Application of high-pressure blower and air knife

Air knives have a large number of applications in the industrial field such as blowing water and blowing dust, such as blowing off dust and moisture on flat surfaces such as steel plates and aluminum alloy profiles, blowing off moisture on the surfaces of beverage bottles, packaging cans, etc., and blowing off products. Impurities and dust on the surface, residual liquid, moisture on the outer packaging, and conveyor belt cleaning, etc. Air knives are ideal for these applications when supplied with compressed air.

After the compressed air enters the air knife, it is blown out at high speed as an air flow sheet with a thickness of only 0.05 mm. Through the Coanda effect principle and the special geometric shape of the air knife, this thin air curtain can absorb up to 30 to 40 times the ambient air to form a thin, high-strength, large-flow impact air curtain. Air knives are divided into two types: standard air knives and super air knives in terms of working modes. The air curtain of the standard air knife is deflected 90 degrees and blown out, while the air curtain of the super air knife blows out horizontally.

Features of air knife：

1. The air knife is made of aluminum alloy or stainless steel. The aluminum alloy air knife has been electroplated in the manufacturing process, and its service life is much longer than other similar products. The stainless steel air knife can be used in high temperature and highly corrosive environments;

2. Full airflow design, that is, the width of the air knife is exactly the same as the width of the air curtain blown out by the air knife. There are installation and connection screw holes on the back of the air knife, and the required length can be combined as needed;

3. The air knife can drain up to 40 times the ambient air, and the air consumption is only 1/5 of the traditional air blowing pipe;

4. There are no wearing parts inside the air knife, and the internal gasket is made of stainless steel, with a service life of more than 10 years;

5. It is driven by compressed air, does not require electricity, and can be used in explosion-proof environments.
