Air Knives

ITW Vortec Curtain Transvector® Air Knives efficiently blowoff wide surfaces of debris as well as provide high speed drying or cooling for a broad range of industrial applications. Ionizing Curtain Transvectors® add a Static Neutralizing Bar to kill static cling and discharge dust and particles for blowoff.

Since Curtain Transvectors® are air amplifiers, they use a small amount of compressed air to deliver a powerful, high velocity, laminar sheet of air over wide areas such as moving webs, film, sheets, strips, auto bodies and other large assemblies and objects. Our patented design produces increased thrust and velocity, reduced noise, excellent uniformity, and significantly outperforms any competing, wide blowoff device. Stainless steel models are ideal for food, pharmaceutical, chemical and other applications where purity, high temperatures or corrosive environments are concerned.

Features
  • More compact and affordable than electric blowers
  • High performance patented design
  • No guards or rotating machinery
  • Instant on/off – output air easily regulated
  • Compact and easily mounted
  • No moving parts – maintenance-free
  • Quiet – Meets OSHA noise specifications

Curtain Transvectors®, as well as the Ionizing versions, have numerous and diverse processing, finishing, fabrication, assembly, and other industrial uses for cooling, drying, cleaning or static removal on wide surfaces, including:

  • Food processing
  • Shrink wrapping
  • Clean room procedures
  • Form and fill
  • Films and plastics
  • Textiles
  • Printing and labeling
  • Converting and packaging
  • Woodworking and laminates
  • Paint preparation and drying
  • Sheet and web materials
  • Conveying or hold down
