SERVICE, ENERGIZED
Get high-purity nitrogen, oxygen, carbon dioxide, and calibration gas mixtures for your landfill gas collection, emissions monitoring, and leachate treatment operations.
We offer precise real-time monitoring, mobile alerts, and predictive usage — reduce runouts so you have fewer costly, last-minute deliveries, even during peak gas collection seasons and critical emissions compliance reporting periods.
Get your first delivery within 48 hours in California or Arizona.
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 landfill industry.
H₂
Growing rapidly as a low-carbon fuel for boilers and burners as steam generation facilities seek to reduce carbon emissions. Many existing natural gas boilers can be retrofitted to burn hydrogen or hydrogen-natural gas blends.
N₂
Present as a minor component of raw landfill gas, and also widely used as a delivered industrial gas for purging and inerting landfill gas collection and processing equipment.
CO₂
The second major component of landfill gas, typically making up 40-60% of landfill gas by volume. Must be removed and managed as part of landfill gas processing and RNG production operations.
O₂
Monitored closely in landfill gas collection systems as elevated oxygen levels indicate air intrusion into the collection system, which can create explosive conditions and reduce gas quality.
CH₄
The primary component of landfill gas, produced naturally by the anaerobic decomposition of organic waste in landfills. Typically makes up 45-60% of landfill gas by volume and is either flared, used for energy recovery, or captured for pipeline injection as renewable natural gas (RNG).

Calibration Gas Mixtures — Uniquely, calibration gas mixtures rank as the single most critical category of delivered gases in the landfill industry — unlike virtually every other industry where they play a secondary role. Every permitted landfill is required by federal and state environmental regulations to continuously monitor and report emissions from landfill gas collection systems, flares, energy recovery engines, and facility fence lines. This drives a consistent, high-frequency, non-negotiable demand for methane, CO₂, H₂S, SO₂, and VOC calibration mixtures at every operating landfill regardless of size or gas recovery status.
Nitrogen (N₂) — The highest-volume delivered bulk gas across landfill operations. Used for purging and inerting landfill gas collection and processing equipment, zero gas for emissions monitoring instruments, stripping ammonia from leachate treatment systems, purging groundwater monitoring wells before sampling, pressure testing gas collection pipelines after maintenance, and inerting compressor systems before hot work — making it indispensable across virtually every operational and compliance dimension of landfill management.
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 and natural gas for the power generation industry. 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.
