The double blower wheel is a key component in HVAC systems, designed to facilitate efficient air movement within heating, ventilation, and air conditioning units. With a diameter of 3.4 inches and a width of 4.5 inches, this blower wheel is engineered for compact systems requiring high airflow in limited space. Its reversible design allows for flexible installation in either clockwise or counterclockwise rotation, making it suitable for a wide range of HVAC configurations.
