EDI™ Dual Chamber Vacuum Boxes

Achieve better stabilization of extruded film with an EDI Dual Chamber Vacuum Box than with other web-impingement devices. 

Benefits:

  • Simplify cleaning, maintenance, and installation with stainless steel construction and swing-out, split chamber design

 

Features:

  • Pre-sweep chamber removes the entrained air between the surface of the casting roll and the film
  • Secondary chamber develops a higher vacuum that stabilizes the film forming area, reducing neck-in and controlling the movement of the film's edge
  • Various blade configurations available, including an adjustable blade located at the pre-sweep section and a blade located between the pre-sweep and primary chambers
