OptiScreen ProFS
The single-stage OptiScreen ProFS screens are designed for all fine-screening applications in mechanical pulping, recycled fiber and stock preparation. The screens ensure targeted pulp quality and high, single-unit screening capacity.
The screen is based on today’s highly competitive screening technology. Therefore, it features many new and improved benefits, such as superior reliability, low investment cost and easy maintenance.
The ProFS screen family is based on Valmet’s comprehensive screening experience from more than 3,000 references in low and high-consistency applications and on the company’s in-house screen basket technology.
The correct combination of rotor and optimal screen basket ensures uniform consistency and pulp flow through the screening area in a consistency range of 0.5 to 4.5%. The extensive range of ProFS screens, with eight unit sizes, ensures the optimal screen choice for every installation.
