Vortec Aluminium Air Knife 921-18-BSP
The Vortec Aluminium Air Knife 921-18-BSP is a high-performance air knife designed for blowing, cooling, and drying wide surfaces in industrial processes. With an overall length of 457 mm, this model is ideal for applications requiring uniform and powerful airflow across larger widths. Equipped with two air inlets, the air knife ensures optimal air distribution and reduced pressure loss, delivering consistent performance across the entire length—even in demanding production environments.
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 921-18-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 dual air inlet design enhances airflow uniformity and ensures consistent results across wider surfaces.
The flat air blade ensures repeatable industrial results and makes this air knife particularly suitable for continuous processes involving moving materials. 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 wide 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
