The current air knife design has evolved into a company that produces a highly effective “teardrop” form with an emission factor of 0.95. The blower-driven air knife design is about 3.5 inches (89 mm) wide by 5.5 inches (140 mm) in any length, but to meet the impact of a 1.5 inch wind speed. The building’s thickness is from 1/8-inch (3.2 mm) aluminum to 11 stainless steels, and the weight of the air knife is 1 lb – 25 lb / ft. Depending on the width and speed of the product, the air knife provides an effective flashy performance of 0.5 to 12 inches above the product surface. A 25 “to 102” circular nozzle designed for this type of application is effective for multiple-foot surfaces from the surface of the product.
Current Air Knive Design
There are always different types of explosive devices. For high-pressure air knifes with a hollow tube design, wind blowing and compressed air nozzles are different. To use compressed air for maximum efficiency, many manufacturers use compressed air knifes to improve the design of compressed air knifes compared to other types of knives and nozzles. Low-pressure air has a much lower air efficiency than a blower, but Coanda air knife is breathing ambient air into high-speed airflows to improve ventilation.
The torn air knifes have a spherical knife that is operated with a blower by pneumatic industry standards and is reduced to the proper exhaust slot. The circular pipe with hole has an average emission factor of 60% efficiency, but the air knife in the form of teardrop usually gives higher surface air velocity at 95% efficiency. Air is caused by the lowest blower motor power demand. The teardrop design is offered not only in the form of extruded aluminum but also in the processing of carbon steel and stainless steel.
