Description of Dual column automatic self cleaning filter

Double-piston continuous screen changer is designed to consist of two pistons with each containing a filter screen,the two screens work at the same time,when a screen change is required,one of the pistons is Moved out while the other remains in the operating position,and the melt flows continuously through the other piston,the pressure fluctuation is small,thereby meeting the requirement of high quality production.

Performance characteristics of Dual column automatic self cleaning filter

1. There is no need to stop the machine when changing the screen; no material Leakage or production interrupt; Dual channels for filtration; Material leading and air exhausting design.

2. No need to stop the working machine when changing the screen, easy to operate and maintain, reliable for higher production output and lower energy consumption, 80%-90% down of waste material caused by screen changing.

3. Simple construction, reliable operation; Easy maintenance, lower running cost; Automatic screen changing by hydraulic; Machine non-stopped with screen changing.

Application fields of Dual column automatic self cleaning filter

Applicable to the production of various thermoplastic, chemical fiber, rubber, collosols, adhesive, coating and finishing materials alike, mainly used for filtration of the material mixture.
