What is an Air knife?

Air Knife system is one of the most economical and cost-effective way to deliver a hard-hitting sheet of air over short or long distances. Compressed air is the only requirement for operation. There are no moving parts, electricity, or costly downtime. Air knives utilize the coanda effect (entrainment of surrounding air) to amplify the air upwards of 40 times, making them very efficient. Air knife systems utilize compressed air in many industrial applications such as drying, cleaning, wiping, cooling, and blow off.
