Air Amplifier (venturi nozzle)<\/h2><\/div>

Our Air Amplifiers are quiet and at the same time very efficient. They amplify the air volume up to 25 times the compressed air consumption!<\/p>\n<\/div>

What are Air Amplifiers (Venturi Nozzles or Airflow Amplifiers)?<\/strong><\/h3><\/div>

Venturi nozzles are a simple and cost-effective<\/strong> way of transporting or moving air, smoke, gases and lightweight materials. In addition, these air amplifiers are an optimal solution for cooling large components or for drying workpieces.<\/p>\n

All Air Amplifiers use the Coanda effect<\/strong>, a basic fluidic operating principle. The air amplifiers have low compressed air consumption, but entrain a lot of ambient air. As a result, they create a large volume of air at high velocity when the air exits.<\/p>\n<\/div>

For example, our Adjustable Air Amplifiers are suitable for cooling and drying large metal parts<\/strong> in a foundry (as seen in the picture).<\/p>\n<\/div>

Why use air amplifiers (venturi tubes)?<\/h2>\n<\/div>

Air amplifiers have no moving parts and are maintenance free<\/strong>. An electrical connection is not needed.<\/p>\n

Additionally, the flow rate, vacuum and speed are easy to control. The flow rate at the air exit can be easily increased<\/strong> by enlarging the opening gap. Similarly, the flow rate at the air exit can be easily decreased by reducing the input pressure. The two sides, the air intake or air discharge end of the air amplifier can be connected using hoses; they are ideally suited to, e.g., taking in fresh air from a different zone, or from the ambient air, or extracting smoke and gases.<\/p>\n<\/div><\/div><\/div>
