An injector for injecting a flat fan of liquid includes an injector body defining a pair of air channels, with each air channel fluidly connected to a respective air inlet. The air channels join one another at a common throat defined in the injector body and are separated by a land defined in the injector body extending from the air inlets to a point proximate the throat. The air channels and a liquid inlet are in proximity to draw liquid out of the liquid inlet into the throat with air flowing through the air channels. A diverging diffuser is provided in fluid communication with the throat. The diffuser includes an impingement surface defined in the injector body opposed to the liquid inlet. The liquid inlet is configured to inject liquid against the impingement surface to form a fan of liquid diverging outward through the diffuser.
