That cylinder of nitrogen in your back room has come a long long way before you laid hands on it! Did you know the nitrogen inside has seen more miles and consumed more energy than you would ever suspect?!
The nitrogen inside that high pressure cylinder started life as a gas molecule somewhere far away. A large industrial plant turned that nitrogen gas molecule (and a bunch of their friends) into liquid nitrogen at the expense of a whole lot of energy. Once liquid, nitrogen must be kept very cold to limit the loss of liquid back into gas again at the expense of even more energy.
This is just the beginning of the journey for that original nitrogen gas molecule. From there that liquid nitrogen is transported down local highways to smaller plants and eventually smaller tanker trucks all the while consuming more energy. Those smaller industrial plants then use large amounts of energy to heat up the liquid nitrogen back into high pressure gas cylinders. Those cylinders are then transported by cylinder trucks that eventually will deliver you that original nitrogen gas molecule.... at the expense of even more energy :/
Nitrogen cylinders....What a trip!
The most obvious benefit of on-site nitrogen blending is you simply get a higher quality product. Blended nitrogen allows you to draw the beverage directly from the keg, through the tap, and into the glass without waste in the form of flat or foamy beer.
The result is a delicious beverage that matches a brewer’s vision, a better drinking experience and most importantly, a request for a second glass!
On average, purchasing delivered nitrogen is about the same cost as renting an environmental nitrogen separator. Besides the convenience of using Touch Free Nitrogen™ and reducing your carbon footprint the biggest advantage in cost is applying the correct gas blend to your keg room.
The cost difference in perfectly carbonated beer vs flat and foamy beer dwarfs any gas costs.
Offering an option for both wall mounting and roll-in-place solutions, Green Air Supply has developed the most eco-friendly and financially sustainable nitrogen systems on the market today.

What size GAS separator do I need?
There are multiple factors that will get us to this answer. The short answer is with another question. How many kegs do you go through each month? 0 - 200? A medium is the unit for you. 0 - 350? A large is the unit for you. 0 - more than 350? You need a large plus.
The other factor may help as well. How many bartenders do you have pouring beer at any one time? 1? A medium is the one. 1 - 2? A large. 1 - 3 and some bar backs? A large plus.
What else do I need to get my draught system up and running?
CO2. And the draught system, of course. CO2 is a commodity, so you can get that anywhere. Shop around. Talk to your neighboring establishments and get some recommendations. Some gas suppliers are amazing, but others are lacking. Everything else that a draught tech will need is included in the package. When it comes to the draught system, we can make some suggestions depending on your location. Please shoot us an email and we can help you out.
How much power does the separator draw?
6 amps. A normal 110 volt outlet is sufficient. We do suggest a dedicated outlet (not GFI) that is not switchable.
What blend do I need?
The answer to this question is easy, as long as you know about your draught system. The draught tech that is designing/installing the system will have all of the answers. A draught system is a delicate balance of pressure and resistance. The intention is to keep the beer exactly as it was brewed and kegged. The pressure applied to the keg should encounter the exact same amount of resistance when it leaves the keg. This will result in a perfect pour every time.
We don’t pour any nitro beers. Why do I need this system?
Short draw system vs. long draw system. If your kegs are in the cooler directly below your faucets, you can probably use only CO2 to push your beers. If your kegs are in a cooler located remotely in reference to your faucets, CO2 will create too much foam. CO2, as a gas, will break out in solution, if it is allowed to have too much contact with water. Beer has a lot of water as an ingredient. The CO2, when exposed freely to this liquid will form carbonic acid, which is not good for the beer. When CO2 is blended with nitrogen (N2) under the correct pressure, it is not given the opportunity to break out. The nitrogen helps keep the pressure on the liquid, which prevents the CO2 from bubbling, foaming, and just being an issue all together. All of your beers will benefit from a specific blend of CO2 and N2 to allow you to get every drop of beer (and dollar) out of each and every keg.
Can you sell me CO2?
The short answer is no. However, we can refer you to some wonderful companies around the country that will sell you CO2.
