Air Knife X-Stream™ Standard

X-Stream™Air-Blade™ Air Knife Curtain Blow-Off System from Nex Flow™

Air Knife, X-Stream, Curtain Blow-Off System, Nex Flow X-Stream™ Air-Blade™ Air Knife is easy to mount and maintain and reduces both compressed air consumption and noise levels. It is the most efficient design yet achieved for air knife curtain blow-off technology for reducing noise levels yet providing the optimum in blow-off energy.

X-Stream™ Air-Blade™ Air Knife produces a “laminar” flow of air along its length using the ”Coanda” effect which “entrains” a large volume of air from the surrounding area along with the small amount of compressed air from the X-Stream™ Air-Blade™ Air Knife to produce an output flow up to 40 times.

System payback on compressed air savings can be as soon as a few weeks in some applications.

Silent X-Stream™ Air Blade™ Air Knife

Compressed air enters the air knife at the rear (or end) ports at (A). Air is entrained at point (B) and (D) by the compressed air stream that leaves the air knife from a small gap at point (C). The entrained air follows the profile that directs the airflow in a perfect straight line to create a uniform sheet of air along the entire length of the Air Blade™ air knife. The amplified air stream maximized velocity and force is maximized as a well-defined sheet of laminar flow with minimal wind shear for reduced energy use in blow off and cooling.


How It Works

Air Knife, X-Stream, Curtain Blow-Off System, Nex Flow

X-Stream™ Air-Blade™ Air Knife produces a curtain of air along the length of the application using the same "Coanda" effect utilized in our Air Amplifiers. There are no moving parts, with compressed air from a local production line source being used to amplify end entrain surrounding air. Output volumes almost twenty times higher than those at the input can be achieved.

Offered in aluminum or stainless steel and can be manufactured in any length from a combination of our standard sizes.


X-Stream™ Air-Blade™ Air Knife is a full flow design with rear port mounting to avoid interference with entrained air flow, optimizing air amplification, and minimizing noise levels. It is gold coated for longer life.

  • Made of aluminum and coated for long life. Stainless steel models are available for high temperature and corrosive applications.
  • Built and designed for significantly longer life in difficult environments than many competing products.

  • Air inlet ports on the back for a compact design and minimal air interference.
  • Easy to fit in small spaces.

  • Airflow amplification of approximately 40:1 compared to 3:1 for drilled pipe or open jets and tubes.
  • Energy reduction in compressed air use up to 90% and noise reductions of 15 dbA.

  • Instant on-off with no moving parts, no electricity or explosion hazard.
  • Maintenance free with output easily controlled, safe to use.

Air Knife, X-Stream, Curtain Blow-Off System, Nex FlowApplications

Typical applications replace drilled pipe, or rows of nozzles used for blow-off, cleaning, drying or cooling.

  • Automotive
    Remove water, coolant, dust, and scrap in parts manufacturing and in assembly operations. Can be used to cool parts.
  • Bottling
    Blow off of water prior to labeling, palletizing or packaging. Moving light materials. Open and close packaging lids or tops.
  • Chemicals
    Blow off of chemicals or water prior to labeling or packaging as with bottling operations.
  • Food
    Remove water from product or packaging. Control application of some materials to the food product such as sugar, icing etc. Open pouches in bagging operations. Dry food.
  • General Manufacturing
    Part ejection, air curtain barrier, dust and liquid blow off from all types of parts. Ideal for replacing fans in some cooling operations.
  • Metals
    Coolant and other liquid removal on process lines from Aluminum, Steel, Brass or other materials. Dry metals prior to other operations such as plating or polishing. Cool metal parts prior to coating or painting.
  • Paper & Lumber
    Paper dust removal and control. Dust removal from plywood and panel board.
  • Plastic
    Dust and scrap blow off. Cool off molten plastic in dip molding.
  • Printing
    Cooling to set some inks, scrap blow off, hold down labels prior to printing, cool adhesives to allow faster speeds in label applications and binding operations.
  • Pharmaceutical
    Remove liquid prior to labeling or packaging waste removal from solid materials.
  • Textile
    Cleaning and drying of cloth or other materials.
