What is an air knife system?

Air Knife Systems use Air Knives that have precision-engineered linear slots to direct and utilise high-velocity air generated by a centrifugal blower. Air Knife Systems are highly effective at cleaning, drying, blow-off and liquid control for a wide range of applications.

What are air knives used for?

Air knives are primarily used on conveyor belts in manufacturing applications for drying products or to remove unwanted objects. Air knives use a plenum chamber to distribute pressurised air across a wider area. The housing is usually a strip of metal containing holes which produces an even distribution of the compressed air.

How do air knives work?

Air Knives are often the most energy-efficient and effective method of removing or controlling foreign substances for any surface. Most Air Knives are stationary with products passing through them on a conveyor however there are also systems where the product is stationery and the Air Knives move around it.

How many air knives can be used in an air knife system?

The Air Knives used in an Air Knife System usually range from 100 to 3048 mm (4 to 120 inches) in length with a discharge air slot ranging from 0.40 to 2.0mm (0.015 to 0.08 inches). A stationary air knife configuration can require from one to ten or more air knives, depending on the application criteria.

How long is an air knife?

There are different lengths of air knife available, from 80mm to 900mm. So you will be sure to find an air knife system suitable for your application. The airknife housing is usually made from stainless steel or lightweight aluminium. Air knives can perform a variety of tasks using a flow of pressurised air.

What is an industrial air knife?

An industrial Air Knife is a pressurized air plenum chamber with a continuous slot through which pressurised air exits in a laminar (uniform) flow pattern. The exit air velocity creates an impact air velocity onto the surface of products that the air is directed toward. Read how air knives work
