Engineering: Conventional air-knife vs new ILN concept air knife
High efficiency ILN air knife saves electric cost and provides higher thrust compared to standard air knives
High efficiency ILN air knife combined with engineered blower systems provides the lowest possible operation cost
Engineering graphs for design of Air Thrust, Air Pressure, and Air Consumption in air knife systems
Air-HyThrust has developed the ILN air knife nozzle concept designed to increase the mass-flow performance of a conventional air knife. The conventional air knife and the new ILN design were tested on the same Frame 75 turbo-blower at Phelps Fan, Little Rock AR in December 2016.
There is a 7% increase in mass flow performance and a 15% increase in thrust performance for the ILN air knife nozzle at a constant blower amp level.
Advantages of centrifugal air knife blowers vs. compressed air based systems:
Compressed air can be EXTREMELY INEFFICIENT and VERY POWER HUNGRY for air drying applications. Generating the necessary AIR COLUMN THRUST for most air knife applications with a compressor air system can consume over 400% of the electrical energy of a centrifugal blower based system.
Consider a compressor air system drying a 90” wide chain conveyor in continuous duty: this system will cost over $50,000 per year to operate based on electrical energy consumption. However, an AirBTU-Air Knife System with a high efficiency centrifugal blower will consume less than $7,000 per year to operate with the same functionality.
Our AirBTU-Air Knife Systems are precision-engineered and optimized to operate more efficiently, deliver higher air velocity, and produce better results than compressed air based systems.
Our AirBTU-Air Knife Systems are used in a wide range of processes for air drying and air blow off applications. Our high-efficiency centrifugal blowers produce the precise combination of air flowr and pressure required to shear water from surfaces ... removing machining chips, process oils, and other debris OR to smooth coatings and galvanizing applications OR to cool materials.
