Pro-source CED3705DD-FB 48 Inch Commercial Fan Blade

Product Description

The PRO-SOURCE CED3705DD-FB is a commercial fan blade designed as a direct replacement for industrial and commercial HVAC fan assemblies. With a 48-inch blade diameter and a 12mm bore, this blade delivers high-volume airflow in demanding condenser, cooling tower, or large-unit evaporator fan applications. It rotates in a clockwise direction when viewed from the drive side, which is a critical spec to confirm before installation. HVAC technicians and mechanical contractors handling commercial rooftop units or large split systems are the primary installers of this blade.

This fan blade is suited for commercial HVAC systems requiring a large-diameter, clockwise-rotation replacement blade. Typical applications include commercial condenser fan sections, cooling towers, and industrial air-handling equipment where high-volume axial airflow is required. The 12mm bore accommodates common commercial fan motor shaft sizes found in these systems. Verify shaft diameter, hub configuration, and blade pitch against the existing assembly before ordering.

Key Features

• 48-inch blade diameter for high-volume commercial airflow applications
• 12mm bore designed to fit standard commercial fan motor shafts
• Clockwise rotation - confirm rotation direction against existing assembly before installation
• OEM-style replacement design for commercial fan assemblies
• Packaged individually - sold as a single blade unit

Compatibility

Designed as an OEM-style replacement commercial fan blade for large-diameter axial fan assemblies in commercial HVAC systems. Specific compatible models or part numbers were not provided in the product data. Verify bore size, blade diameter, rotation direction, and pitch angle against the original equipment specifications before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified mechanical contractor. Disconnect and lock out all electrical power to the fan system before removing the existing blade or accessing the motor shaft. Confirm clockwise rotation orientation, bore fit, and blade pitch against the original equipment before mounting. Follow applicable local mechanical codes and manufacturer torque guidelines for hub hardware when securing the blade to the shaft.
