Air Wipes

The Nex Flow™’s Ring Blade™ Air Wipe is a lightweight, compact, and easy to install, piece of equipment that  produces an even 360 degree blow off around the part. It reduces compressed air use for energy saving as well as significantly lowers noise levels. The systems are essentially maintenance free with blow off output easily controlled with a regulator.

Air wipes are basically air knives arranged in an annular form – like Air Amplifiers – but split into two half circles and then joined together.   These units are used as efficient blow-off system for all types of extrusions – wire, cable rope, window profiles, automotive trip, extruded pipe, and other applications. Nex Flow^™ produces sizes from 3/8” diameter to 11” diameter as a standard and have produced special sizes when necessary.

They are designed as two separate pieces hinged together to open and close around the extruded or moving 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 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.

Available in 10 standard (inside) diameters AND in 3 Versions

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 and force. Materials of construction are anodized aluminum or 316L stainless steel.
