Product Overview

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.

Applications

  • Drying after wash, cleaning, plating or coating
  • Blow off dust and contaminants
  • Cool hot extruded shapes
  • Uniformly wipe surfaces
  • Dry extruded profiles, rod and medical tubing
  • Blow excess water from automotive door gaskets
  • Remove excess coatings, water and oil
  • Dry tube, hose, wire, fiber optics
  • Clean paint gun tips

How The Nex Flow® Ring-Blade® Air Blow-Off System Works

Compressed air enters at point (A) into an annular chamber and throttled through a small ring nozzle at high velocity. This air stream clings to the Coanda profile directing the air stream down toward the surface which is angled to create a “cone” style directed force to best clean, wipe and dry a surface. The surrounding air is entrained at point (B) creating an amplified 360-degree conical airflow at point (C) to uniformly wipe the surface of the of the material running through the Ring Blade®. The wet or dirty material (D) direction of travel is against the flow.
