Air Curtains

An air knife or curtain offers an efficient way to clean, dry or cool parts, webs and conveyors.

Arizona Vortex air curtains reduce the amount of compressed air used and put out more air than older conventional models. Air curtains are used for large area blow off and cleaning of flat surfaces. They can amplify air flow up to 40 times the air input volume.

They are available in standard lengths of 6″, 12″, 18″, 24″, 30″ and 36″, and offered in aluminium or stainless steel. Stainless steel air curtains are ideal for applications in corrosive or hazardous areas.

How do vortex air curtains work?

Vortex air knives force a small amount of compressed air through an orifice or slot along the length of the air curtain, which causes the air to move at sonic speed. The sonic speed of the compressed air creates a low pressure area along the air foil of the body causing the surrounding air to create large flows of air. Since the Vortex Air Curtains use less compressed air the noise levels are almost eliminated.



Cleaning of flat surfaces, creating air curtain separation, cooling of hot parts or extrusions, cleaning of conveyers, removing water from parts.
