Stainless Steel Counter Pressure Filler

Stainless steel counter pressure bottle filler for filling carbonated beverages from a keg into bottles.

The bottles are filled from the bottom up, in an oxygen-free environment. The CO2 back pressure in the bottle prevents the beer from foaming.
Works best with cold liquids at a pressure between 0.6-1.1 bar.

Hose barbs for beer and CO2: 6 mm
1/4'' BSP thread beneath the hose barbs offers the possibility to replace them with JG 3/8" - 1/4" BSP. (1/4" NPT also creates a good seal, but may damage the threads if overtightened, due to the conical shape of its threads). Teflon tape is recommended on threaded parts.

The ball valve has three positions: Gas on - Liquid on - Off.
The pressure relief valve is manually adjustable and allows fine tuning the filling rate.

First, CO2 is added to the bottle to form an overpressure / back pressure. Remaining air is vented through the pressure relief valve.
When the main valve is turned, the gas supply closes and the beer line opens. The back pressure in the bottle causes the bottle to fill at a slow pace with moderate foaming.
When the bottle is full, shut off the flow by turning the valve to the Off position. After a few seconds the overpressure has vented and the bottle can be capped on foam.

Fits bottles with minimum height 22 cm and 14 - 20 mm bottle mouth. For higher bottles, a piece of tubing may be added as an extension to reach the bottom.

We recommend CIP (Clean In Place) with PBW or Enzybrew after use, followed by thourough rinsing with water.
Use Star San, Saniclean or similar sanitizer before the next filling session.

Silicone stopper 22/17 mm included.
Larger silicone stoppers can be purchased for use with growlers and other larger-sized bottles.
