How the Super Air Knife™ Works

Compressed air flows through the inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise, slotted orifice. 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.

 

How the Standard & Full-Flow Air Knife™ Works

Compressed air flows through the inlet (1) into the 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" (152 mm) away.

Universal Air Knife Mounting System

The Universal Air Knife Mounting System is used to provide secure, precise positioning for any of our air knives. The air knife can quickly and easily be moved within close proximity of the part to improve the effectiveness. It can be mounted on either the top or bottom of most air knives. The Universal Air Knife Mounting System has a durable, stainless steel construction that is suitable for a variety of industrial applications.
