? The double-column four-station filter channels can work alternately, allowing for quick screen changing and easy production & maintenance.

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

? The filter plate 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 filter screen 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 extruders of various standards.

? The filter plate is equipped with detachable device to facilitate removing of cold material in the filter hole, so that the product is not affected by the cold material flow, contributing to higher product consistence.

? Start the exhaust control system when changing the screen to effectively solve the bubble problem.

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

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

? The performance is not compromised under the pressure of 25-30Mpa and temperature up to about 300°C.
