DESCRIPTION This is a beer filler. It adopts equipressure filling and it doesn't need a power supply. Yet it requires a CO2 cylinder, which is excluded. It is a type of filling machine that is designed to fill beer bottles or cans with a consistent and precise amount of beer, while maintaining a stable and consistent pressure throughout the filling process. This type of filler is commonly used in the beer industry, particularly for microbreweries and craft beer producers who need to fill smaller batches of beer quickly and efficiently.
