DOVAC Stainless Steel Air Knives

Powerful and Sustainable Technology

Stainless steel air knives are often used in the food and chemical industries.
The advantage of stainless steel air knives is that they are resistant to acids and aggressive cleaning agents.

DOVAC air knives or air knives produce a laminar airflow and are perfect for drying, cooling or cleaning a variety of products and parts.
This airflow also draws ambient air with it, further increasing the effectiveness of the airknives.
A recognizable example is blowing cars dry at the car wash.

Stainless steel air knives are available in widths from 300mm to 2500mm.
The advantages of our air knives are high accuracy, high temperature differences, large pressure differences and adjustable slot widths.

DOVAC’s stainless steel air knives offer excellent corrosion resistance, making them particularly valuable in environments where hygiene and cleanliness are essential, such as in the food processing and pharmaceutical industries. Their ability to withstand high temperatures and aggressive chemicals allows regular and intensive cleaning without the risk of degradation. This is crucial for companies that meet strict sanitation standards and depend on reliable equipment that does not compromise the quality of their products.

In addition, DOVAC’s stainless steel air knives are designed for efficient operation, not only maximizing airflow but also minimizing energy costs. Because of their ability to attract and amplify ambient air, these air knives deliver a powerful, even airflow that provides rapid drying or cooling. This increases production speed without additional energy consumption, making them a cost-effective solution for a wide range of industrial applications. Their adaptability in terms of slot width and airflow control also allows users to fine-tune the air knives to specific process requirements, enabling further optimization of the production process.

We supply our DOVAC air blades in different versions, tailored to the specific application.
The size of the surface to be blown off determines the required length of the air knife, combined with the power a blower must provide.
