Brew Boss offers a Multi-Filler Kit that allows up to 4 Fill-Boss Fillers to be ganged off a common source. Most commercial operations have from 2 to 4 fillers ganged together to increase production. We have found that we can fill about 2 cases of standard 12 ounce bottles in 20-30 minutes with 2 people and two fillers. One person fills and the other caps, labels, wipes, and places in case. We have a customer filling 22 ounce bomber bottles and they report being able to do 1 case (12 bottles) every 10 minutes with 2 fillers and 2 people.
The only moving part in the filler is the electric solenoid valve. These valves can become plugged if filling beverages with sediment in them. We recommend purchasing the optional inline filter if you are filling beverages with visible sediment. The valves can also become "sticky" if not cleaned properly and routinely. For this reason, we recommend purchasing a few spare solenoid valves (they are easy to change) in the event a valve becomes plugged or sticky and needs to be cleaned. Simply install the spare and clean the valve off-line.
If you need to fill a bottle with a mouth diameter greater than 1.25", you can simply replace the bottle seal we provide with any standard brewery grade drilled rubber stopper. For example, a size 11.5 drilled stopper fits the opening of HydroFlasks perfectly. We don't supply these stoppers, but they can be found at any homebrew or brewery supply retailer or online.
