The AS-H Winklepress comes in two models - the 97 and the WPN. The Winklepress 97 is a tried and true open unit, ideal for applications where high dry solids are required.

The Winklepress WPN is the newer, closed model that produces a 4% increase in dewatering area due to the optimized roller configuration and longer belt path. The unit also features an upgraded motor that achieves approximately 6% lower energy consumption. And the enclosed design reduces odor emissions - a popular choice of wastewater plants in more heavily populated areas.
