Utica-Dunkirk 26589 Blower Wheel 323055-751 whereas standard CCV 3-way valvesThe Utica Dunkirk 26589 Blower Wheel is a critical OEM component engineered for high performance air delivery in Utica and Dunkirk boilers and furnace assemblies. As a precise direct drive blower wheel, this unit is designed to meet strict static pressure requirements, ensuring the inducer or blower motor maintains correct CFM across the heat exchanger. Over time, vibrations or debris buildup can compromise the balance of a centrifugal fan wheel;
