The working principle and use of super air knife

Time:2022-12-16Clicks:100

High-intensity impact airflow is formed through the action of the air knife, which is used in cleaning, drying, cooling and other occasions. It has the characteristics of high efficiency, low noise and low air consumption.


How the super air knife works:


Compressed air passes through the air inlet


(1) Entering the high-pressure chamber of the air knife, the airflow passes through the narrow and thin nozzle;


(2) Finally, a balanced airflow sheet is formed in the length direction of the air knife. Due to the chamber;


(3) The compression ratio of the high-pressure air flow is 40:1, which makes the air flow speed loss the smallest and the pressure the largest, thus creating an air flow sheet with strong impact force and minimal shear force.


Traditional air blowing products have many disadvantages, such as: the blown air flow is uneven; the compressed air consumption is very large; although it has a weak impact force, the noise level is too high, seriously affecting the health of on-site operators; electric-powered products Inflatable products often require frequent maintenance and have short service life.


Super air knife


Super air knife features:


1. Low noise, only 69 decibels in most cases, which is about 10 times lower than conventional drilled pipe air curtains;


2 Save compressed air, and the air consumption is about 60% less than that of conventional drilled pipe air curtains;


3. The air flow is balanced and the air compression ratio can reach 40:1 ratio;


4. No moving parts, made of aluminum or stainless steel;


5. Small size, easy to install and free of maintenance;


6. Various specifications of air curtain width (100-1200mm) are provided, and the air flow intensity is adjustable (with pressure regulator);


7 The air knife can replace traditional fans and blow tubes.


Super air knife application:


1. Cooling and drying of parts after cleaning process;


2. After the beverage filling process, it is dried by high-pressure air and then labeled; 


3. Plate finishing in strip rolling mill;


4 The conveyor belt organizes the smoke exhaust area during engine testing; 


5. Water removal and drying of vegetables and fruits before packaging;


6 Fabric drying or cleaning;


7. Organize the working environment on the production line;


8 Pretreatment before electroplating or painting;


9 Coating machines in paper and printing industries;


10 The opening of the packaging bag when the packaging machinery is operating. Stainless steel air knife
