Laser Filter

Continuous melt filter for thermoplastics

Conventional melt filtering technology on the market fails to meet filtration requirements in many cases. This is all the more so if the used plastic waste is to be used to manufacture pellets in film quality. In order to fulfil these requirements, EREMA has developed a continuous high-capacity filtering system – the Laser Filter.

Laser Filter technology

Laser technology used for ultra-fine boreholes on the filter screens
Borehole self-cleaning effect achieved through conical shape
Screen discs made of hardened special steel
Scraper elements manufactured from highly wear resistant material

Laser Filter - field of application

Filtration of plastic melts with non-melting content such as paper, wood, aluminium, copper etc.
The service life of the system’s wear parts (screen discs and scrapers) is influenced by the type and degree of the contaminants

Technical benefits

Very high discharge capacity for contaminants such as paper, wood, aluminium, copper etc.
Continuous filtration over days and weeks
Fully automatic, constant pressure operation
Self-cleaning filter system with rotating scraper disc to clean the screen

Economic benefits

Less labour required thanks to longer screen change intervals
Simple and fast screen disc changeover
Extremely low melt loss
