Process flow cell vacStream

Overview
vacStream vacuum tanks are engineered for PO and PVC pipe extrusion across a wide range of diameters and production requirements. The product family is modular and configurable for single- or multi-chamber operation, fast dimension change (FDC) and twin-strand extrusion. Designed for process stability, energy efficiency and easy integration into extrusion lines.
