Air Knife - Standard Air-Blade™

The Air Knife - Air-Blade Blow-Off System from Nex Flow™ is easy to install and maintain. It can reduce both compressed air consumption and noise levels.

It produces a “laminar” flow of air using the Coanda effect. This draws a large volume of air from the surrounding area along with the small amount of compressed air from the Air-Blade. It also produces an output flow up to 30 times.


The air knife system payback on compressed air savings can be seen in some applications.

Air Knife - Air-Blade Features:
  • The low cost air knives are rugged with a multiple port design for mounting flexibility. It is coated for longer life compared to competitive products that advertise a full flowing air knife type of system.

  • It is made of a coated aluminum body and hard-coated cap. Stainless steel models are available for high temperature and corrosive applications.
  • The multiple air inlet ports at the back ends in a compact design with additional mounting holes.
  • Airflow amplification is approximately 30:1 compared to 3:1 for drilled pipe or open jets and tubes.
  • There is instant on-off mechanism with no moving parts. There are no electricity or explosion hazards.

 Air Knife & Air-Blade Benefits:

  • It is built and designed for significantly longer life in difficult environments compared to competing products.
  • There are flexible mounting options and can easily fit in small spaces.
  • Energy reduction in compressed air can use up to 90% and noise reductions of 10 DBA.
  • It is maintenance-free. The output is easily controlled and safe to use.
