Vacuum Suction Press Roll

The Vacuum Suction Press Roll is a critical component in medium- and high-speed paper machines, designed to optimize dewatering and press performance. Featuring a vacuum chamber that efficiently extracts air through holes in the roll shell, it enhances the press section's overall effectiveness. By utilizing high-strength metals and a thinner roll shell, this roll ensures improved dehydration efficiency while maintaining structural integrity.

The roll shell is coated with a durable rubber layer of 30-40 mm thickness. This encapsulation promotes uniform pressure distribution, reduces felt wear, and increases press line pressure. Additionally, the optimized hole layout—with smaller axial and circumferential center distances and a higher hole count—maximizes water removal, minimizes embossing, and extends felt service life.

• Enhanced Dewatering Efficiency: The vacuum chamber and optimized hole design significantly improve water removal, even under demanding conditions.

• Durable Construction: High-strength metals and a thin roll shell balance durability with efficient air suction.

• Uniform Pressure Distribution: The 30-40 mm rubber coating ensures even pressure application, reducing felt wear and improving press line pressure.

• Extended Felt Lifespan: Reduced abrasion and improved pressure uniformity help prolong felt life, reducing replacement costs.

• Improved Paper Quality: Minimizes embossing for a smoother, higher-quality paper surface.

• Ideal for High-Speed Machines: Specifically designed to meet the demands of medium- and high-speed paper production.
