Description
EXAIR · Super Air Knife EXAIR
What is the EXAIR Super Air Knife?
The EXAIR Super Air Knife is a highly efficient industrial air curtain designed to reduce compressed air consumption while delivering powerful and uniform airflow for blowoff, drying, cooling, and cleaning applications.
Even at operating pressures of 80 PSIG (5.5 BAR), noise remains at just 69 dBA — a mere whisper compared to traditional blowoff solutions like drilled pipes and open tubes.
How EXAIR Super Air Knife Works
Compressed air enters an internal chamber and exits through a thin precision slot creating a laminar air curtain. Ambient air is entrained at a 40:1 ratio, dramatically increasing blowoff performance while minimizing compressed air consumption.
By amplifying ambient air instead of relying solely on compressed air, the system reduces compressor load and lowers operating expenses while maintaining consistent airflow performance.
Industrial Applications
Energy efficient air knife EXAIR technology is used in manufacturing, food processing, packaging, automotive, metalworking, and plastics industries.
Ideal for removing water, oil, dust, debris, chips, and contaminants from products and surfaces during production processes.
Installation & Design
The EXAIR Super Air Knife is available in aluminum and stainless steel models. Its compact design and dual air inlets simplify installation in tight production areas while allowing flexible airflow adjustment according to process requirements.
Unlike conventional blowers or fans, the system contains no moving parts, eliminating maintenance requirements and improving long-term reliability.
Applications
Drying of parts after washing.
Cleaning of blades.
Cleaning of conveyors.
Cooling of parts or components.

How to Clean the Exair Air Knife.
How does the Exair air knife work?
Compressed air enters through an inlet (1️⃣) into a chamber inside the Super Air Knife. The flow is directed toward a precision slotted orifice. The main airflow exits the thin slot of the nozzle (2️⃣), which follows a surface that directs the airflow in a perfect straight line. This creates a uniform sheet of air along the length of the Super Air Knife. Speed loss is minimized and force is optimized, with ambient air (3️⃣) being pulled into the primary airflow at a 40:1 amplification ratio. The result is a well-defined laminar airflow sheet with strong blowing force that’s unaffected by wind.
