The Toyotomi Circulation Fan Blade for OM-22, part number 20474171, is a replacement blower wheel designed to fit the circulation fan assembly in Toyotomi OM-22 oil-fired water heaters. It moves conditioned air through the heater’s heat exchanger and into the living space, helping distribute warm air evenly and maintain effective heating performance. This fan blade is manufactured to original equipment specifications so it installs directly into the fan housing when replacing a worn, bent, or damaged blade without modification.
This circulation fan blade is intended for use during service or routine maintenance when the existing blower wheel shows signs of damage, imbalance, or wear that can reduce airflow and decrease circulation efficiency. A properly functioning blade helps maintain the designed airflow rate, reduces stress on the blower motor, and supports consistent warm air delivery throughout the heating cycle. Installation should follow the model’s service instructions to ensure correct seating on the motor shaft and secure attachment to prevent vibration and noise.
What’s Included: One (1) Toyotomi circulation fan blade for OM-22 water heaters.
Installation Limits: For replacement use only on compatible Toyotomi OM-22 heaters; install with the heater powered off and ensure the blade is mounted securely on the motor shaft per the service manual.
