The low vacuum suction box combines the two functions of pressure difference dehydration and scraping, so that its dehydration capacity is larger than that of the case roller and the chopping board, and is smaller than that of the ordinary vacuum box. It absorbs water but does not inhale (the paper sheet before the water line is a suspension body, no air passes through), so it is called the low vacuum suction box.
Low Vacuum Suction Box is fixed on a closed box by several panel strips with sharp front edge, forming a wide box surface with multiple narrow slots. The panel material is the same as the chopping board. The box is welded with stainless steel. Vacuum is produced by water regression.

1.Ultra-fine grain/Uniform and dense;
2.Low friction coefficient;
3.Stable structure;
4.High-strength matrix of fiber glass/carbon fiber;
5.Firmly fixed structure;
6.Easy to replace;
7.Low adhesive rate for mixtures;
8.Effectively protect forming wire;
9.Long service life.
10.High wear resistance.
The Low Vacuum Suction Box has stable dehydration, easy adjustment, high retention rate of fine fiber and filler, which can improve the difference between the two sides of the paper; instead of the table roller or cutting board, it can shorten the length of the web, or reduce the concentration of the pulp on the net, so as to improve the uniformity of the wet paper forming.
1.The surface is sandblasted, so as to make the appearance beautiful and generous.
2.Panel through the whole process, the use of special tools and special processing technology, make integral high machining accuracy, surface smooth, bright and clean degree high, smooth, delicate, in use process can avoid fines left and top plasma phenomenon
3.Easy to control water, avoid in the process of dehydration caused by unfavorable to the formation of the sheet, reduce the both sides of the paper is poor, greatly improve the evenness and smoothness of the paper,
4.The water film between the net and dehydration components, improving wear resistance, decrease network loss and energy consumption greatly.
