Pro-source CED3720-FB Commercial Fan Blade 42in Clockwise

Product Description

The PRO-SOURCE CED3720-FB is a commercial fan blade designed for industrial and commercial air-movement applications. Measuring 42 inches in diameter with a 12mm bore, this blade mounts to standard shaft-driven fan assemblies and moves high volumes of air in demanding environments. Clockwise rotation is fixed, so correct motor shaft orientation is required before installation. At 1 pound, the blade is lightweight relative to its diameter, reducing load on the motor bearing. HVAC technicians and mechanical contractors are the primary installers for this type of component.

This fan blade is suited for commercial HVAC systems, large evaporative coolers, condenser units, and industrial ventilation equipment where a 42-inch diameter blade with a 12mm bore shaft interface is specified. The clockwise rotation pattern makes it appropriate for direct-drive or belt-drive fan assemblies configured for that airflow direction. It is a replacement-grade component intended for service and maintenance work on existing commercial fan systems.

Key Features

• 42-inch blade diameter for high-volume commercial air movement
• 12mm bore for compatibility with standard commercial fan shafts
• Clockwise rotation - verify motor shaft direction before ordering
• Lightweight construction at 1 pound reduces motor bearing stress
• Replacement-grade design for service and maintenance applications

Compatibility

Designed as an OEM-style replacement fan blade for commercial HVAC, ventilation, and air-handling equipment requiring a 42-inch diameter blade with a 12mm bore and clockwise rotation.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified mechanical contractor. Disconnect and lock out all power to the fan assembly before removing the existing blade or handling the replacement. Confirm motor shaft rotation direction matches the clockwise specification of this blade before mounting. Verify bore fit and hub hardware torque requirements against the original equipment manufacturer service documentation for the specific unit being serviced.
