Vortec Aluminium Air Knife 921-12-BSP
The Vortec Aluminium Air Knife 921-12-BSP is an efficient air knife designed for blowing, cooling, and drying wider surfaces in industrial processes. This aluminium air knife is developed for applications requiring uniform and powerful airflow across a greater width compared to more compact air knife models.
With an overall length of 305 mm and a single air inlet, this model offers a versatile balance between compact design and coverage of wider surfaces. It is ideal for applications requiring consistent airflow across medium widths. Using Vortec’s patented technology, a controlled amount of filtered compressed air is amplified and converted into a high-velocity, laminar air blade with excellent uniformity and stable performance.
Application and Function
The Vortec Aluminium Air Knife 921-12-BSP functions as an air amplifier, efficiently converting compressed air into a stable and evenly distributed airflow along the entire length of the knife. The flat air blade ensures repeatable industrial results and makes this air knife particularly suitable for continuous processes involving moving materials.
The single air inlet design allows for simple installation and flexible integration into existing systems, while maintaining stable and uniform performance when supplied with compressed air. This model is well suited for applications where one air inlet is sufficient to ensure consistent airflow across the working width..
This air knife is commonly used for air knife blow off of water, dust, and process residues, as well as for drying or cooling workpieces where traditional blowers or open compressed air nozzles are inefficient, noisy, or energy-intensive. Manufactured in aluminium, the robust construction and simple design without moving parts ensure high operational reliability and minimal maintenance—even in demanding industrial environments.
Typical Applications
- Blowing and drying of wider industrial surfaces
- Air knife blow off of water and contaminants
- Drying prior to painting, coating, or printing
- Cooling or cleaning of sheets, strips, and moving workpieces
- Replacement of multiple nozzles with a single uniform air solution
