What is an Air Curtain?

This is a device that produces high-velocity air stream(s) that help execute various operations. It is primarily used in cooling, drying, blow-off, or light conveying applications. It can effectively be integrated into almost any manufacturing or processing line.

Streamtek is reputed for its compressed air-powered Air Curtains that functions on the coanda effect for enhanced performance. Air Knives based on the coanda effect produce balanced airflow that stretches across the full length of the air curtain. Streamtek offers Air Knives in aluminum and stainless steel.

What is the significance of an air curtain?

There are a myriad of commercial and industrial applications that benefit from the use of an Air Curtain. It can be used in various environments where applications such as blow-off, cooling, drying, dust containment, part cleaning and air-based conveying are required. Such devices can even be specially manufactured for use in clean rooms.

An Air Curtain is more energy-efficient and saves more compressed air than conventionally-used air blower fans. Streamtek has hundreds of customers that have successfully switched in their industrial environments from their old drilled pipe setup to Air Knives with positive results.

How Does an Air Curtain Work?

Streamtek Air Curtains utilize the coanda effect (wall attachment of high velocity fluid) so as to create a steady, invisible barrier of high velocity air. Thus, air motion is created around the Air Knife and ambient air is drawn in to produce a high velocity air stream. This makes our compressed air-powered Air Knives exceptionally energy-efficient air blower.
