The Patterson PB34B High Velocity Fan is a large-diameter, direct-drive ventilation solution designed for demanding industrial settings such as warehouses, manufacturing floors, and shipping/receiving areas. With a 34-inch propeller and a compact footprint, this unit delivers high-volume air movement over long distances to improve air circulation, help with condensation control, and provide targeted cooling where workers are stationed or moving along aisles and workstations.
Construction combines a high-impact polypropylene housing with heavy-gauge steel, reinforced for durability in rugged environments. The patented Venturi-designed barrels and side air intakes optimize airflow projection and entrainment, enabling effective coverage up to about 230 feet from the source. The fan uses maintenance-free, direct-drive motors with sealed bearings and a totally enclosed design, reducing downtime and service requirements. It accommodates multiple voltages from 115V to 460V, with options for variable-speed motors in the 14"–22" range, and there are eight mounting configurations to fit a variety of facility layouts. OSHA-compliant steel finger guards add a layer of operator protection where needed.
This model ships without a cord and includes a robust set of mounting and installation options to suit fixed or portable configurations. Its performance specifications—up to 17,000 CFM, 3 HP, 1200 RPM, and a sound level around 88 dB at 20 feet—reflect its role as a high-velocity contributor to improved air movement in larger spaces. When planning use, consider the power requirements, mounting geometry, and appropriate guarding to ensure compliant, effective ventilation in your specific application.
