Frequently Asked Questions about Vapor Recovery Units (VRUs)
A VRU, or vapor recovery unit, is a compression system used to collect and compress low volume gas streams for injection into the suction of a larger compressor, a meter run, a local site fuel gas system or directly into a gas gathering line. Mechanical VRUs consist of a driver motor or engine that supplies the power to the compressor.

Stage II Vapor Recovery Petroleum Equipment Institute
Stage II Vapor Recovery. A system designed to capture displaced vapors that emerge from inside a motorist’s fuel tank, when gasoline is dispensed into the tank. Gasoline vapors accumulate in automobile and truck tanks, above the liquid level. When the tanks are filled, the rising liquid forces these vapors to seek an escape route.
