Reznor 141570 Ventor Fan Blade

The Reznor 141570 Ventor Fan Blade is an internal airflow component used in Reznor unit-heater ventilation systems. It is mounted on the venter motor assembly to assist the movement of combustion gases through the exhaust pathway. Within HVAC heating equipment, this blade assists in maintaining proper draft conditions required for stable burner performance and heat exchange efficiency. It is commonly replaced during servicing when airflow imbalance, physical damage, or reduced venting performance is observed. The components support consistent exhaust flow in gas-fired heating units used in commercial and industrial spaces, contributing to proper operation of the overall venting and combustion system.
