Davey - ProMatic ESC 36/48 Mains Input Filter - 2212E

Davey – ProMatic ESC 36/48 Mains Input Filter (2212E)

This is the genuine Davey replacement mains input filter for the ProMatic ESC 36 and ESC 48 salt water chlorinator power supply units. Fitted inside the power supply housing, it suppresses electrical interference on the incoming mains supply, protecting the controller electronics and ensuring stable, reliable chlorine production. It is typically replaced when the power supply unit shows signs of electrical interference, erratic behaviour, or following an internal PCB inspection by a qualified technician.

Compatibility

This input filter is specific to the Davey ProMatic ESC 36 and ESC 48 models (also sold under the Monarch Pool Systems brand in Europe). It is not interchangeable with parts for the smaller ESC 16 or ESC 24 units, the ESR series, or the MPS series. Always verify your exact model designation before ordering. Note: this part is listed as available while stocks last — a limited end-of-line spare.

Why genuine matters

The ProMatic ESC power supply unit operates at mains voltage and the input filter plays a critical role in protecting sensitive PCB components from voltage spikes and conducted EMI. Using a genuine Davey part ensures correct electrical ratings, a precise physical fit within the enclosure, and compliance with the original design specification — safeguarding both the unit and its warranty.

Installation

Replacement of this internal component requires the power supply enclosure to be opened and should only be carried out by a suitably qualified electrician or authorised Davey service technician. Always disconnect the unit from the mains supply before any work is performed. Refer to the ProMatic ESR/ESC Installation and Operating Instructions for full servicing guidance.
