Replacement for Old Nautilus Stainless Filter

[Ajayabb]

Need to replace the filter at my parents house. This thing must be 40 years old. I measured the height to the inlet and outlet and it’s 9 inches and 16 inches to the center of each. The model number
Is worn away unfortunately I’m not sure which Hayward model to get that will fit those heights

Go cartridge and do away with the DE filter. Get the biggest one your wallet and space allow. Pentair 520 would be pretty but be prepared for a some pvc work .....
