It is a symbol of internationally advanced technology, and is especially applicable for the machines of waste recycling and granulating, and direct waste processing. It is applied in the process of medium and large production lines with the features of high precision filtration, large production flow, good stability, and high automation.
The advantages of this back flush screen changer- melt filter are very remarkable.
1,Filtering area from 365 cm2 to 10000 cm2, initiative internationally (international patent)

7,Back flush screen changer is an automatic filter, thanks to an inner PLC: therefore, it does not require any operator.
8,It is self-cleaning: it cleans only when it is necessary, avoiding waste of time and material.
The following models are available covering a very large production rate. The customer can thus choose the right filter to its production:
