Standard Air Knife

The EXAIR Standard Air Knife is a versatile tool designed for a variety of applications, such as drying parts after washing, cleaning conveyor belts, cooling components, and removing debris. Made from aluminum and Type 303 stainless steel, it offers lengths ranging from 3" to 48" with custom sizes available. Featuring a Coanda profile, it efficiently turns airflow 90 degrees, creating a low-pressure area that entrains ambient air at a 30:1 ratio. With minimal air consumption, uniform airflow, variable force and flow, and no moving parts, it meets OSHA requirements for pressure and noise, making it a reliable and maintenance-free solution.

How The Standard Air Knife Works ?

Compressed air flows through the inlet (1) into a plenum chamber. It is then throttled through a thin nozzle (2) extending the length of the Standard Air Knife. This primary airstream adheres to the Coanda profile (3), which turns it 90° and directs the flow down the face of the unit. The primary stream immediately begins to entrain surrounding air (4), for an amplification ratio of 30:1 at 6" (152mm) away.

Aluminum - The aluminum Standard Air Knife is suited to a wide variety of environments where corrosion or contamination is not a factor. The aircraft grade aluminum construction with plastic shim is very durable for general purpose applications. Stainless steel screws are used to eliminate corrosion in damp locations. It can withstand temperatures up to 180°F (82°C).

Type 303 Stainless Steel - This is the most common grade of stainless steel. It offers good strength and is best suited to mildly corrosive environments. It can withstand temperatures up to 800°F (427°C).

12" (305mm) Standard Air Knife tested with .002" (0.05mm) thick shim installed.

The Standard Air Knife is available in ten standard lengths of 3", 6", 9", 12", 18", 24", 30", 36", 42" and 48" (76, 152, 229, 305, 457, 610, 762, 914, 1067 and 1219mm). This measurement refers to the airflow length. The overall length is 1" (25mm) longer. Special lengths up to 48" (1219mm) are available. Any number of Standard Air Knives may be installed across a given area.

Compressed Air Inlets: A Standard Air Knife has compressed air inlets on each end. Lengths 24" (610mm) and longer should be supplied with compressed air at each end to maintain uniform airflow.

Filtration: The use of clean air is essential. Kits include an automatic drain filter with a 5 micron filter element that is sized properly for flow.

Materials of Construction: The Standard Air Knife is available in either aluminum or stainless steel construction.

Mounting: Universal Air Knife Mounting System. The Standard Air Knife can also be supported by the compressed air pipe.

Regulation: A pressure regulator on the compressed air supply provides infinite control of flow, force, and air consumption. Kits include a pressure regulator that is sized properly for flow.

Shim Sets: A Standard Air Knife has a .002" (0.05mm) gap setting. This gap is set with a shim positioned between the cap and body of the Standard Air Knife. Force and flow through the Standard Air Knife may be easily increased by adding shims to open the gap. Standard Air Knife Kits include a shim set (three additional shims). Shim sets for aluminum Standard Air Knives include a .001" (0.03mm) Amber color , .003" (0.08mm) Green color , and .004" (0.10mm) thick Tan color plastic shims. Shim sets for stainless steel Standard Air Knives include
