Tapping with air gaining popularity in Europe and the USA



 Thanks to the bag-in-ball technology, it’s easy to tap any KeyKeg using air. The multi-layered inner bag provides effective protection by keeping the beverage from exposure to air. Steel kegs and alternative one-way kegs use a spear (or riser), and cannot be tapped with air, since the beverages in these kegs are already exposed to propellant gas or air.

How does it work?

The principle is a simple one. Just attach a compressor to the air hose of the KeyKeg coupler, set the pressure and you’re good to go! You can watch how it’s done in this video. KeyKeg has also tested several compressors and we have found the compressors from Lindr and MGF Compressors to be the best. The KeyKeg partypumps, which also use air, are also selling very well.


Anita Veenendaal, Chief Commercial Officer of KeyKeg, sees sustainability and cost as the main reasons for air-tapping’s success. “A simple compressor can replace an entire CO2 setup. That saves space and money as well. After all, a compressor is a one-time-only purchase, while CO2 bottles are an expensive, and recurring, cost item. Tapping with air is also more environmentally friendly, since you don’t have to fill or transport CO2 bottles any more. We’re noticing that both the cost and the sustainability aspect are reasons for many bars to switch to tapping with air. Another welcome benefit is that there’s also no more dragging and storing those heavy empty CO2 bottles.”

The environmentally friendly one-way keg

We take our environment into account, even during the design phase. A KeyKeg more than meets European Union environmental criteria. The KeyKeg will eventually be made from over 50% recycled PET, and our goal is to recycle every KeyKeg to produce new KeyKegs.
