Regal Rexnord - Fasco 4CR1633-4 Fan Blade 16" DIA

The Regal Rexnord - Fasco 4CR1633-4 Fan Blade is a condenser fan blade used in outdoor units to move air across the condenser coil for heat rejection. It is a 16-inch aluminum blade with a 33-degree pitch and a 1/2-inch bore hub, designed for clockwise rotations, and direct mounting on compatible motor shafts. It is installed in air conditioning condensers, heat pumps and rooftop equipment, where it maintains the airflow through the coil to support efficient refrigerant cooling and system pressure balance. The geometry is designed to deliver stable airflow and consistent performance under continuous outdoor operating conditions in applications.
