EasyPro Pond Products ERPF12E Air Filter Element for ERP Series Compressors.

Pump died - primary problem was start/run capacitor but once that was fixed it was clear that the pump was operating well below capacity. It feeds to air diffuers in a pond that is about 15 feet deep so little air was making it through the diffusers. Got this rebuild kit and it made a huge difference - it's like a brand new pump. Installation instructions could have been a bit clearer and there were some parts that were either unnecessary or that didn't fit, but those were non-issues since the important parts were all there, they fit correctly and made the pump operate like new. Very happy with product and seller.

Factory replacement. Works fine.

Works great in our pond aeration pump

Perfect replacement!
