestal-style air mover designed for demanding factory and warehouse environments. With a 21-inch (nominal) three-blade propeller and a venturi-designed barrel, this unit concentrates and directs airflow to improve circulation, help with ventilation in aisles, workstations, and staging areas, and support employee comfort in hot or stuffy spaces. Its 1/2 HP direct-drive motor powers a robust airflow while providing long-lasting sealed bearings in a maintenance-free design. Construction combines a high-impact polypropylene fan housing with heavy-gauge steel, and it features OSHA-compliant finger guards to help meet shop-floor safety requirements. The PB22B is capable of operating across a broad voltage range (115V–460V) and can be configured with multiple mounting options, with optional oscillator kits available to broaden its coverage.
Key details matter for selecting this unit: the fan offers an impressive air throw and wide coverage suitable for large work cells or open areas, with a rated velocity that supports air movement up to 100 feet. The unit ships without a cord, but models are documented with a 12-foot cord on 115V versions where applicable. A maintenance-free, direct-drive motor is designed for reliability in continuous operation, and the 2-year warranty provides a measured level of protection after purchase. When evaluating placements, consider the 3600 ft² effective coverage and 66.5–77.6 dB operating range at typical distances to balance noise with cooling performance.
