I believe many friends can’t tell the difference between air knives and air knives. When these two products are compared, customers often say that they need to buy an air knife when they purchase an air knife. In terms of use, due to similar reasons in many aspects of use, many equipment manufacturers often call air knives air knives, and air knives are also called air knives. However, in practice, they have certain limitations. Different, but the specific application needs to be selected according to the user or actual application needs. Since you need to choose, you need to understand the specific differences between Hank air knives and air knives in order to better design and optimize the equipment. The difference between air knives and air knives mainly depends on the air source.

Air knife : The air source used is mainly compressed air. The general working pressure requirement is 4-8kg/cm2, so it is called air knife.

Air knife: The air sources used by air knife mainly include centrifugal fan, medium pressure fan, Hank high pressure blower, vortex fan, high pressure centrifugal fan, high speed turbine fan, Roots blower and other fans as the air source, so it is called air knife. The general working pressure requirement is relatively low, 2-50KPA is enough.

1. Structural characteristics

Air knife: The structural size is relatively large. Since a fan is used as the air source, the air inlet duct of the air knife and the air knife body are also relatively large. The main purpose is to reduce the air source pressure used. The opening width of the air knife is generally 0.3-5mm, and the air volume required is relatively large. The blade curtain of the air knife is also relatively wide, and the applicable occasions are relatively wide. It depends on the air source resolution.

Air knife: The structure size is small, because compressed air is used as the air source, the air inlet pipe used is relatively small, and the compressed air pressure is relatively high, so the outlet width of the air knife is relatively small, generally 0.03mm-0.1mm , so the required air volume is relatively small and the pressure is relatively high. In practice, it is a product developed based on the characteristics of compressed air. The device is relatively sensitive and the air curtain is relatively small. The equipment with high pressure can achieve better results. Direct ion air knife

2. Use of air knife: The air outlet has a certain temperature and the drying effect is relatively good. The cost of using the air source of the equipment is relatively low, but there will be fan noise on site. The most common application is the air knife.

Air knife: The air curtain is relatively small, the pressure is high, and the installation is relatively convenient. It can be installed on narrow equipment. The air outlet is cool wind, which is more suitable for relative cooling.

3. Installation Space Air Knife: The installation space requirements are relatively large. Generally, the size of the air knife is 130-200mm in height and 50-100mm in width. The specific requirements depend on the type of air knife and the inconsistent design of the manufacturer. The air intake duct of the equipment is also relatively large: the installation requirements are very small. The general size of the air knife is 45-60mm in height and 30-40mm in width. The air intake duct of the equipment is relatively small.
