With and without Stage 1 Vapour Recovery
Stage 2 Vapour Recovery (VR2) controls petrol vapours when a vehicle refuels. It uses a vapour pump and special nozzle (shown) which directs vapours from the car petrol tank back through the hose and into the underground tank.
This reduces petrol vapour emissions by up to 95%. The diagram below shows what happens to petrol vapours during vehicle refuelling with and without VR2 technology.
