New 20 cuft Steel Nitrogen Cylinder

A 20 cu ft nitrogen tank is the compact, portable size, standing about 18 inches tall and roughly 5 inches in diameter. At under 14 pounds empty, it is light enough to carry by hand and fits easily in a service bag, van, or under a bench. This makes it a favorite for technicians who need nitrogen on the move.

Yes, a 20 cu ft nitrogen tank is a practical choice for HVAC brazing purge and short pressure tests where portability matters. Dry nitrogen flowing through the lines during brazing prevents oxidation inside the copper. Its small size is easy to carry to a rooftop or crawlspace, though heavy users may prefer a 40 cu ft tank for fewer refills.

No, the cylinder ships on its own, so you will need a separate CGA580 nitrogen regulator and flowmeter to use it. For HVAC purging choose a high-pressure regulator that reaches your test pressure; beverage or lab setups use a low-pressure regulator. The CGA580 outlet is standard, so most nitrogen regulators thread straight on.

Run time depends entirely on the task: a quick HVAC pressure test or brazing purge uses very little, while continuous flow empties it faster. As the smallest common nitrogen size, it is best for short, intermittent jobs rather than long production runs. Watch your regulator gauge and refill before it drops near empty.

Owned nitrogen cylinders start at this 20 cu ft portable size and go up through 40 and 45 cu ft mid sizes to large 300 cu ft cylinders. At 20 cu ft, this tank suits occasional, portable jobs where carrying weight matters more than capacity. Step up to 40 cu ft or larger if you use nitrogen frequently.

Yes, this nitrogen cylinder works for beverage dispensing, tire inflation, and light industrial use in addition to HVAC. Dry nitrogen gives stable tire pressure and clean beverage pours, and the CGA580 valve pairs with the right regulator for each job. Match the regulator to the pressure your application needs.

You own this cylinder outright once purchased, with no rental contract or recurring fees. Ownership lets you refill or exchange it at any qualified gas supplier rather than being tied to one vendor. Keep your purchase and hydro-test records to prove ownership at exchange.

Any welding or industrial gas supplier that carries nitrogen can refill this CGA580 cylinder, and refill cost varies by region and purity. Because you own the tank, you can compare prices between suppliers rather than paying rental. Call ahead, since some suppliers exchange small cylinders rather than filling on the spot.

Yes, “nitrogen tank,” “nitrogen cylinder,” and “nitrogen bottle” all describe the same steel container that stores compressed nitrogen. This 20 cu ft nitrogen cylinder holds dry nitrogen at high pressure for HVAC, beverage, and industrial use. Whichever term your supplier uses, the CGA580 connection is the same.

No, all cylinders ship empty for transport safety, so this tank must be filled before use. Take it to a gas supplier that can provide nitrogen and fill to the marked service pressure. Once filled and fitted with a CGA580 regulator, it is ready for HVAC brazing, beverage, or industrial work
