MAAG

The continuous melt filters in the ERF series are suitable for materials with up to 16% by weight contamination and are guaranteed to remain in use for long periods without changing the filter. Our ERF melt filters are capable of processing a wide range of polymers (e.g. LDPE, LLDPE, HDPE, PP, PS, ABS, PC / ABS, TPE, TPU, POM). All solid or elastomer foreign particles such as paper,wood, aluminum, copper, rubber, silicone, or high-melting polymer composites are efficiently removed.
The classic application for ERF melt filters is repelletizing lines, but they are also successfully employed for sheet and profile extrusion. ERF melt filters can in principle be used in any extrusion line – either single or twin-screw and irrespective of the type of pelletizing system or other downstream unit. Three different sizes enable throughputs from 150 to 10,000 kg/h depending on the application.

Automtic self cleaning screen changer for polymer extrusion industry and filtration systems 

MAAG backflush automatic self cleaning screen changers are based on the proven double-piston design which operates without any mechanical seals. The screen changers are equipped with four screen cavities. This design is used mainly in recycling applications for filtration systems.

MAAG’s CSC-R large scale screen changer with curved screens is designed for the use of one-way filter screens which do not require cleaning after the simple and safe screen change. The screen bearing pistons belong to MAAG’s modular filter system and its patented design use 75% of the piston surface as active filtration area. Also this filter execution can be installed for vertical or horizontal melt flow directly at the reactor discharge melt pump or pelletizer booster melt pump to avoid additional piping for reduction of melt residence time.

Suitable for Resin & Virgin Polymer Production

MAAG’s CSC-C large scale screen changer with candle filter elements is the right choice if short melt residence time, small footprint and a simplified candle change are required. Depending on the polymer type, melt viscosity, reactor throughput, and filter fineness, the screen changer size and number of pistons are customized to the application. The patented design allows the use of pleated micronex® candle filter elements with fiber metal felt (FMF) media, or cylindrical Multinex candles filter elements with interchangeable filter sleeves.

Suitable for Resin & Virgin Polymer Production

MAAG-designed simplex polymer filter systems can be provided with either fixed or removable vessels. A compact preheat station with spare vessel is also available for locating near the polymer processing line for quick changeout. They are custom designed to minimize initial pressure drop and maximize polymer filter element life. Our proprietary sizing program, based on more than 20 years of experience in the field of polymer production and extrusion, incorporates your operating data to size each system for maximum performance and optimized flow while maintaining compact dimensions.

Polymer filter candles and application for masterbatch and polymer filtration

MAAG multinex polymer filter candles are tailor-made for use in continuously operating dual bolt screen changers of the MAAG CSC-P/C series for polymer filtration.Compared to typical polymer application round screen plates, they increase the active screening area up to 60

Polymer application and polymer filtration with filter elements for large areas

MAAG offers high-quality polymer filter elements designed for long term use and multiple cleanings. MAAG can provide standard design polymer application or build to your requirements regarding:

MAAG’s new generation Duplex Filter System (DFS). The new DFS incorporates a new patented solid body DIVEXpro switch over valve. The vent and drain valves are also newly designed and integrated into the body of the DIVEXpro. Combined with MAAG’s established MICRONEX® filter candles the new generation filter system can meet the harsh demands of polymer filtration. For chemical recycling applications with low viscosity and high contamination levels the new generation DFS-BF is capable of performing an automated backflush cleaning of the filter candles during operation.

Optimized flat screen changer for processing of plastics

The flow optimized new version of MAAG´s FSC hydraulic and manual screen changers assist operators of plastic extrusion lines in achieving a reduced equipment footprint, reduced residence time and improved residence time distribution. 

Manual screen changers from Maag have been the first choice of cost-effective filtration systems in extrusion lines for many years. Starting at size 45, the manual screen changers optionally come with transmission gearing. Here, the breaker plate is equipped with patented gearing and a pinion which allows an effortless screen change even in restricted space conditions or high sealing pressures. The manual screen changer guarantees the protection of gear pumps and fine extrusion die gaps from damage and dirt accumulation.
