Super Air Knife

The EXAIR Super Air Knife is a highly efficient compressed air knife designed for blowoff, cleaning, drying, and cooling applications. It delivers a uniform sheet of laminar airflow across its entire length, providing powerful and consistent performance. The Super Air Knife is engineered to reduce compressed air usage and noise levels significantly, with an air amplification ratio of 40:1. Available in various materials, including aluminum, stainless steel, and PVDF, it meets diverse application needs. The Super Air Knife is also available in lengths up to 108 inches and can be equipped with plumbing kits, filter separators, and pressure regulators for enhanced functionality2.

How The Super Air Knife Works ?

Compressed air flows through an inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise, slotted orifi ce. As the primary airflow exits the thin slotted nozzle (2), it follows a flat surface that directs the airflow in a perfectly straight line. This creates a uniform sheet of air across the entire length of the Super Air Knife. Velocity loss is minimized and force is maximized as the room air (3) is entrained into the primary airstream at a ratio of 40:1. The result is a well defined sheet of laminar airflow with hard-hitting force and minimal wind shear.

Aluminum - The aluminum Super 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).

Type 316 Stainless Steel - Some applications require better corrosion resistance than offered by Type 303 stainless steel. Type 316 stainless steel offers excellent corrosion resistance, better strength properties and resists pitting. These factors are important to manufacturers of food, pharmaceutical and surgical products that need to minimize contamination by the metal. It can withstand temperatures up to 800°F (427°C).

PVDF (Polyvinylidene Flouridine) - EXAIR’s Super Air Knife is also available from stock in PVDF. PVDF offers superior strength and is resistant to UV light, inorganic chemicals, solvents, ozone, weather, fungi, chlorinated hydrocarbons, highly corrosive acids, weak bases and salts. The PVDF Super Air Knife uses PTFE shims, Type 316 Stainless Steel pipe plugs, and Hastelloy® C-276 alloy screws to withstand harsh environments. The PVDF Super Air Knife is suitable for manufacturing processes that involve electroplating, solar cells, lithium ion batteries, transfer of acids and caustic chemicals, brine, solvent recovery, semiconductors and medical devices. It can withstand temperatures up to 275°F (135°C).

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

The Super Air Knife is available in standard lengths of 3", 6", 9" 12", 18", 24", 30", 36", 42", 48", 54", 60", 72", 84", 96" and 108". Special lengths and unlimited system lengths are available. Any number of Super Air Knives may be installed across a given area.

Compressed Air Inlets: A Super Air Knife has compressed air inlets on each end and the bottom. Knives 24"-47" should use the 2 inlets at opposite ends of the knife. Knives 48"-59" use 2 inlets at opposite ends plus 1 near the middle on the bottom of the knife. Knives 60"-83" use 2 inlets at opposite ends plus 2 inlets equally spaced on the bottom of the knife. Knives 84" and longer use 2 inlets at opposite ends plus 3 inlets equally spaced on the bottom of the knife.

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 Super Air Knife is available from stock in aluminum, Type 303 stainless steel, Type 316 stainless steel and PVDF.

Other materials are available on special order.

Mounting: The Universal Air Knife Mounting System is available.The Super Air Knife can be supported by the compressed air pipe. Tapped holes (1/4-20) on the bottom are also provided.

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: The compressed air exhausts through a gap which is set with a shim. Force and flow may be increased by adding shims. Shim sets for aluminum Super Air Knives include a .001" (0.03mm) Amber color , .003" (0.08mm), Green color , and .004" (0.10mm) thick Tan color plastic shims. A Red color .002" (0.05mm) thick shim comes installed in the Super Air Knife. Shim sets for stainless steel Super Air Knives include (3) .002" (0.05mm) stainless steel shims. PVDF Super Air Knife shim sets include (3) .002" (0.05mm) PTFE shims.
