With premium versatility to tackle the broadest range of applications, the ZEVAC QUAD G4 (4th Generation) has built-in multi-pressure capability, with the ability to change pressure differential settings on the fly, from low to medium to high and then high+ (for 100% liquids).

Like all ZEVAC equipment, the QUAD is 100% mechanically driven with no onboard electronics, making it Class I, Div.1 compliant and the safest emissions reduction equipment available for live gas operations.

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