Air compressed circular air knife for drying and blowing

Circular air knife/air knife:

Features: low noise, low air consumption, no moving parts, maintenance-free, powerful blowing force, efficient water and dust removal.

Application: Widely used in cable and wire, steel pipe, automobile manufacturing, metallurgy, extrusion products, steel, plastic hose and other industries for rapid cooling, dust removal, drying, cleaning, etc.

Material: Aluminum Alloy & Stainless Steel (Special materials can be customized)

The company develops, produces and sells various types of circular air knives/air knives. The standard size models are shown in the table below. If there are special specifications and sizes, they can be customized according to customer needs. We will provide customers with free designs. Please feel free to contact us.

Working principle diagram of annular air knife:

When compressed air enters the high-pressure chamber (2) of the annular air knife through the air inlet (1), the air flow is sprayed out along the side wall (4) of the annular air knife at an ultra-high speed through the small nozzle (3). A powerful vacuum zone (5) is generated in the back. The high-speed jet of air pulls a large amount of air around the air knife and jets it to the other side of the air knife, thereby generating a powerful 360-degree sweeping force. This uniform and powerful air flow The oily dirt, water and other impurities on the material (6) passing through the air ring can be blown continuously and stably.

The magnification of RAW airflow is 40:1, and the high-flow airflow it produces can provide cooling and drying on all sides of the product. The 360-degree circular structure can produce a stable, powerful airflow wrapped around the side of the object, so that all water and oil can be removed. Used for drying, dust removal, oil removal, water removal and liquid removal, etc.

Features of circular air knife:

1) Balanced air flow, super blowing force, air compression ratio up to 40:1 ratio
2) Very low input and operating costs, which can save 35-50% of compressed air costs
3) No moving parts, long service life. Can work in high and low temperature environments
4) Low noise, in most cases only 65 decibels, the noise is about 25% lower than that of a straight blown pipe
5) It has small size, easy installation and maintenance-free
6) No electricity, no electromagnetic radiation, no explosion hazard, safe and reliable

Environmental application of ring air knife:

- Drying is required after washing, cleaning, plating or coating
- Cooled and extruded parts
- Blow off oil, debris, waste, water and dust on the tubular surface
- Cooling molds or castings
- Cool continuous length parts such as metal wires, wires, hoses, pipes, etc.
- In the process of removing the material in the radial conveying process, the dirt passes through to provide an ideal drying solution for pipes, cables, extruded materials, wires, rulers and water pipes.
