Emerson 72L70 3-blade Fan Blade 18 in Cw 22 Degree

Product Description

The EMERSON 72L70 is a 3-blade axial fan blade designed for use in HVAC condenser and evaporator fan assemblies. Measuring 18 inches in diameter with a 22-degree blade pitch and clockwise rotation, this fan blade moves air efficiently through condensing units and air handlers. The fixed-pitch, multi-blade design suits direct-drive and belt-drive fan motor assemblies common in residential and light commercial HVAC equipment. Licensed HVAC technicians and refrigeration mechanics typically handle replacement of this component during routine maintenance or motor swap-outs.

This fan blade is suited for outdoor condensing units, rooftop units, and similar HVAC equipment that require a clockwise-rotating axial fan. The 18-inch diameter and 22-degree pitch make it a common fit for mid-range condenser fan assemblies found in residential split systems and package units. It is installed on the fan motor shaft and secured with a hub and set screw arrangement standard to this blade class.

Key Features

• 18-inch diameter for mid-range condenser and evaporator fan applications
• 22-degree blade pitch optimized for axial airflow in HVAC equipment
• Clockwise (CW) rotation matches standard condenser fan motor shaft configurations
• 3-blade design balances airflow volume with motor load
• OEM-style replacement geometry for straightforward swap-out

Compatibility

Designed as an OEM-style replacement fan blade for residential and light commercial HVAC condenser fan assemblies requiring an 18-inch, 3-blade, clockwise, 22-degree-pitch axial fan blade.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the unit before removing the fan blade assembly. Ensure the replacement blade pitch direction and rotation match the original before securing the hub to the motor shaft. Verify set screw torque and blade tip clearance per the equipment manufacturer's service documentation before returning the unit to operation.
