Description

 

Nex Flow Ring Blade produces a “laminar” flow of air along its 360º angle using the “Coanda” effect. Ring Blade entrains a large volume of air from the surrounding area along with the small amount of compressed air to produce an output flow up to 30 times the compressed air input. The blow-off is angled against the direction of flow of the part to shear off moisture and dirt effectively, even for irregular shaped parts.

Ring blades are available in 3 versions, made of differend materials: Anodized aluminium (up to 66°C), Anodized aluminium with stainless steel hose (up to 200°C) and Stainless steel 316L (up to 430°C).
