This device facilitates the delivery of a pressurized gas stream in a direction counter to the primary flow. An example application would be in cleaning operations where particulate matter needs to be dislodged and removed from a surface. The pressurized gas, often air, is forced backward, creating a localized turbulence that lifts debris away from the target area.
Employing this backward-directed airflow offers several advantages. It minimizes the risk of simply displacing contaminants further along the primary flow path, a common issue with forward-directed air jets. This methodology finds utility in various industrial processes, including filter cleaning, material conveying, and dust control systems. Historically, the need for efficient and targeted cleaning methods in manufacturing and processing plants fueled the development and refinement of this technology.
