Aluminum Air Knives

Lightweight and Efficient

Aluminum air knives are usually more economical, lighter and available in longer sizes. These are mostly used in the construction and non-food industries.

DOVAC air knives, or air knives, generate a laminar airflow ideal for drying, cooling, or cleaning various products and parts. This airflow also attracts ambient air, increasing its effectiveness, as seen when drying cars in car washes.

Aluminum air knives are available from a width of 100mm to 3000mm. Their advantages include precise air control, ability to handle high temperature and pressure differences, and customizable slot widths for different applications.

The lightweight properties of DOVAC's aluminum air knives make them highly suitable for applications where the air knives must be moved frequently or where the structure supporting them cannot support much weight. This makes them ideal for mobile systems or for installations in areas with limited construction options. In addition, the lightweight aluminum makes installation and maintenance easier and less time-consuming, which also reduces installation costs. The durability of the material ensures a long service life even under harsh operating conditions, making them a cost-effective long-term choice.

In addition, DOVAC's aluminum air knives offer excellent thermal and acoustic insulation due to their design and choice of materials. This not only reduces noise levels during operation, contributing to a more pleasant working environment, but also helps improve energy efficiency by minimizing heat loss. These properties make aluminum air knives particularly effective in situations where temperature control is critical, such as in drying processes where consistency and precision of airflow are essential to the quality of the final product.

We offer our DOVAC air knives in a variety of designs specifically tailored to the application. The size of the area to be dried dictates the required length of the air knife, along with the required power of the blower.

Air knives are designed for fixed mounting and permanent use and should be mounted to allow adjustment for optimal results with different products. The positioning of the air knives in relation to the product is extremely important for effective drying, - and cleaning. Take special care when air knives are moved/adjusted due to different product sizes. In general, the closer the air knives are mounted to the product to be cleaned, the greater the effectiveness of the blowing process.

Lightweight solution for powerful airflow

Aluminum air knives are an efficient and cost-effective solution for creating a powerful, even airflow over a wide area. They are widely used in applications where weight and price are a consideration, but performance must not be compromised.

Our air knives are designed for a wide range of industrial applications, including:

• Blowing off liquids, dust or chips
• Cooling of products or surfaces
• Drying after cleaning or rinsing processes
• Airgordijn systems for separation or protection

The optimized design creates even air distribution along the entire length, with high blowing power and low noise production. Combined with our energy-efficient side channel blowers, the aluminum air blades are a sustainable alternative to traditional compressed air solutions.

Typical applications

DOVAC's aluminum air knives are used in such applications as:

• Packaging lines (drying of film or boxes)
• Spray booths (dust or vapor extraction)
• Production of profiles or extrusion (cooling)
• Food industry (blowing off water droplets)
