Polymer filtration systems from BB Engineering
Polymers can carry a variety of micropollutants that have a negative impact on your manufacturing process, your production equipment, and the properties of your end product. With our range of polymer filters, you can achieve a clean, pure melt and thus the ideal basis for any further processing in various applications. Especially in the production of challenging products such as films and spun yarns, melt filters are essential to ensure a high quality of the material. In the same way, the field of plastics recycling cannot do without melt filters. Effective filtration is essential here – both in the recycling of PET waste, and in the further processing of recycled materials into high-quality new products.
Our product portfolio serves various applications, polymers, and throughputs. In addition to melt filters, we supply an innovative melt filter cleaning system. Each of our filtration products includes decades of experience as well as only high-quality components to ensure efficient processes and trouble-free operation.
We offer polymer filters with filter areas from small to large.
Discontinuous filters
Long-Life Filter (LLF) 0,1 m² – 40 m²
Horizontal Candle Filter (HCF) 0,1 m² – 1,5m²
Continuous filters
Continuous Vertical Filter (CVF) 2x 0,4 m² – 2x 8 m²
Non-Stop Filter (NSF) 2x 1,8 m² – 2x 40 m²
Our discontinuous polymer melt filter is available in many sizes and is characterized by particularly long service lives.

Our continuous and discontinuous polymer filtration systems are mainly used within biax film lines (for packaging, display & screen, capacitor, battery separator films), spinning lines (POY, FDY) and PET recycling processes (pelletizing, spinning).
Polymer filters from BB Engineering can process PP, PA6, PET, among others.
Discontinuous polymer filters have a filter chamber that requires temporary interruption of operation for replacement/cleaning. Continuous polymer filters have two filter chambers – one in operation and one in standby. To clean one filter element, the melt flow is switched to the second filter chamber so that operation does not have to be stopped.
In our polymer filters, combinations of different-fine wire cloth layers and sintered metal fiber fleece are used. The filter elements are installed in candle-shaped and disc-shaped filter elements.
