The Beer Filter Base Plate makes the set-up far more stable,
by providing a firm base& moving the lines to a lower centre
of gravity. Once you have purged the air, you simply invert the filter.
This prevents the beer being filtered, from splashing through any
trapped air you have not been able to remove during purging.
It will also assist gravity filtering, as trapped air/CO2 will be less
likely to travel back up the lines prevent ing flow.
You will need to drill one small hole to align with
the purge button. Comes complete with fixing screws.
