The periodical reject separator type OS-4U is designed for continuous removal of heavy reject from waste paper without fiber loss and pulper downtime.
The separator type OS-4U can be installed after on almost any pulper: vertical or horizontal with a volume of up to 50m3. The drive energy consumption is 45 kW. The volume of the vat t is 4.0 m3.
