The AI Axis 90 Centrifugal Pump is the largest in AquaIllumination's Axis return pump line, built for bigger systems that still want the quiet DC motor and smart coordination features of the smaller Axis models. Flow rate: ~925 GPH (3500 lph) Max head: ~10ft (3m) Power: variable, 40W max, 100-240VAC input Dimensions: 2.91in diameter x 7.75in tall Nozzle sizes (barbed): 0.75in (20mm) small, 1in (25mm) large — interchangeable for different plumbing setups Coordinated modes: a single button on any connected AI pump can switch all your AI pumps into feed or maintenance mode together Anti-siphon calibration: instead of shutting off completely, the pump keeps spinning without producing flow — this prevents back-siphoning and avoids air bubbles when it resumes normal operation As the top of the Axis line, the 90 is the pick for larger return-pump applications that still want the DC efficiency and quiet operation the Axis series is built around, rather than a bulkier traditional AC return pump.Compatible replacement parts: barbed nozzle sets for the Axis 90.
