We are proud to offer standard next day delivery, same-day delivery, and available 24/7 monitoring.
From the first walkthrough to delivery and beyond, our team is always ready to serve.
Our gas experts walk through your setup to build systems that prioritize safety and efficiency.
No matter the volume or type of gas, our state-of-the-art labs and highly-skilled production teams deliver.
Our drivers consistently perform in high-pressure environments and champion things such as customer care, road, and onsite safety.
Stop paying rent on cylinders that aren’t in your possession. And enjoy sustainable service with less deliveries thanks to telemetry’s mobile alerts, real-time measurements, and usage trends.
The days of chasing invoices and updating billing info are gone — access your account and re-order with confidence (and ease).
With WestAir cylinder tracking only pay for the cylinders that you are using. Never overpay for storing empty unused cylinders ever again.
Learn more about the different gases commonly used in the rockets and spacecraft industry.
O₂
Used as an oxidizer in rocket propulsion systems. LOX is essential for the combustion of rocket fuel in space, where there is no atmospheric oxygen.
H₂
Used as a rocket fuel, often in combination with liquid oxygen, in cryogenic rocket engines. This combination provides a high specific impulse, making it efficient for space travel.
N₂
Used for purging and pressurizing fuel and oxidizer tanks, as well as in inerting processes to prevent accidental combustion. Nitrogen gas is also used in spacecraft life support systems to create a breathable atmosphere.
He
Utilized for pressurizing and purging rocket propellant tanks, as it remains in a gaseous state even at cryogenic temperatures. Helium is also used in leak detection and as a coolant in certain applications.
NH₃
Used in some propulsion systems and as a refrigerant in spacecraft thermal control systems.
CO₂
Used in life support systems for removing exhaled CO2 from the cabin atmosphere and in some propulsion technologies.
CH₄
An emerging rocket fuel used in combination with liquid oxygen. Methane offers advantages in terms of storability and ease of production on Mars, making it a candidate for future Mars missions.
Ar
Used as a propellant in some ion and Hall effect thrusters for spacecraft propulsion due to its inert properties.

The rocket and spacecraft industry uses hydrogen and oxygen as rocket propellants, and helium to pressurize fuel tanks and purge systems.
Yes. We offer real-time monitoring for most of our gas applications to make sure you never run out. Our solution provides you (and us) with accurate updates on your levels so we can optimize your gas delivery, detect leaks and other issues – saving you money while supporting our sustainability commitments.
Yes. We make true same-day deliveries with no qualifications. If you call at 4:55 pm and you need a same-day delivery, we will deliver that day.
We offer cost-effective bulk gas solutions including bulk hydrogen, oxygen, and helium for rocket and spacecraft companies. Your products will be safely delivered by our modern fleet of fuel-efficient trucks, equipped for cylinder and bulk gas delivery.
Yes. WestAir barcodes each cylinder and will scan each cylinder when it enters and leaves your location. This eliminates the need for you to perform time-consuming and error-prone inventory tracking. This process also guarantees accurate monthly billing statements.
Yes. Our dedicated account management and 24/7 emergency service is there to make a bad day better.
