For its assembly, the original bulkhead with m14x1 thread is used

Before purchasing, you must check whether the original Grainfather bulkhead is the correct size

If your Grainfather has an incompatible bulkhead, it must be purchased separately

New filter that replaces the original internal filter of the Grainfather. The problem with the original filter is that if it becomes clogged, the flow decreases considerably, sometimes even reaching total blockage, significantly lowering efficiency, it is also a filter that paradoxically does not filter. In fact, it often happens that coarse parts are not blocked and once they enter the pump impeller they even risk blocking it. If this happens it is a big problem as there is no possibility to disassemble it being directly connected to the vat and the vat is full of must.

With this new filter all this does not happen. The filter has been specifically designed in BacBrewing in such a way as to make it even removable and cleanable with a full pot.

The article is composed of all the parts necessary to obtain the complete external filtering system

Filter cylinder with 400 or 800 microns of your choice weave obtained from electro-pointed micro-perforated sheet, not mesh.

External cylinder in pyrex borosilicate glass thickness 5 mm

Totally disassemblable, totally built in pickled stainless steel, electropolished and passivated with acids that comply with the most severe USA ASTM 380-967 directive and with materials and procedures that comply with EU MOCA regulations, all welding is performed in Argon TIG.

All silicone parts are made internally in BacBrewing and are FDA certified food grade with resistance from -50 to + 180 ° C

Changes / improvements made

1- Increased diameter of the cap fins brought from 16 to 16.5mm in diameter for a greater guarantee of sealing.

To insert it it is recommended to wet it. Operate it linearly, DO NOT rotate on itself for risk of breakage

2- The hose clamp for the pump hose in the photos is no longer produced in the UK but in Taiwan and has a very bad quality. For this reason the double wire clamp is supplied 

3- Replacement of the silicone gasket of the central screw with an analogue in Teflon to be able to apply greater closing force to the gaskets of the Pyrex cylinder

4- Replacement of the vent screw with knurled screw for greater ease of operation when venting without the use of a screwdriver


5- Replacement of the silicone seal of the bulkhead from silicone to teflon for a greater fixing force of the filter to the Grinfather 

6- Pyrex cylinders with re-burned edge for greater mechanical resistance
