Overflow Filter

A 304 stainless, 600-micron filter that helps stop grain particles entering a Grainfather overflow pipe.

Compatibility and fitting

Fits between the overflow inlet and top mash plate; it has a 23mm centre hole. Confirm compatibility with your Grainfather model.

Helpful information

Assemble before mashing and clean the mesh promptly after use so particles do not dry into it.

Check the overflow assembly first

This filter suits compatible Grainfather systems that use an overflow inlet and top mash plate. It is not intended for the current G30v3 basket design, which does not use additional pipework. For small-batch brewing on a compatible older system, also see the Micro Pipework; confirm both parts against the exact Grainfather generation before ordering.
