EDI® Dual Chamber Vacuum Boxes
Achieve better stabilization of extruded film with an EDI Dual Chamber Vacuum Box than with other web-impingement devices.
- Simplify cleaning, maintenance, and installation with stainless steel construction and swing-out, split chamber design
- 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
