Product Description
The Ultra High Vacuum Box is an advanced component in paper pulp stock preparation systems, designed to optimize dewatering performance and improve energy efficiency. Tailored to meet varying paper machine parameters, it features high-precision ceramic foils with surface roughness below Ra0.1, achieving a mirror-like finish for smooth operation.
Equipped with an adjustable, water-lubricated edge sealing system, the Ultra High Vacuum Box effectively minimizes vacuum kinetic energy consumption while reducing wear and tear on forming wires. It is suitable for high-speed paper machines, including those operating at speeds exceeding 3000 m/min, with the option of using ABM-SiN ceramic foils for superior performance.
