Application Cases of Air Knife with Side Channel Blower

What is an Air Knife?

An Air Knife is a commonly used drying accessory in industrial equipment and production lines. It generates a high-velocity, uniform airflow that efficiently removes moisture, dust, and debris from surfaces. Air Knives are extensively applied in drying, cooling, cleaning, and air separation processes across various industries.

Types of Air Knives

Air Knives can be classified based on their design and material composition:

• Coanda Effect Adjustable Air Knife: Utilizes the Coanda effect to direct airflow efficiently. The airflow volume and angle can be adjusted to suit different industrial needs.

• Standard Air Knife: Delivers a consistent and high-velocity air stream without requiring significant adjustments.

• Material-Based Classification: Air Knives are available in materials such as aluminum, stainless steel, and plastic, each offering unique advantages depending on the working environment.

The selection of an Air Knife often determines the specifications of the Side Channel Blower used in the system, ensuring optimized performance for different applications.

Applications of Air Knives

Food Production Line

In the food industry, maintaining hygiene and product quality is critical. Air Knives paired with Side Channel Blowers play a vital role in:

• Drying packaged food products before labeling to ensure adhesive efficiency
