Air Knives and Air Curtains by Vervo
Air knives and air curtains offered by Vervo are specialized devices designed for industrial applications. A system consisting of air knives (the technical term "air curtain" is also commonly used) ensures high efficiency in operations such as blowing off, drying, cooling, and cleaning with compressed air. Air knives can be successfully used as single units or in multiples installed along a production line.
How Do Vervo’s Air Knives and Air Curtains Work?
Vervo’s air knives and air curtains operate using the Coandă effect. This technology takes advantage of the tendency of an air stream to attach itself to a curved surface rather than moving freely along the direction of flow. Air knives and air curtains produce an air stream with a force precisely matched to the application’s requirements, and they enhance this effect by drawing in “free” ambient air. This makes air knives and air curtains highly efficient and energy-saving for applications like blow-off, cooling, drying, or cleaning.
A properly installed air knife or air curtain can reduce air consumption by up to 50%.
Vervo Air Knives and Air Curtains – Length and Materials
Vervo offers air knives and air curtains in various lengths—including models exceeding one meter. The wide range of sizes allows for precise adaptation to nearly any industrial application involving blow-off, cooling, or pneumatic cleaning. Most air knives and curtains are made from high-quality aluminum (often anodized). For customers with more demanding needs, we offer air knives made from stainless steel, which makes the air curtain highly corrosion-resistant.
