Carrier LA21RA426 Blower Wheel 4 1/4 " Dia 3 " W CW 5/16 "

The Carrier LA21RA426 Blower Wheel is a necessary part in HVAC systems for air circulation. The 4-" diameter, 3-" wide impeller rotates clockwise (CW) with a 5/16-" bore for secure attachment to the motor shaft. The motor spinning the impeller pushes air through a whole HVAC system efficiently, continuously forcing air forward until there is suitably smooth airflow to achieve the desired heating or cooling. The ability to move conditioned air efficiently through your living space is essential to overall comfort and system performance so it can completely distribute air where you need it.
