Product Details

RAETTS Spider Air Knife is developed from countless tests and practical experience. Its pioneering design concept not only improves the effect of the air knife drying system in the wine and beverage industry, but also greatly reduces the energy consumption of the system. When traditional air knives are used in wine and beverage filling production lines, the blowing force of the two air knives(which is against blow) will offset each other, resulting in a drying blind area. Due to the large volume of the traditional air knives, they are blocked by the guardrail during installation, cannot approach the bottle, and the angle cannot be adjusted. The invention of RAETTS Spider Wind Knife solves the above problems.
