The Danner 12505 pre-filter is designed for compatible mid-range pumps rated from 250 to 700 GPH. A pre-filter like this is useful because it helps catch debris before it reaches the pump, supporting cleaner water flow and making routine maintenance easier on the overall system.

Pre-filters are especially practical when the original unit has become cracked, clogged beyond useful service, or no longer seals correctly. This Danner replacement is a strong option when a compatible pre-filter is needed to help protect a mid-range pump in the 250 to 700 GPH range.

For compatible pump maintenance, this Danner pre-filter is a practical replacement when the original 250 to 700 GPH pre-filter needs renewal.

  • Danner pre-filter for mid-range pumps
  • Designed for compatible 250 to 700 GPH applications
  • Helps catch debris before it reaches the pump
  • Useful for maintenance and repair work
