Vortex Air Curtains
Vortex Air Curtain replaces drilled pipe passing the air by drilling holes in a pipe and flat air nozzle, etc.. It provides energy saving effect for the investment, using a small amount of compressed air in the worksite. It is effective in drying, cooling and cleaning the products with large operation areas or the products being conveyed into the conveyor line.
Vortex Air Curtain is a device to jet high speed and high pressure air at a constant flow rate by drawing a small amount of compressed air and ambient air and causing the air to pass through an orifice at a sonic speed at the air amplification ratio of 25:1, using Coanda effect (the tendency of fluid to become attached to the surface of a curved body).
As Vortex Air Curtains use about 1/3 of air, the noise is within 70dBAat 7bar for all models, which is almost eliminated.

Flat Air Nozzle
 |
The materials of this product include two types of aluminum and stainless steel. Although the investment cost is low, it uses excessive compressed air (airconsumption 7,650ℓm at 4bar), which greatly exceeds OSHA standards. The wind speed and air volume of the product process flow are not constant, and it does notmeet the overall requirements such as moisture removal and drying. |

Blower
 |
It needs a high investment cost and a large space for installation. Although its operating cost is similar to that of Vortex Air Curtains of Seyang Mechatronics, the noise is 90dBA and ON/OFF cycle control for energy saving is not possible, and it needs a high maintenance cost due to costs of consumables such as regular bearings and filters replacement. |
Vortex Air Curtain

Vortex Air Curtains have assorted lengths. From small 3″75mm(aluminum) to the maximum size 36”900mm (aluminum, stainless steel), they generate uniformcurtain of air with the same wind speed and wind pressure. Vortex Air Curtains are excellent in performance, energy saving, noise reduction and stability. ※(70dBA) |

Uses
VVortex Air Curtains are available in standard lengths of 6”, 12”, 18”, 24”, 30”and 36”. Materials available are aluminum and stainless steel. The stainless steel units are ideal for applications in corrosive areas or hygiene areas such as food line or pharmaceutical factory line.
Electronic components and PCB drying process, automobile parts processing, auto cleaning dry line, surface cleaning, rapid cooling of plastic injection and extrusion operation.
Cooling drinks or hot products, dry cooling for the products transferred by a conveyor, painting line cleaning, removal of moisture after washing products, andsaving of compressed air consumption by 50%.
Features and Benefits
Vortex Air Curtains have assorted lengths. From small 3″75mm(aluminum) to the maximum size 36”900mm (aluminum, stainless steel), they generate uniform curtain of air with the same wind speed and wind pressure. Vortex Air Curtains are excellent in performance, energy saving, noise reduction and stability.
No additional parts are required, and instant ON/OFF control is possible. As an explosion-proof structure, it is very safe. It injects a small amount of compressed air to a large amount of air, by which it creates a flow increase effect required in the drying and cooling line. It can be also installed at a low cost.
