If you’re comfortable using compressed gas, you might want to consider a five or 10 pound CO2 beverage tank with a CO2 regulator. The CO2 is anhydrous, which means you won’t get any water. And you won’t need a moisture trap. No noise. Wife likes that. Some vendors swap out tanks when you need a refill. In the Chicago area a 5 pound will cost about $25 to charge. You can also buy your tank, but you will need to get a Hydro tested every five years which usually cost about 30 bucks. The CO2 fill usually last me about nine months. The best part is, you won’t get water in your airline. I have owned my tank for 40 years. I had to buy one replacement regulator in that time. If you do get one, just remember to always shut the gas off so you don’t waste any. Voice of experience. Just a thought.
