Compressed Air Operated: Air Knife – Air Knives
STREAMTEK's Air Knives are the most efficient and energy saving method to deliver compressed air for large drying, cleaning or cooling applications.
The air knife operates by entraining the surrounding air along with the compressed air utilizing the "coanda" effect essentially converting the energy which would normally be lost as noise and pressure drop into a laminar (uniform) sheet of air that is projected along the entire length of the air knife to provide an air flow that covers the entire surface of the product.
The Regular Air Knife provides good performance with a 30:1 air amplification ratio that is less efficient that the Advanced Air Knife. Air consumption is ~3.4 SCFM per inch at 80 PSIG. The Regular Air Knife is a good choice when a less expensive alternative is required. As you can see, it is louder and uses more compressed air than the Advanced Air Knife.
The Advanced Air Knife provides the best performance with a 40:1 air amplification ratio, making it the most efficient. Air consumption is ~2.9 SCFM per inch at 80 PSIG. The Advanced Air Knife is normally the best choice due to very low noise levels and using less air than the Regular Air Knife at same pressure.
