Emerson 98M19 Condenser Fan Blade 4-blade 18 Inches

Product Description

The EMERSON 98M19 is a 4-blade condenser fan blade assembly designed for use in air-cooled HVAC systems. Built with an 18-inch diameter and a 27-degree blade pitch, it moves air across the condenser coil to facilitate heat rejection. This type of fan blade is a standard replacement component installed by licensed HVAC technicians during condenser service or fan motor changeouts. The blade pitch and diameter are matched to deliver the airflow needed for proper condenser operation in residential and light commercial equipment.

This fan blade is suited for outdoor condenser unit applications where an 18-inch diameter, 27-degree pitch blade is required. It is commonly installed on condenser fan motor shafts in split-system air conditioners and heat pumps. Technicians replacing a failed or damaged blade should verify hub bore size, rotation direction, and blade pitch before installation to ensure proper airflow and motor loading.

Key Features

• 18-inch diameter provides broad airflow coverage across condenser coil surface
• 27-degree blade pitch optimized for condenser fan duty cycles
• 4-blade design balances airflow volume with motor load
• OEM-style replacement geometry for straightforward condenser fan service

Compatibility

Designed as an OEM-style replacement condenser fan blade for HVAC condensing units requiring an 18-inch diameter, 4-blade assembly with a 27-degree pitch. Verify hub bore, shaft size, and rotation direction against existing unit specifications before installation.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect and lock out all electrical power to the condensing unit before removing the fan guard or handling the blade assembly. Confirm blade rotation direction and hub set-screw torque requirements per the equipment manufacturer's service documentation. Improper blade pitch or rotation direction will reduce airflow and can cause compressor or motor damage.
