The Heatco NBK-20691 Draft Inducer is a key component for certain HVAC units, especially gas-fired furnaces and boilers. It operates through an electric motor and fan to safely remove combustion gases and contaminants from the appliance while simultaneously sucking in fresh air for its optimum operation. This approach is essential for maintaining optimal ventilation while decreasing the building up of hazardous pollutants in your living area. The "115V" mark indicates that it runs on conventional 115-volt residence electrical current, while "1 Spd" indicates it has just one speed of operation. Upgrading an outdated draft inducer with the NBK-20691 ensures that your gas-fired HVAC equipment works effectively and securely, encourages proper airflow, and helps to clean the interior environment.
