Air knives are widely used in the industrial field for blowing water and 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. Under the condition of compressed air supply, the air knife can perfectly satisfy these applications. The air knife can be driven by a vortex fan or a high-pressure centrifugal fan (instead of high-energy-consuming compressed air). It uses different fans to cooperate with the air knife to dry the dust and moisture on the surface of the object in time. According to different needs, wind knives with different functions are extended. Working principle: 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 accommodate 30 to 40 times the ambient air, forming a thin high-strength, large-flow impact air curtain.

There are two types: the air curtain of the standard air knife is deflected 90 degrees and blown out, and the air curtain of the super air knife blows out horizontally. Features: The air knife is made of aluminum alloy or stainless steel. The aluminum alloy air knife can be used in high temperature and highly corrosive environments; the "full airflow" design means that 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; the air knife can drain up to 40 times the ambient air, and the air consumption is only 1/5 of the traditional blow pipe; there are no wearing parts inside the air knife. The gasket is made of stainless steel and has a service life of more than 10 years. It is driven by compressed air, requires no electricity, and can be used in explosion-proof environments. The air knife produces a powerful air curtain, which can be used for various blowing and air cooling applications, such as: automotive industry: used to blow off extra water, coolant, dust, debris, etc. during production, and blow air cooling before steel plate painting , drying and dust removal. Electronics industry: Electronic circuit boards are quickly dried before assembly.

Beverage canning and bottling: Before labeling, inkjet or packaging of beverage bottles, the moisture and attachments from the mouth or body of the bottle should be blown away. Chemical industry: Blow off surface chemical substances or moisture before labeling or packaging. Food and medicine: Before making or packaging, blow off moisture and attachments, or remove dust from the opening and bag before filling. Metal industry: blowing coolant or other liquids from metal surfaces. Rolling mill emulsion blowing. The surface is dried or cooled before polishing, electroplating, and spray painting. Rubber and plastics industry: Blow off dust or debris on the product surface. Drying before ejaculation or ejaculation. After injection molding, the product cools. Printing (inkjet): Blow off dust, debris, and water vapor before inkjet and printing, or use it to quickly dry the ink.
