ZEVAC Quad

Ultimate Versatility for Heavy Applications

Still portable enough to be transported on a flatbed or trailer, the Quad is the ideal combination of form, fit, and function

Engineered for maximum versatility in the field, the ZEVAC Quad G4 (4th Generation) is built to handle the widest range of gas and liquid recovery scenarios with a single unit. Its integrated multi-pressure capability lets your crew adjust pressure differential settings in real time, from low to medium to high and up to high+ for 100% liquid recovery, so you can match changing conditions, maintain control, and keep operations moving without swapping equipment or breaking down the setup.

Like all ZEVAC equipment, the Quad is 100% mechanically driven with no onboard electronics, delivering safe, reliable emissions reduction for live gas operations. With no ignition sources, complex controls, or onsite power requirements, it helps you maintain compliance while eliminating routine venting and flaring. Compact and portable enough for flatbed or trailer transport, the Quad enables your crews to safely recover gas and liquids, reduce methane emissions, and keep operations online with confidence.

Meet Compliance
Cross compression keeps gas from entering the atmosphere, maintaining compliance with emission regulations.
Reduce Risk
By keeping gas in the pipes, risks related to venting and flaring are completely eliminated.
Easy Integration
ZEVAC equipment easily connects to gas lines and pipes, allowing for quick setup and operation.
No Electricity Required
Driven by compressed air, ZEVAC equipment requires no electricity to operate.

Customer Success Story:

Frequently Asked Questions

What is the Quad commonly used for?

The ZEVAC Quad unit is most commonly used for distribution, spools, upstream, midstream, and all traps. It will operate on gas and any Y-grade liquid, butane, propane, NGL. As well as a mixture of both gas and liquid.

What air supply does the Quad use?
The ZEVAC Quad operates using 4 individual cores, each requiring 90 cfm. To run the Quad at full power, a 375 cfm or higher air compressor is recommended.
How can I transport a ZEVAC Quad?
The Quad is the largest of the ZEVAC lineup but is still mobile and versatile. Operators typically delpoy the Quad via flatbed truck or trailer depending on the project needs and jobsite conditions.
How far can the Quad draw down to?
Like all ZEVAC equipment, the ZEVAC Mini can draw down pipelines to 0 psi. This removes any and all product, both liquids and gases, from the pipeline.
What is cross compression?
Cross compression is the process of vacuuming natural gas out of a pipeline section that needs to be depressurized and recompressing it back into another section of the system, keeping product in the pipe instead of releasing it into the atmosphere. ZEVAC's patented, portable cross-compression equipment is the only proven solution on the market capable of handling everything from 100% dry gas to 100% liquid contents, making it the industry's most versatile gas and liquid capture and recovery technology.
Why use a ZEVAC?
 

Here's what ZEVAC cross compression delivers:

  • Regulatory compliance — Supports OOOOb/c and EPA methane mitigation requirements, helping you stay ahead of evolving regulations.

  • Enhanced crew safety — Keeps product inside the pipeline, significantly reducing ignition risk and exposure hazards for your team and surrounding community.

  • Zero product loss — Recovered gas stays in your system, eliminating waste and protecting revenue.

  • Environmental stewardship — Eliminates routine venting and flaring, reducing methane emissions and advancing your ESG and net-zero goals.

 
Can ZEVAC handle liquids?
ZEVAC is a positive displacement linear compressor. This means there is no spinning crankshaft or rotating drivetrain, which affords the ZEVAC equipment unique functionality and advantages, such as the capability to capture and recover product contents from 100% dry gas; to any percentage of wet gas mixtures; and even up to 100% liquid service. 
How can I get a ZEVAC?
ZEVAC equipment is available in a variety of options, including rent; purchase; and a lease-to-own program.
