Air Knives


Vortec Air Knives

Air Knives deliver sheets of amplified, uniform air, powerful enough to remove liquid and debris from the surfaces of wide objects. Air Knives only require a small amount of filtered compressed air as they are air amplifiers, producing 25 times the amount of air amplification compared to compressed air alone.

The air sheets produced by our Air Knives are high-velocity, laminar, and ideal for high-speed drying, cooling and blow-off applications, including on large assembly production lines, such as auto bodies. Air Knives are also suitable for moving objects such as webs, film, sheets and strips.

Our Air Knives design is patented, producing highly efficient uniform air sheets, increased thrust and velocity, as well as reduced noise.
