Ruud 70-102345-18 Fan Blade 3-blade 20 Inch

Product Description

The RUUD 70-102345-18 is a 3-blade axial fan blade designed as a direct replacement for residential and commercial HVAC condensing units and air-handling equipment. Built from galvanized steel and aluminum, this blade delivers reliable airflow performance in demanding outdoor and indoor environments. It features a 20-inch overall diameter, a 1/2-inch bore, a 28-degree pitch angle, and clockwise rotation when viewed from the air discharge side. HVAC technicians and contractors install this blade as part of routine condenser fan motor service or system fan assembly replacement.

This fan blade is suited for residential split-system condensing units and light commercial HVAC applications where a 20-inch, 3-blade axial impeller is specified. The galvanized steel and aluminum construction resists corrosion in outdoor installations. The 28-degree pitch and 1/2-inch bore make it compatible with a wide range of standard condenser fan motors. It is commonly installed during fan motor replacements, blade damage repairs, or full fan assembly overhauls on rooftop and ground-mounted equipment.
