Pentair Diffuser 1F 1-1/2F 1-1/2A 2A | Challenger High Flow & SuperMax | 355077 C8399 25 HP Pump w/ OmniXThe Pentair Diffuser (355077) is the OEM replacement diffuser for the Pentair Challenger High Flow and SuperMax pump series, sized for 1F, 11 2F, 11 2A, and 2A frame configurations. The diffuser channels water from the impeller into the pump's volute, converting rotational velocity into pressure to maintain consistent flow through your pool or spa circulation system. A cracked or worn diffuser causes pressure loss and reduced pump efficiency this
