Ring Blade™ Air Wipe Blowoff Systems

Clean & Dry Any Extrusion


The Nex Flow™’s Ring Blade TM Air Wipe produces an even 360 degree blow off around the part, light in weight and compact. Easy to install and maintain and allows removal of a continuous piece. Reduces compressed air use for energy savings plus lower noise levels. Maintenance free with output easily controlled.

Designed as two pieces hinged together to open and close around the part. Instant on-off with no moving parts The 360 Degree Air Wipe System produces a “laminar” flow of air along its 360º angle using the “Coanda” effect which “entrains” a large volume of air from the surrounding area along with the small amount of compressed air from the Air Wipe System to produce an output flow up to 30 times


Special diameters for the Air Wipe Blow-Off System are available on special request from Nex Flow™.

Each Ring Blade™ comes with a standard .002″ outlet gap which will work for 90% of all applications encountered.

If greater force is required, a second .002″ (.05mm) shim may be installed to open the gap for greater flow. Materials of construction anodized aluminum or 316L stainless steel.
