CSC-C Screen changer with candle filter elements MAAG’s CSC-C large scale screen changer with candle filter elements is the right...

MAAG vessel filter technology Large scale vessel filter with external or integrated switch over valve The proven large scale vessel technology is available as continuous duplex twin vessel execution in all sizes according to flux rate, filter fineness and media requirements, and as simplex single vessel execution for batch applications as well. The duplex filter design can be executed with external or integrated switch over valve, according to the installation and handling demands. duplex-PV Filter vessel with external 3-way valve (piston design) MAAG duplex-PV is the cost-effective large area filtration...

Continuous CSC-C screen changers from MAAG, with their robust and leak-free operation, meet the highest quality standards. The sturdy design is based on the proven double or quad piston design that operates reliably without any additional seals. On the filter inlet side, rheologically optimized flow channels divide the melt stream into the 2 or 4 pistons in equal parts. Downstream of the candle filter elements, the cleaned partial melt streams converge again and flow out of the filter housing as on single polymer stream. Change of filter candles To change the candle bundles, each piston moves...

MAAG piston filter technology CSC-C candle filter elements The patented hexagonal pattern of the candles allows a maximized active filtration surface inside each piston cavity. CSC-C candle filter elements The amount, design, and filter media of the candle filter elements are tailor-made in regards of polymer type, melt viscosity, and filter fineness. According to the application, a typical demand for CSC-C candle filter elements is to remove solid black spots or soft gel contamination. Wire screen Fiber metal felt CSC-C candle replacement The used candle bundle can be lifted easily with a gripper and...

Continuous CSC-R screen changers from MAAG, with their robust and leak-free operation, meet highest quality standards. The sturdy design is based on the proven double or quad piston design that operates reliably without any additional seals. On the filter inlet side, rheological optimized flow channels divide the melt stream into the 2 or 4 pistons at equal parts. Downstream of the curved screens, the cleaned partial melt streams converge again and flow out of the filter housing as a single polymer stream. Change of curved screens To change the curved screens, each piston moves out separately,...

MAAG piston filter technology CSC-R curved filter screens The patented curved screens are pre-formed to fit tight on the breaker plate and ensure a fail-safe sealing at the complete rim. CSC-R curved filter screens The amount of screen layers, weave type, or fiber metal felt (FMF) of the curved screens are tailor-made in regards of polymer type, melt viscosity and filter fineness. According to the application, a typical demand for CSC-R screens is to retain reliable solid black spot contaminations at a high flux rate. Wire screen Fiber metal felt CSC-R curved filter replacement The used curved screen...

MAAG piston filter technology CSC-C and CSC-R Installation MAAG large scale screen changers can be installed for vertical or horizontal melt flow directly at the reactor discharge melt pump or pelletizer booster melt pump. The direct assembly of the screen changer to other process components without additional piping ensures the shortest possible line length and melt residence time between the extruder or reactor and the pelletizer. Horizontal melt flow installation Operator side left Inlet MAAG extrex® booster pump Outlet MAAG SPHERO® underwater pelletizer Horizontal melt flow installation Operator...
