? The double-board four-station filter channel can work alternately, allow for quick screen changing without stopping the machine and easy production & maintenance.

? When the filter flashboard is in production and reaches the predetermined pressure, the screen can be hydraulically changed.

? The flashboard filter channel has a split design to ensure no dead angle. The filter area is more than one time of the ordinary filter’s, contributing to a longer screen change interval. Fit for application in the production of heat sensitive materials such as PVC which are prone to buildup.

? With the help of hydraulic system, the slag on the filter screen is quickly pushed out of the working position, the melt around the filter screen hole is quickly cleaned and the filter screen on the ram is replaced.

? Employ automatic adjustment sealing device to ensure a sealing performance of 99%; Meet the requirement for high-output extrusion production of any raw material, and can be used together with different standard extruders.

? A preheating device is available to preheat the raw material to the production temperature in advance, so that the product is not affected by the cold material flow, contributing to higher product consistence.

? High wear resistance, high pressure resistance, high precision filter design, improved effective area and filtration quality.

? The quick change time of single-board double-station changer is ≤ 2 seconds, and the filter area is optional from ￠30mm to ￠350mm.

? The performance will not be compromised under a pressure between 25-30Mpa, and a temperature of about 300°C.
