Impellers
Impellers interact with HVAC systems by moving fluid or air through the system. They transfer energy from a motor to the air or fluid which is what causes it to move. Impellers are a rotating part of a fan, blower, and pump. Often found in air handling units, centrifugal blowers and exhaust fans, they are made to be durable and provide high-performance airflow....Read more
Impellers are important because they help maintain the system’s efficiency by impacting optimal airflow, air quality, and temperature control. Impellers will suffer wear and tear from debris and high-speed operation. It is important to perform preventative maintenance by inspecting them every 6 to 12 months.
Impeller inspection should include a visual examination by checking the blades for damage such as cracks, corrosion, or imbalance. It is also important to ensure the impeller housing is clean and mounting hardware is secure and tight. In addition, lubricating bearings and removing dust and dirt buildup from the housing and blades is vital. Impeller failure presents as reduced or no airflow. This can cause strain on the motor or overheating.
